And it’s totally an adventure to fly over thousands of ducks on the Mississippi River, but I do enjoy surveys on the ground, enjoying the autumn air and the last ambient sounds of leaves rustling in the wind.  Almost all of yesterday was perfect.  Most of my survey spots are on the side of the road so if rain comes I can quick duck in.  I have one survey spot that is almost a mile walk from the car on uneven terrain.  It’s a lovely walk and very birdy, but I don’t mind it.

Even though I do have to wriggle under an electrified fence on my walk there. Just adds a bit of adventure to my work…and as someone mentioned on Twitter, it’s also excellent motivation for not eating too much…Non Birding Bill texted that it looked like a storm was approaching.  Normally, it’s so quiet out here I can hear a storm when it’s still 40 miles away.  I didn’t hear anything until a half hour before I was supposed to leave.

On the walk back, I could see the storm moving my way fast.  I hustled to get back to the car…except at the electric fence, I took my time there.  I could see hills disappearing and fading as the rain came closer and closer.  Just as I was putting my scope in my trunk, buckets of rain hit.  I made it just in time!  I drove to my next survey point and the hard and fast rain soon passed.  When it was finished, I noticed a couple of odd shapes.

Closer inspection revealed waterlogged red-tailed hawks.  I saw about three different birds, all in this posture.  If you’ve ever wondered what birds do after a rain–spread out the wet wings so they can air out the feathers.

Poor wet-tailed hawk!  Drenched feathers have to affect flight and one’s ability to hunt.  It’s gotta be uncomfortable too.  I wonder if they get frustrated the way humans do when rain hits after they water their yard.  Do hawks think, “Dang it, I just bathed 2 hours ago in that pond and of course it rains!”

Many of the smaller birds took refuge in the remaining corn stalks.  Warblers, sparrows and juncos were all over the leaves after the rain passed.  Above is a winter plumage chipping sparrow.  It kept flipping its wings–I would guess to try and flip off extra water on the feathers.

I have one more day of surveys today and then tonight it’s our Birds and Beers and Big Year event.  NBB though not a birder has been a huge help in the last minute preparations.  When we got the Swarovski 10×30 CLs yesterday he posted them so people could see them…and to taunt me a bit.

They are a sweet little pair of binoculars…complete with a Batman-like insignia.

That’s the nest visible through my spotting scope.  It looks like the female has a fairly light head.  The male has been very vocal chasing anyone who dares cruise through his patch of sky.  Thanks to his vocal and merry chases, I’ve discovered that a red-shouldered hawk sometimes glides through (new hawk for Neil’s yard).  To give you an idea of how well hidden the nest is, here is where my scope is aimed:

Here is an arrow for guidance:

Neil’s house is on top of a ravine, down below is a creek and the red-tailed hawk nest is in a tall pine on the other side. Since the nest is a challenge to actually get in the scope, I left it set up there while I gathered my things and repacked them in the car.  I showed groundskeeper and the housekeeper the nest and continued gathering my stuff.

When I was about about an hour of away from Horicon, I received a call from Neil, “I was just looking through your scope that you have set up on the nest, it’s lovely.  But don’t you need this for the festival.”

I pulled over and realized my error and shouted a loud, “BLERG!”  Figuring that shipping it overnight it would be impossible, I decided to drive back.  Neil’s assistant Lorraine gave the groundskeeper her car and he drove and met me halfway–which was quite nice as he had plans to go the opening of Thor that day.  But thanks to all, I got the scope and made it to the festival and learned that coffee is a good thing for me to have when birding in the morning.

Sometimes I think it takes a village to manage a Birdchick.

One owlet was easily visible with the naked eye on approach.  Great horned owls do not build their own nests, they take over old squirrel, hawk or heron nests.  They don’t even make any renovations before they use it, they just squat.  As the chicks grow, the nests soon shrink.  Between the dwindling nest and the larger chicks, the female no longer fits very well and perches near the chicks.

It appears that the nest contains two owlets!  When I arrived to the general nesting area, I could hear the crows heartily mobbing.  I saw the male fly over with a flock of about 20 crows in tow.  The chicks showed a bit of interest in the commotion but mostly laid low.

The female was very interested in the crow activity as she watched the crows surround the other owl.  What was interesting was that I thought the crows were chasing one owl, I later ran into a fellow birder who was close the crows and he said the crows were after two great horned owls and a third flew in.  I wonder now that as I was watching her keen interest in the crow activity, if she was responding to an intruding great horned owl into her territory rather than the corvids gathering around her mate?

She soon left the nest to try to get a better look at the mobbing crows but still would turn around to keep an eye on her chicks.  It was so strange to me to see a secretive owl perched out in the open in the middle of the morning.  Not long after I took this photo, she bolted off into the middle of the flock of crows.  The owls all went in separate directions and the crows split their murder into 2 smaller groups, diving and cawing at the owls.

With the female away, the young owlets closed their eyes and assumed an upright position.  I wondered if this was all part of a camoflauge instinct?  With the adults going after the crows, it stirred up the surrounding birds.  Robins began giving their alarm calls and then an adult Cooper’s hawk flew in.  The hawk missed its intended prey…then suddenly noticed one of the owls and started diving at it and screaming its call.  If you’re not familiar with a Cooper’s hawk mobbing an owl, let me remind you of the video of the Cooper’s hawk mobbing a plastic owl (they never work to scare birds away).

The Cooper’s hawk then made a wider pass and went straight for the owl nest, hell bent on mobbing the chicks.  First it bounced off the nest and then started to make a second dive, by that time, the female great horned owl was back on the nest and ready to kick some serious accipiter ass if it tried it again.  I have never seen a great horned move so fast in my entire life.  I’ve always referred to them as the Sunday drivers of the raptor world…I got schooled–they can move very fast when they need to.  The above photo is on the Cooper’s hawk’s second attempt at a dive on the nest.  The blur above the nest is the female owl defending her chicks.

The angry Cooper’s hawk perched nearby and shrieked out angry, “kek kek kek kek kek keks” at the great horned owl.  I suspect this bird has a nest nearby.

The great horned owl stood at her nest above her chicks and hooted back her retorts after every kek the Cooper’s hawk gave her. The owl even barked a few times in warning at the hawk.  It was the weirdest argument I’d ever heard.  As the two continued, a few crows gathered nearby to continue their remarks on the two predators they detested.  Then, out of nowhere, a broad-winged hawk screamed nearby.  Three raptors all at once! An owl, a buteo and an accipiter.

The chicks nestled against the female as if to say, “Yeah, my mom is awesome.”

I wondered, how long was this battle going to last?  The suspense was killing me…then I got my answer.  I heard a helicopter coming fast and approaching low.

This was not digiscoped, this helicopter was THAT low.  It was Metropolitan Mosquito Control dropping their corn pellets full of Bti and Methoprene to kill of mosquito larvae.  The helicopter skirted the tops of the trees, the owl, crows and hawk scattered.  The adult female owl apparently thought, “Cooper’s hawk, yeah, I can kill that,” but when the helicopter appeared her attitude shifted to, “yikes, too big for me kids, you’re on your own, see ya!”

After the raptors scattered, pellets rained down and bounced off my body.  I could hear nearby woodpeckers give low warning noises to each other.  Robins were on high alert.

A couple of nearby mallards seemed to dig the pellets and tried to eat them as soon as they hit the water–they were the only birds who seemed to be unaffected by the strange aerial machine.  The city assures me that the pellets are harmless both to me and the wildlife that might consume it.  I was tempted to start running around like Cary Grant in a Hitchcock movie, but it’s not so much fun with a spotting scope in tow.

The helicopter made a few more passes and a few moments later, one of the owls flew back with a few pesky crows hot on its tail.

She perched right above my head and the crows still followed.  She looked over to see her chicks were still in the nest and I think scan for the Cooper’s hawk.  Most of the crows lost interest, but a few hung around to caw out their angst.  I couldn’t stay, I had to get to my breakfast meeting, but things seemed to be settling down and I’m sure she went back to the tree.  After a Cooper’s hawk and a helicopter, crows were merely an annoyance.

One of the chicks was scratching itself, but it almost looks like it’s trying to give a high five.  Note the large gray feathers in the nest.  Looks like the owls have been eating some pigeon.  And based on an owl pellet that Non Birding Bill near the nest, some other surprising species…but that’s for future blog entry…

The sexual tensions between pairs of red-tailed hawks was palpable today. They were either paired up on light posts or females were on the nest while a male was perched nearby keeping watching. I passed this particular nest in a ravine just off of a county road in Hastings, MN.  I got out to get a photo of the bird facing the road in the morning light, only to discover my battery dead in my Nikon D40–DOH!  I ended up hand holding my point and shoot Canon Camera and got a reasonably good photo.  I will definitely need to come back and get another photo before the leaves come out.

After my time on the Outdoor Talk show, I was driving home and chuckled when I stopped at the end of the exit for Hwy 7 off of southbound Highway 100.  Just to the upper right of the traffic signal is a red-tailed hawk nest.  It’s a long light, so I took a crappy photo with my cell phone.  I had time to scan with binos and could see a red-tailed hawk head sticking out of the nest.  I imagine this is going to be a distracting place when the young learn to fly.

We sometimes use fake owls to get the attention of passing raptors to come down to the nets during hawk trapping season but they generally figure out their fake in less than a minute. According to the description of the video, the Cooper’s hawks were nesting and kept trying to drive off the owl statue from the nest…but you would think that they would figure out the bird was fake. It also says in the description that the owl was removed because the hawks simply wouldn’t leave it alone.

I love the accipiters, but they don’t always think so clearly.

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.

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!

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.

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!

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:
