Warning! This video gets kinda gross…especially for me.

After we banded birds this morning at Carpenter Nature Center, I was asked if I could help feed some of their education birds of prey. Their red-tailed hawk is a very easy going imprinted bird. He eats easily from the hand, so I thought I would take a quick video so you could get an idea of what it’s like to watch a red-tail up close as he eats a gutted mouse. Well, he got a chunk of mouse lodged in the wrong way and tried to gag it out as if it were a pellet…

And there you have it, the chunk of mouse nailed me right in the kisser. I don’t know if you caught it, but you can see a red smudge on the right side of my mouth–from the offending piece of regurgitated mouse.

Here’s what hit me. It’s bad enough feeding peregrines who pluck feathers all over you, but leave it to a red-tail to up the ante and nail you with actual flesh.
Yuck. The price I pay for cool birding experiences.

I just have too many photos that I took Tuesday during what the local weathermen are calling “an inconvenient snow” (because it was only 2 inches that fell, but it hit during rush hour snarling traffic in the worst way). The first was the snowy owl and then I headed over to the Minnesota Valley NWR Visitor Center. I figured the feeders would be active between the snow and the sub zero temps.

They were so active, I have to divide up what I saw, otherwise we might get 45 photos in one blog entry.

One of the coolest things that happened was as I was leaving the visitor center. A young red-tailed hawk (young because the tail is brown and stripey, not brick red like it would be on an adult) was perched on the parking lot security camera. I wanted to get home because it was after 3pm and I knew with the snow, traffic would be snarled. I took a few shots and walked to my car.

I tried not to stare at the hawk while I walked to my car. Staring can make a bird nervous and this one seemed to be actively hunting and I didn’t want to add to its effort in the cold and snow. It paid very little attention to me and I digiscoped one more image before my aching, freezing fingers alerted me that they had had enough. I opened my car door and turn to load in my scope when I heard what I can only describe as hawk wings hitting something (I hear it from time to time at The Raptor Center and at the hawk blind). I looked up and saw that the red-tail was no longer on the camera post and at first thought that it had flown away, but that would not account for the sound I heard. Then I looked to my left and just a few yards away in the grass I saw…

The hawk with some sort of prey, I think it’s a mouse! Fortunately, my scope was still up, I quickly slid the camera adaptor back on the scope (thank goodness for that DCA adaptor) and got the above photo. My camera batteries finally died right after I took it but I watched the hawk swallow the rodent whole and then it took off.

It took a good five minutes before feeling returned to my fingers and I got stuck in traffic, but it was so worth it to see that!

Yes, I did just make that joke.

It was hard to contain any Twin Cities resident indoors today. After sub zero temps, the weather really warmed up to the twenties and thirties over the weekend and today it got to the low to mid forties–whoot. And we need to gather our rosebuds while we may, because tonight it’s rain that turns to ice as the temperature is supposed to plummet to a low of 3–which as coincidence would have it will be our high for tomorrow, with the temps going somewhere in the neighborhood of -14. That’s about a 60 degree change in the next twenty-four hours–how do we not a get winter tornado with that?

So, it was take the spring like day while you can. I took a quick jaunt over to the Minnesota Valley NWR. When I arrived, I could hear an angry red squirrel squeaking and general angry bird chips. I wondered if the sharp-shinned hawk was around and dashed behind the Visitor’s Center.

Well, it wasn’t a sharpie, but a young red-tailed hawk (not the yellow eye and the lack of red in the tail). It was half heartedly preening its feathers and bobbing its head watching was moving below. It was close, but not in the best light.

Some of the birds seemed to sense that they weren’t high on the prey item list for this species of hawk and returned to the bird feeder. But, young hawks are unpredictable because they’ll try anything once, so birds that did brave the feeders, keep a watchful eye towards the hawk.

I think the red-tail got tired of the squeaky red squirrel and it flew down the hill towards the river–which was great because I could get a photo with a better background. The only problem was that it was facing away from me. So, I did my best whistled impersonation of a red-tailed hawk scream and it looked at me. Great day with a great hawk. And with that, I left it to hunt in peace.

At first when I was looking at my schedule and budget for the fall, I was worried I just wouldn’t be able to get to my friend Frank Taylor’s hawk banding station–my favorite bird activity I do all year. I was very down that I would not get to see a northern goshawk (my favorite raptor and next tattoo) fly into the nets But thanks to help from my great friends, I managed two trips. And I got to see a first year northern goshawk fly in! Whoot!

Frank asked me to hold the young goshawk so he could get photos and I gave my camera to a wonderful woman I’ve been getting to know at the blind named Joan. We were working as swiftly as possible with the goshawk so we could send it on its way.

Why would we want this magnificent bird away so quickly? Because the moment it hits the nets to the very second it is released, it give a loud, piercing, melt-your-eardrums shriek over and over and over. All we’re doing is holding it, it’s not in any pain what so ever. Such a big bird, such a big whiner. Even the smaller cousins of this accipiter, the sharp-shinned hawk and the Cooper’s hawk take the banding process with stoicism. Frank wanted to try and get a photo of the goshawk with its mouth closed–not an easy feat.

I think this photo that Joan got about sums it up. Yes, here I am with my favorite raptor and you can see that I’m clearly thinking, “Are we done yet? Can we move on?” I bet you’re now curious, just how awful this sound is, aren’t you? Okay, here is about five seconds of ear-splitting goshawk (those you cannot view video should be grateful):

Annoying, huh? As if that weren’t bad enough…

The goshawk started attacking my coat. It was time to set this bird free and continue on its way.

I tossed the bird in the air and Joan got this great shot which actually looks like the bird is reaching out to attack me. Actually, what’s going on is that I tossed the goshawk out to the field, but being the type of hawk that hunts in the woods, the bird is turning around in mid air so it can fly into the safety of the trees behind me. Still, I love how it looks like I’m reaching out it and the goshawk looks like it is going to nail me.

More banding fun to come!

I keep trying to write this blog entry, but my rabbit insists on using me as a jungle gym, making typing most difficult.

Here’s a photo of last weekend’s banding crew (the only bummer is that Frank Taylor, the guy who runs the blind isn’t in it). But from left to right we have Reier Grudem, Joan Schnabel, me, Amber Burnette (holding a red-tailed hawk), Rick Dupont, and Katy Dupont.

Frank Taylor just included this photo in his weekly banding report. That’s me in the pigeon yanking seat holding the pigeon line and a sharp-shinned hawk I lured into the banding station by pulling the pigeon. Whoot!

Above are two haggard (adult) sharp-shinned hawks. So, I gave you the info for how we have the banding station set up, now let’s talk about some of the interesting things observed over last weekend. First off, birds were all over, both songbirds and raptors. Saturday morning, Amber, Reier and I arrived at the field and could see sharp-shinned hawks, harriers, merlins all moving and could hear blue jays all over. You would see flocks of blue jays miles away in your binoculars and there would always be at least one sharp-shinned hawk mixed in with the flock.

In the above photo is both a haggard (towards the back) and a passage (first year) sharp-shinned hawk. Note the difference in eye color and that the younger bird is brown and white and the older birds is dark blue with and orange breast. The passage sharp-shins were in hunting mode and were bound and determined to take out a blue jay. You would hear a flock of blue jays screaming and then all of a sudden you’d hear one give a strange honking call and that was usually a shin hot on its tail. We also saw flocks of smaller birds in the fields in front of the blind. At one point we had a white-crowned sparrow feeding in the grass in front of us. Just as we identified what type of sparrow it was, a passage sharp-shinned hawk flew down, landed on it, killed it and flew away with it’s prize–in less than 40 seconds. It’s was a much more effortless affair than the Cooper’s hawk incident from yesterday.

Above is an up close shot of a haggard sharp-shinned. It was one of the busiest weekends I’ve ever experienced at this little hawk banding station. On Saturday we banded 32 birds (29 sharp-shins and 3 red-tails) and on Sunday we banded 34 birds on Sunday (33 sharp-shins, and 1 Merlin). We did have quite a few heart breaks, including birds bouncing out of the nets before we could get to them and one mouthy little female kestrel. When the kestrels come into the net, you are sure they are going to come in, but they always seem to find the net at the last second and dodge out of the way. This particular female, flew right to us with no intention of going for the pigeon and landed on one of the poles that holds the net. She looked directly to the blind and gave the loud kestrel cry–pretty much the equivalent of giving us the bird. It was as if she were screaming, “Hey, I know you guys are here and any predator withing the sound of my voice should stay away!!” We must have had her in the nets before.

Here’s a haggard red-tailed hawk that came into the nets. This bird was a bit thin and its bill was a tad crusty looking. As Amber was banding it, she noticed that the left eye was clouded over. When you waved a finger in front of it, the hawk could see out of it at all.

Obviously the hawk had not been surviving well with this disability, but it had been surviving. Who knows exactly how long the birds had been living with sight in only one eye. The bird has been alive at least three years. When red-tailed hawks are young, they have yellow eyes (note the yellow eyes of a passage red-tailed hawk in the next photo). Their eyes get darker as they get older, this bird could very well be 15 years old. Glaucoma doesn’t develop overnight, perhaps it has been such a gradual change the hawk has had a chance to adjust it’s hunting style. Reier noted how it flew to take to view the bait pigeon and really, had the nets not been there, it would have been able to catch it. There really aren’t any treatments for bird glaucoma so taking to the Raptor Center wasn’t an option. After banding it, we let it go. Maybe it will survive another few years or maybe it’s going to end its last days in a blaze of glory.

For a comparison, here’s a very healthy passage red-tailed hawk, note the yellow eyes? This bird was having some tail issues:

Check it out, it’s missing quite a few feather and has a mixture of both first year red-tail brown feathers and a red tail feather–what the heck is going on? Frank speculated that the tails feathers had been grabbed, maybe by another red-tail in a territorial fight, or by a nest mate, or even some other predator. The feathers are starting to grow back in, and the new feathers are growing in red because the body says “hey, after the second set, these should be red” but at the same time, the feathers are supposed to be brown striped, so you get some striping in there too. And since we have a photo of a red-tailed hawk with the wing extended, note how the wings look very long in relation to the body, and the tail is short in relation to the body–this is a characteristic of this type of hawk, known as a buteo. Compare that to a different hawk:

Here is a sharp-shinned hawk, they are accipiters and they have a shorter wing in relation to the body, and a very long tail–that’s one way you can start to id hawks. When you see one, try to note if the tail is long or short compared to the body and if the wings look long or short. Incidentally, this is one of the birds that I lured into the nets.

The birds were coming into the nets so quickly, that at times we barely had time to get photos or to release banded birds. We were getting ready to release this merlin (in front) and this sharp-shin when Rick yelled that some birds were coming into the nets. We just ran behind the blind rather than taking the time to go in. Sometimes that’s faster and if you’re quiet, the birds will still come into the nets. I was going to take a photo of these two when all of a sudden both looked up. They were seeing hawks fly over too.

When we have a chance, I like to get photos of people releasing hawks. My favorite thing to do is lay on the ground and get a wing shot of the bird. When you release a sharp-shinned hawk, you can pretty much just open your hand and they take off towards the woods right away.

Reier got a photo of me releasing a red-tailed hawk. They are little heftier and you have to kind of fling them into the air so they don’t just thunk on the ground. Unlike the sharp-shinned hawks that head straight for the safety of the woods as soon as they are released, red-tails stay in the open and try to find the nearest thermal to lift high into the sky.

At one point we had two sharp-shins to release and one merlin. We released them all on once (that’s the merlin in the middle). Note the shin on the right aiming right for me? That was courtesy of Katy. I told her that she could just let it drop towards me, boy I think she kind of threw it at me. It’s okay, I had it coming, I was making fun of her for texting her friends from the blind. And if you’re worried, the bird didn’t hit me and made it safely to the woods.

We got to do several multiple releases. Here’s a video of a sharp-shinned hawk release. I’m holding a sharp-shin and aiming my camera at my hands. But since two people next to me are releasing birds, it looks like a magic trick: one bird turns into three:

And for those who can’t see video, here’s a couple of consolation photos:

Haggard sharp-shinned hawk.

We interrupt the regularly scheduled report on last weekend’s hawk banding to inform you of an urban Cooper’s hawk observation that happened today.

WARNING! This post is not for the squeamish. In Nature, the fight for survival can be brutal and this post is going to describe an incident between a hawk and a pigeon. If you would rather think of all the animals and birds getting along like a Leo the Lion cartoon, you may want to skip reading the rest of this post.

I needed to take care of some grocery shopping this afternoon before we were hit with a line of thunder storms. When we came back from Duluth last night, you could feel the humidity, I had a tough time sleeping last and the air felt heavier throughout the day today. I left to go shopping and I as I walked past the side of my building, I noticed an odd lump next the bushes that border the apartment building’s property. It suddenly dawned on me that the shape was a Cooper’s hawk mantling over prey. There was white flash and I realized it had a pigeon and it wasn’t quite dead. So, I dashed upstairs to my apartment for my digiscoping equipment.

I came back down and the hawk had changed position and was facing me with the pigeon. This was a Cooper’s hawk hatched this year based on the brown and white plumage. It’s also a female based on her size compared to the pigeon–she’s a big ole girl. The hawk seemed antsy, and had a tough time balancing on top of the pigeon. When I took the second photo, I found out why:

The pigeon was still alive and struggling to free itself from the inexperienced hunter. I have always thought that Cooper’s hawk was one of the worst ways to go–especially a young one that doesn’t quite know how to use all of its equipment yet. Cooper’s hawks squeeze repeatedly, and since their toes and talons are thinner than a red-tailed hawk, it’s kind of like a death by sewing machine needles. When a Coops starts to feed, prey isn’t always dead. Experienced birds can kill quicker, it makes it easier to feed and they don’t waste as much energy. I started to debate with myself as to how long I can watch this, let alone take photos.

And then the pigeon rolled and was free (I took a photo but all that was left was a few feathers floating), it took off like a shot right over my head, the Cooper’s followed in hot pursuit at eye level with me to the right side of my face. I felt a slight breeze in its wake. The pigeon crossed the busy street right over the cars, the Cooper’s gained quickly. The pigeon raced over a parking lot towards some trees, the hawk caught up and nailed it in mid air, there was a puff of feathers and both fell to the ground.

I crossed the street at searched the parking lot. The young Cooper’s hawk had made it to a small yard at the other end of the lot. If you look between the dark gray car and the yellow garage, you can see a small lump on the ground. That’s the hawk. Don’t worry, I got her in the scope:

The pigeon was still putting up a fight, although not much. You could still see it breathing the scope. The young and hungry hawk could no longer wait and had to feed.

You will note in some of the photos that her mouth is open. She was panting hard. I could feel sweat dripping down my back under my rain jacket from the humid conditions, I can’t imagine what it feels like when you can’t sweat, have to fly hard and try and kill something half your size to survive. I didn’t approach any closer to the hawk, she was having a tough enough go at trying to eat for the day and I could get good enough photos from this distance.

As she was feeding, the pigeon finally stopped struggling and breathing. A few times the hawk would mantle–spread out her wings and tail to look big and intimidating and hide the prey. I wondered what would cause that.

I soon had my answer. A gray squirrel was investigating the situation, squealing out its protest of the hawk near its tree. I could hear cardinals chipping a warning to each other and robins giving their high pitched warning whistles as well. No one was happy about the Cooper’s hawk.

The hawk continued to feed and then mantled one more time. This time and older gentleman and small dog were approaching, both appeared oblivious to the feeding hawk.

The man and dog were too much and the Cooper’s flew away with its kill. I’m always amazed at what I spy in our neighborhood. I always wonder if my other neighbors ever notice this. Did the people driving down the street notice the pigeon with the hawk in pursuit mere feet in front of their windshield? I did feel bad for the pigeon (I feed them off my window ledge), but also realized that they hawk had been having a hard time of it herself just trying to survive. Will she able to continue to navigate the busy Uptown area already populated with quite a few adult Cooper’s hawks? Will she last the fall and winter?

I will say, she looked so big compared to all the tiny sharp-shinned hawks we banded this past weekend. Speaking of which, we will now return to our regularly scheduled hawk banding updates.

I’m always amazed at how closely people pay attention to the blog. When I wrote earlier that I was on a tight budget and didn’t know if I could go up hawk banding this fall, invitations came from all over for free housing. I am sometimes overwhelmed by friends and their generosity. Another example is what I say I’m going to blog about. While I was having a great time at the banding station, one of the sub banders named Rick said, “Aren’t you going to take pictures of the setup?”

“Huh?” I asked.

“You said that you were going to explain how we band the hawks up here.” he reminded me. And he was right, I do need to explain the set up so this post will explain that. One BIG point to stress about banding birds:

Because banding birds requires capturing the birds and handling them before the banding takes place, the banding of birds in the United States is controlled under the Migratory Bird Treaty Act and requires a federal banding permit. Some states require a state permit as well. Only official federal bands may be legally placed on birds that are released to the wild within the United States.

You can read more about banding birds at the Bird Banding Lab. I’m fortunate enough to know several researchers who band different types of birds (pelicans, hawks, songbirds, herons) and allow me to tag along and carry equipment and now I’m to the point where I’m actually learning to do different aspects of it. This is just how this particular banding station works and records data, every station is different. This station in Duluth, MN is run by Frank Taylor, who has been banding hawks longer than even Hawk Ridge–38 years–and he doesn’t look a day over 39.

Here are the nets. Can you see them? There are two different ones there, right in front of the trees–can’t you see them? Heck, I took the photo and I can’t even see them. Let’s look at them from a different angle:

These are the front nets and this photo was taken from the banding blind where we hide while the hawks fly in. The nets form a sort of U-shape, with the open end of the U facing the blind. There are nets surrounding the bait bird (pigeon). Most hawks aim for the pigeon and fly into the front net, but some species are able to see the front net at the last second, dodge above it and as they go up and over, end up in the nets behind the pigeon. Sometimes, they hawks are so fast and maneuver so quick, they elude both front and back nets! It’s incredible to watch the mad flight skills of all raptor species. Even a big chunky buteo like a red-tailed hawk has some fast peregrine moves inside it.

This is the pigeon harness. This is a vest of leather that covers the pigeon around the chest to protect it on the off chance a raptor grabs it when coming into the net. The harness is also attached to a pull chord.

Rick is putting the harness on one of the pigeons. The wings and feet fit through the holes comfortably and all the pigeons have to be the same size, if they are too small they can get tangled in the harness, so their weight and size is closely watched. You pull the cord, and the pigeon is aloft in the air, it flaps its wings and then flutters to the ground. The pigeon yanker has to pull, get the pigeon to flap the wings and then prevent the bird from thunking onto the ground and breaking some bones, so it does take technique to do it so the pigeon has a natural looking flight and doesn’t get injured. We use several pigeons throughout the day. If it’s a busy day and lots of hawks are flying over, a pigeon can be yanked a lot and tire easily, especially in warm weather, so you must keep an eye on the pigeon so you don’t exhaust it. Rotating the pigeons gives them a chance to relax.

Rick’s primary job at the hawk blind is pulling the pigeon, or as I affectionately call him, The Master Yanker (this is the part that I got to learn this weekend, so I guess that makes me a Novice Yanker). When a hawk is spotted, Rick has the job of controlling the pigeon. You yank the pigeons in different ways for different birds. For accipiters or for larger hawks that are far away, you yank hard and get the pigeon high in the air. For larger hawks that are close, you just kind of wiggle the cord and get the pigeon to flutter slightly, too much flapping can freak out a red-tailed hawk or bald eagle on close approach–seriously, it will. I have to say, this wears out your arms pretty quick. You pull hard and far from the blind, and sometimes you punch people sitting next to you, or knock your knuckles on the boards inside the blind, not to mention how the cord rubs the skin on your hand raw.

That’s Rick in the blind in the above photo. See the hole in the lower left corner? That’s where the pigeon chord comes into the blind. Another important job that the Master Yanker has is to pull the pigeon out of harm’s way. Some raptors dodge the nets or are so big they can still reach the the pigeon though the nets, so you have to pull the pigeon out of the way at the last second, so it doesn’t get killed. Frank has only lost 3 pigeons to raptors in the 38 years he has been doing this. As if all that isn’t pressure enough, Rick has to burst through that little door at lightening quick speed when a raptor gets in the nets before it works itself out and flies away. It’s a high pressure job, but man is it fun. I only did it for about 45 minutes and about 8 hawks flew in, two bounced out of the nets, but still I got six, man am I sore!

We watch for hawks coming in. It’s so much fun to watch a speck in the distance, identify what it is and then watch that speck come in to the nets. The red-tailed hawks are one of the coolest. You can see them from miles away, circling in a thermal and if you can figure out when its looking in the banding station’s direction, you pull the pigeon. When the red-tail sees it, the bird will flap to get out of the thermal and then set on target for the pigeon–it’s incredible once it has set, the red-tail won’t usually flap, but just hold the wings steady and come in for a dive. There’s a red-tail in the above photo. It’s hard to see, I’ll try and zoom it:

It’s interesting to watch some raptors come in low, using the vegetation behind them to hide their shape as they approach their prey. At the last second before the red-tail hits the nets, it will swing its feet forward, baring the talons–it’s like watching an airplane drop its landing gear, and sometimes you can even hear the woosh of their wings–if you’re thinking that sounds really awesome, it is.

My friend Reier took this photo from the blind. When Rick had to take a break, I asked Frank if it would be okay if I took a go at pulling the pigeon. He seemed hesitant but gave the go ahead. It took some practice to get the pigeon yanking down (and I’m still no Rick) but Frank then asked, “Sharon can you book it? You have to be fast when the hawks hit the net and grab them before they get loose.” I said I could do it. I took off each time and on the last time, my shoe got caught in the nets and I fell over, but still grabbed the hawk before it flew off. That’s me, as if I just slid into home base, holding my hand it the air, “I’m okay!” I shouted. I got the hawk, and provided comic relief–that’s what I call a job well done. I have a beauty of a bruise today and have made the extra effort to wear cropped pants to show it off. “Ew, Sharon, how did you get that nasty bruise?” and I will proudly exclaim, “Hawk banding.” I love my bruises and scars.

After the hawks are in the net, you have to untangle them quickly–and I have to say that it’s much easier to get raptors out than songbirds (you just have to watch out for the feet). That’s Reier above getting a hawk out of the net with Rick. From thew, the hawk is processed, it’s measured, banded, aged, and in some cases we try to determine sex. My buddy Amber is learning the measuring and banding end of things (and I just realized that I have tons of bird photos, but none of Amber in action), but I have to say I am a pigeon yanking junky–it’s sooooo fun–and GREAT exercise. I’m okay with how my body looks, oh sure I would like to be a but more buff or a few of my parts could be a little smaller (it would make clothes shopping for tv, ten times easier) but it’s hard to find exercise that’s not redundant and boring. Today, after doing the pigeon yanking yesterday–all the right parts of me are sore–my arms from yanking, my thighs from squatting and lunging to get hawks out of the net, my torso (I’m not sure why) but if a gym could come up with some sort of virtual hawk banding station where every ten minutes I do some sprinting to get hawks out, and pulling to get the pigeon going, I would SO sign up! You could have screens to show hawks flying in, ah, it would be so cool.

For some birds, we take photos before they are released. Seriously, little male sharp-shinned hawk, you thought trying to catch one of those pigeons who are bigger than you was a good idea?

“Yeah, and I still say I could take one!”

And then the hawk is released and we start the process over again.

I love this photo. It’s Frank (in the green fleece) standing in front of the hawk blind with some friends getting photos of the hawks that were just banded. If you look at the blind behind them, Rick is scanning the skies for more incoming hawks. Rick, Master Yanker, ever ready to bring in a hawk.

More hawk banding photos and interesting bird things we learned coming in the next entry.

I’ve posted some things that may have gotten the non raptor lovers hackles up. Like the red-tailed hawk raiding an oriole nest. Well, for those who think I show the raptors always with the upper hand, check this photo out. I’m not sure who to root for, the kestrel or the red-tail.

All I can say is, “Holy Crap!”

I’m kind of bummed, I just got Frank’s banding report for his hawk banding station for last weekend and the end of the report reminded all of us on the list that this coming weekend is the last weekend he will be banding–and I can’t go! That means I will only have been to his place once this year. How did Autumn get away from me? This happened a little bit last fall.

Mental Note for 2007: Leave more time for Frank’s banding station in the fall!

I shouldn’t complain too much, the reason I can’t go to Frank’s this weekend is that I’m going to that legendary North American birding hot spot: Cape May Autumn Weekend.

Take a look at the red-tailed hawk photo at the top of this entry. That’s a photo I took a couple of years ago at the station, but look at the pupils. Those are normal red-tailed hawk pupils. Now, take a look at the photo Frank took of a red-tailed hawk they got last weekend at the banding station:

Frank wrote, “We caught a passage (first year) Red-tail with both pupils slightly deformed. Chuck gave it the Doctor’s eye inspection and said he thought that both eyes were functioning properly.” Chuck is a doctor and one of Frank’s sub-banders. Even if the eyes weren’t functioning properly, I’m not sure what could have been done. If the pupils are deformed, you can’t really do a transplant and the bird would have to be put down. I wonder if the bird sees in double or if images are a little blurry? Can this bird find ways to hunt with this odd vision? It would have hatched at least six months ago and has been surviving and compensating somehow. So much discovered, and yet so many questions are left.

Besides the usual raptors, Frank also got in several passerines–without a bird feeder guiding them in, must be a good spot for birds passing through:

Here’s a hairy woodpecker photo that Frank took.

Here’s a blue jay photo from Frank. Blue jays are always hanging around the blind looking for left over pigeon chow. One year there was a blue jay that could mimic a broad-winged hawk. It was almost a perfect, except that the blue jay did it a little faster than an actual broad-wing…and you could hear the call well into October when we no longer have broad-winged hawks in Minnesota.

Here’s an adult eastern bluebird that found its way into the nets as well. Isn’t that just beautiful? I swear I have seen that exact same color scheme in a spring sunrise. Look at how the rust coloration works its way from the breast into the upper wing coverts and scapulars (shoulder feathers).

So, I almost got clotheslined by a Cooper’s hawk today! Above we have Jane Goggin, one of the many fabulous vets at The Raptor Center. We didn’t have any programs scheduled for my shift today so our crew asked if we could watch Jane and Lori (one of the other fabulous vets) test fly one of the 13 Cooper’s hawks still in clinic (that’s down from 24–it’s been a record year).

We followed Jane and Lori and stood behind them as they released the immature female Cooper’s. The bird had recovered from its injury and has been test flown by the volunteer flight crew (after birds have recovered from their injury they go through this to build up their muscles). Lori and Jane go out and test fly the birds to determine if the flight therapy is working and to see if the bird’s flight is strong enough for release. The bird is attached to a creance (a really long leash attached to the ankles so it can fly but not get away yet). The bird took off well in front of Lori and Jane.

Then she suddenly banked and headed straight for some spruce trees off to my right. At that point she figured out the creance was going to prevent that and she turned on a dime towards me coming up fast on my right. About two seconds after I took the above photo, I realized the creance line was heading straight towards me at about neck level. I hit the ground and heard Jane and Lori yell, “Duck! Quick!” towards the rest of our crew. I heard the line zip over and lifted my head to see the rest of the crew on the ground.

Fortunately, no one was injured and I think it’s safe to say that this particular female Cooper’s hawk is ready to go off in the wild with moves like that!

Someone emailed how I get the release shots that I posted last week. Above is a photo I took of Chuck releasing a merlin.

Here is the same scene taken by Rick Dupont of me getting the above shot of Chuck releasing the merlin.
