Hawk Banding Basics

Blogger is still acting strange, so the updates will come as blogger allows them--I've been working on this post from 1pm - 4:30pm trying to upload photos--grrrrrrrrrr. I think the first post should be a little note on banding and terminology before the onslaught of adventures.

I LOVE bird banding and especially hawk banding. For a few minutes, I get a glimpse into the life of different birds that make their way into the nets. This photo above is pretty much what I think my version of heaven will be when I die--beautiful fall colors, dark storm clouds behind them, a chill in the air and a bird so close I can smell it. Either I can handle the bird or the bird can handle me, I don't care so as long as those ingredients are there.

Banding migrating raptors is different than some of the other banding that you see here like songbirds or banding young birds in the nest. Like songbird banding where nets are set up around a feeding station, migrating raptors are attracted by bait--typically in the form of non native North American species like pigeons, starlings and house sparrows. What I really like about Frank's blind is that he uses only one pigeon that is heavily protected by a leather jacket. Also, the pigeon is on a tether and gets yanked out of the way of the oncoming raptors--much the same way rabbits and hares jump straight up to avoid hawks and eagles. Frank has been banding over 37--even before they started banding at Hawk Ridge. His blind is several miles away from the Hawk Ridge station and from time to time you can find some of the HR banders hanging at Frank's to relax or drop off injured birds for us to take to The Raptor Center.

Frank sometimes has nature clubs or small school groups up to his station. It's a fabulous way for kids to watch the different hunting techniques of different types of raptors. What's amazing is that some species like sharp-shinned hawks are SO focused on the pigeon that they will come right into the net with six people milling around outside the nets (that doesn't work for eagles or red-tailed hawks). The first time I ever touched a hawk was such an unbelievable rush and really solidified my interest in birds, I think it's an incredible teaching tool. Any person that visits Frank's blind never leaves without a huge appreciation and respect for raptors and many are just plain stunned saying: "I touched a hawk!"

You also get the chance to see similar sized species up close. Can you id these two different species--no prize, just for fun.

The raptors have their wings and tails measured, get fitted with a band and then are on their way. Birds are rarely with us longer than 15 minutes. When you think about what a bird will do on an average day--this is very small part of their life. These birds will fight to the death for nesting habitat, dive and kill prey the same size they are, migrate thousands of miles--15 minutes in a banding station is child's play compared to what they really do to survive. (Don't believe me, check this and this.) I think many of them leave thinking, "I put on a show of how fierce I was around those gigantic greasy primates and I got away without being eaten. Am I bad or what!"

A few things to know about raptors--first year birds (birds hatched this year) are called passage birds. Also the marks on the breast are vertical. The above bird would be called a passage sharp-shinned hawk.

Raptors that are over a year old are haggard birds. Also, the barring on the feathers tends to be horizontal. So besides having the color on the back change from brown to blue, the chest barring go from brown to rust and the eyes go from yellow to red this bird also has horizontal barring making it a haggard sharp-shinned hawk.

Females are LARGER than males. Barb Walker is holding the same species in the above photos. These are both haggard sharp-shinned hawks--can you tell which one is the female? In accipiters, the size difference is much more obvious than in buteos. I guess it's safe to say that male sharp-shins like a female with back.

Okay, hopefully blogger can fix the photo issue and more updates are coming.

I doubt that the pidgeon shares your enthusiasm for banding. Even if the pidgeon survives, I can only describe this as very selfish behavior, using animals in this way for your own personal enjoyment. And the hawk gets no enjoyment from this either. Why can't you (we) show respect for all creatures and appreciate them from a distance, without having to disrupt and control everything. You would never want or allow a socialogist to intrude into your life like this for the sake of knowledge. Don't all creatures deserve the same respect? Do you think they are there purely for your study or entertainment? Just my opinion.

Jack:
Banding any type of animal (bird, mammal, etc) is a valuable tool, for the sake of the birds, NOT a way for birders to get kicks. Hell yeah, it's fun to be that close to a real live raptor. But Sharon does this for love of the birds...all birds.
And may I remind you that we disrupt and control animals' lives just by being here and being human. We have screwed up alot of the planet and banding is just one little way we can get the big picture and maybe help. Where would bald eagles be if no one noticed that they were disappearing?
And sociologist getting into our lives? What are polls, then?
But hey, come on over to my blog and see all the fun I have at the expense of raptors.

Sharon: This has echoes of a certain blog comment from southeastern Ohio last week, doesn't it?

BTW...The ID photo...Is that a sharp shinned and a peregrine?

That's a merlin, Susan. At least I think so.

Birdchick: I have a question about hawk banding that I mentioned on my blog yesterday. Are fake birds used to lure hawks in, like at hawkwatch sites?

Laura...you're right. Well, at least I was in the correct family.

Susan Gets Native hit several nails on the head--banding is a VERY useful tool. Is it fun for me? Yes, but who said that research can't be fun?

To learn more about the value of banding visit Patuxent Wildlife Research Center:

http://www.pwrc.usgs.gov/bbl/

There are unpleasant things in my life (or in any creature's life) that are beyond control done for the sake of knowledge--mammograms scare the heck out of me.

As Susan points out we have already disrupted bird lives and must step in to try and maintain what we have and repair damage already done. I believe that eventually technology will change and perhaps banding will become obsolete, but for the moment it's what we have and a very important research tool.

As for pigeons--they are not the docile creatures that some people think--have you watched pigeons fight for a perch? They can get as violent as any bird of prey.

This site is PRO banding and I am happy to answer questions about the subject but I really do not want it to turn into a flame war. If you don't agree with bird banding, then don't read the blog--there is no one forcing you to do it.

Trollers will not be tolerated on this site and will be smartly deleted.

Laura,

I posted an answer in your blog but to answer the question about robotic lures--San Francisco Hawk Watch has been experimenting with them for years. The lures are most successful at fooling PETA members who try to release the fake birds when found.

Robotic lures do attract some raptors but at the moment are not nearly as good as a real live bird. Some day technology will catch up.

Blogger LauraHinNJ said...

Thanks for the answer, Sharon.

I like the idea of PETA folks releasing fake hawks!

I'm sure they were using live birds as lures, and guess what I took a pic of was a hawk trying to *figure out* what it was seeing, like you said. Sure looked real, from what I could see, anyway.

I would love to visit a banding set-up or at least be able to watch with a clear view what takes place. You're pretty lucky, I think.

Dumb question-

Why don't those raptors reach down and bite your fingers? Can they not bend over?

Lynne,

That's not a dumb question at all! They do bite--especially those small merlins. More on that in the next entry when blogger lets me upload photos in a timely fashion.

Banding birds is a effective tool when you have SPECIFIC reason for banding birds vs. recreational banding which is more of a hobby than science.

The trouble with banding migrating birds is that there is LESS then a 1% chance of recapturing the same bird or someone finding the dead bird with the band still placed on the leg. You have to band a lot of birds to achieve any data that is worth while.

"Where would bald eagles be if no one noticed that they were disappearing?"

Answer: When the EPA and other gov't agencies took DDT off the market which not only helped eagles but also Peregrine Falcons, Brown Pelicans, Ospreys and many other birds. Banding was just a tool to follow thier movements not the antedote for the poison they were ingesting.

Banding birds is a good research tool only if research is the main reason for banding birds. Also banding permits are extremely difficult to get and the only way you can get a banding permit is by working under someone who has a master permit. You will have to learn to ID birds by age, sex of the bird by eye color and ossification of the skull, what size of bands to use, learn how and what to measure on the bird, filling out the form and etc.. Then just maybe you will be able to get a sub permit and band birds under that master permit.

That ID photo is really striking - what a beautiful bird! I'm so glad I found your blog (through the fluffy wiles of that rabbit of yours) and now I get to learn about such a cool subject.

I just wanted to chime up with more appreciation for the great pictures! I too learn so much from your site (even if I often end up craving new binoculars).

What's up with the haters coming onto birding sites and delivering these lectures (Julie Z was hated on recently by a crazy vegetarian)? Whatever.

I can't even imagine how thrilling it would be to touch a hawk; I wish I knew someone who banded around here! I just joined our local bird club; maybe I'll find some banders there.

Thanks for the educational posts!

I understand the research/knowledge that may be gained from banding. But I doubt this research has much if any benefit to the birds. As someone above pointed out, banning DDT saved eagles and falcons, not banding. Anyone watching birds in the 1960s could see that eagles were disappearing.

Even if knowledge is gained from banding, I disagree with the underlying premise that this knowledge is somehow necessary because it is our responsibility to take care of the birds. In fact, we could do much more to help birds by just intruding less into their environments, and giving them more space (I know, a bit idealistic). It seems naive and over-confident to think that we can manage the entire planet as if it were a private zoo. I'm sure the more things we try to save, the things we will screw up.

I guess my personal disagreement ultimately commes from some voice inside that makes me see these birds as living beings, not just objects in nature to be studied or saved.

Polls? Does anyone enjoy pollsters calling at dinnertime? Do you talk to them? I know I don't. I wonder if pollsters rationalize their intrusive activities the same way we do for banding.

BTW, I don't hate anybody. And overall, my enjoyment of nature watching is way more than my disapproval of bird banding. Lighten up.

Jack,

I appreciate you sharing your opinion. I think we're just going to have to agree to disagree on this subject. Your approaching this from your perspective of birds and I'm approaching it from my work with birds and study of bird behavior. As I've said before, if you don't care for banding birds, you don't have to read this blog.

I find it interesting that of all the banding I talk about, hawk banding is touching a nerve. I talk about songbird banding weekly, we've banded osprey and peregrines in the nest this summer and I have a whole section on the site about corraling baby pelicans, gulls and cormorants for banding and there's no protest for that.

Banding migrating raptors is not about DDT but there are reasons for doing it--population and movement research, bird life span, bird health--we check crops and the breast to see how healthy birds are (things you can't see at a distance). We even have netted birds with overgrown bills which are now a subject of concern, first in Alaska and now showing up all down the west coast and starting to spread east--what is causing that?

There are some people who are for banding and some who are not. There's room for both of us on the planet and on the net.

As a bander, I'll add that much -- perhaps most -- of what we learn about banding birds is not from the 1% of birds that are recovered, but the information we gather by and during the process of banding -- age and sex ratios, fat and ectoparastite loads, etc., depending on the study being done. It's stuff that complements and supplements other types of observational research that cannot be obtained in other ways.

Hi Sharon,

I’ve been checking out your blog. Thank you for all the kind words about me.

You and NBB have to be about the most creative people I know and I am honored to be your friend. Those videos are the funniest, most informative and entertaining pieces of nature lore I have ever seen.

They should be on Animal Planet. I’d much rather watch and listen to you sneaking up on a woodcock than any of the “Jeff Corwin” types they have on. I can’t wait to see what you guys come up with next.

As for the guy named Jack who wrote in about our motives for banding, I AGREE WITH HIM. That’s why I do this banding. To me ALL life is sacred whether it be a songbird, snake, vulture, hawk or human. We all need to live in peace on this planet. In fact the thesis for my banding permit is to develop a humane method of catching raptors. (Hopefully, someday we will be using good artificial lures to gather this much needed data.) To that end, I have had only two pigeons injured in the thirty-seven years that I have been doing this. And, not one raptor of the over 3,000 that I have caught so far has ever got as much as a bent feather out of the encounter. Hardly anyone who drives a car can say that they have hit or injured only two, birds, squirrels, frogs, etc. in thirty-seven years of driving. If you drive, you are a greater danger to wildlife than my banding activities.

As for the necessity of it, a wise person once said,

“Only if you love something, you will protect it . . .

You will love it, only if you know it . . .

You will know it, only if you are taught it . . .

You can only be taught it, by someone who loves it and wants to protect it!”

After I’m gone, if I am remembered for anything, I hope it will NOT be for, “what I knew”, but rather, that, I shared what I knew.


Your Ol’ Banding Buddy,

Frank Taylor

Superb photos of the banding!
The only good thing PeTa ever did is oppose trap, neuter, and abandon for feral cats.
