Road Trapping

Yesterday, I got a chance to experience "road trapping," which involves taking our raptor banding show on the road. Essentially, we drove around until we spotted a raptor. We chucked a trap out of the window of the car, waited for a few minutes to see if we could catch the bird, and then banded it right out of the trunk of the car.

We spent the entire day driving around the Davis, CA, area. However, time flew by as we were constantly stopping and occasionally banding some incredible birds. Three of the six birds we banded yesterday were American kestrels, the charismatic little falcons that I have come to love this year.

Female American kestrels are aged by the final black bar on their tails. In this case, it was an adult bird because the last black bar is so much thicker than the other bars.

We were not successful in catching every bird we set the traps out for. Even so, just getting a chance to see some of these unique raptors was worth the trip.

The highlight of the day, however, was banding three adult red-shouldered hawks. There is a theory the other GGRO interns have developed that any black-and-white bird (especially if there is a hint of red) will automatically qualify as one of my favorites. Recent examples include pigeon guillemots, black phoebes, and California condors. Thus, these beautiful birds immediately won me over. So much so that I am writing in an uncharacteristically gushy way about them. But I'm putting science aside for this entry, because these birds are just plain amazing. See for yourself:

Red-shoulder #1.

Look at the black and the red and the white. Just look at it! Wow!

I demonstrate why this bird is called "red shouldered."

Are you seeing this bird? It's so cool!

Red-shoulder #2 was much redder on the body. Do you see this bird? Do you see how beautiful it is?

This is another shot of a red-shoulder looking incredible.

This is red-shoulder #3, caught about 27.3 seconds after red-shoulder #2.

Some red-shoulders have particularly prominent hackles (feathers on the back of the skull), giving them a spiky-headed appearance.

So, here's the deal. I like birds (obviously). That being said, I like to think of myself as a scientist, biologist, what-have-you-ist. I like to take an objective perspective of my work and not resort to constant "ohhhhhhhh those birdies are soooooo cuuute!!" gushiness. That's not why I'm motivated to do what I do. However, I think it is important to take a step back every now and then and acknowledge the simple fact that these creatures are amazing, beautiful, incredible. Yesterday was an experience in research, but more importantly, in was an experience in awe-stricken appreciation.

Banding 9/7: Superstitious

Some of the volunteers in the GGRO banding program can be a little superstitious about the way things run in the banding blind. Yesterday, for example, as we got the blind set up for the day, I placed all of the banding tools out on the table in anticipation of the processing of a raptor. I was gently informed, however, that this could totally jinx our ability to catch a raptor in the first place. Sure enough, we spent the first three hours that morning staring at a birdless landscape.

Finally, my sight leader took it upon herself to put all the tools back in the drawer from whence they came. Five minutes later, we caught our first (and only) bird of the day, a male American kestrel.  I'm learning so much about science.

Kestrels are one of the few raptors where males and females show distinctly different plumages. In this case, the male shows silvery/blue wings whereas the female is rusty with black stripes across the back and wings.

Female American kestrel tail: "tiger" striping all the way across. (We banded a female AMKE on Thursday - pretty cool to see both sexes up close within a couple days of each other).

First Day in the Blind

Yesterday, the GGRO banding-man-in-charge, Chris, took fellow intern Anna and I up for an "intern practice banding day." Given that it's pretty early in the season, we weren't really expecting to band any raptors. However, a randomly sunny day combined with a nice wind led to an exciting first day in the blind.

There are four blinds in operation around the Marin Headlands. We banded at the "Slacker" blind (named after the name of the hill, not the laziness of its users), from which we had a beautiful view of Hawk Hill, Point Bonita, and the Pacific Ocean, as well as much of the rest of the Marin Headlands. Most of our morning was spent repairing nets and making sure everything was in tip-top shape, but by noon, we were inside the blind, waiting for some raptors to appear. Here are some of the highlights that came to follow:

-Prairie Falcon: One of the most elusive birds of the Marin Headlands, the prairie falcon is seen by the hawkwatchers an average of four times per season, and banded an average of twice per season. How amazing would it be if that were the first bird I banded out here? Spoiler alert: it wasn't. However, I got an amazingly up-close look as one stooped right into the trapping area. It was quick, but we identified it as a prairie falcon without question. This might've been my only chance to see this bird all season - amazing!

-Red-tailed Hawk: Our first successful catch was a juvenile red-tailed hawk. Even before taking measurements, we could tell that she was a female based on how hefty she was (female raptors are larger than their male counterparts). Even more interesting was the fact that she was a rufous-morph, a rarer version of the typical red-tailed hawk. We came to this conclusion based on the heavy, dark streaking on her upper breast, and the cinnamon hue to her tail.

Almost immediately, I learned a valuable lesson in large raptor handling. GGRO handles raptors differently than my previous experience at Hawk Ridge, and as I was adjusting my grip, one of her legs came free. The next thing I knew, four sharp, hawk talons were embedded in my arm. Chris was a champ, as he pulled those strong toes apart, but it was certainly more than a sting. In fact, I'm a little disappointed that the scars left behind are so wimpy - they don't reflect the amount of pain a wild raptor's talons are capable of. Obviously, I came out alive and it was a great lesson. I will certainly be considerably more cautious handling raptors from now on.

I then got to experience the processing of the hawk, as I took all of its measurements, applied the band, and recorded all of the data. This took a bit of time, it being my first bird, and I'll be working to increase my efficiency with this stage of the process to decrease the amount of time the wild bird has to hang out with me in the blind. Afterwards, we took her outside for a photo-op and released her into the wind.

Here I am with the first raptor I banded in California. Not a bad start! (Photo credit: Anna Stunkel - also the next one).

I'm attempting to show off this bird's wing, but the wind was making that challenging.

-Four more red-tailed Hawks: While I was processing lady red-tail, we were being taunted by four other red-tailed hawks outside the blind. They circled around, came close to the nets, and then flew back up again, over and over and over. In fact, one actually perched on one of our poles for a record-breaking 18 minutes. Chris said that this is typical kestrel behavior, but you rarely see a buteo act this way. Very interesting.

-American Kestrel: Towards the end of the day, we caught our second bird, a hatch-year, male American Kestrel. The males are distinguished by their silvery-blue wing color, and solid tail with a bold black stripe. We aged it as a juvenile because it had stripes all the way up its back (instead of only partway as we would have seen in the adult).

The girls I work with keep going on and on about how adorable kestrels are. I wonder how cute they'll think it is when they see one attacking its prey.

American kestrels are falcons, same family as the peregrines. I find myself partial to falcons, so it was pretty cool to see this bird up close. Anna did the processing this time as I kept an eye on the nets (and another kestrel managed to elude us). When Anna was done, I handled the bird as well. Red-tails and kestrels represent the two size extremes of birds we'll be handling this season, so it was nice to get a feel for both ends of the spectrum. Afterwards, I let him go too.

By the time our kestrel was flying off into the hills, we had to start cleaning up and head back down the hill. Considering we were expecting to see very few birds, I would consider it a very successful day. A great first experience banding at GGRO.
