Fall Fest

The town of Cable was hopping last weekend during our 16th annual Fall Festival. Not one to miss out on the fun, Aldo made a few appearances in front of the Museum to meet festivalgoers and appreciate the classics in the car show.

Aldo was raised at a rehabilitation center and imprinted on his human caretakers. He learned to associate with people rather than other kestrels, so he cannot be released back into the wild. It also makes him the perfect ambassador at a crowded festival. He can handle noise and activity better than the other birds, but he still has his limits. After about 15 minutes of watching the crowds, he started to spread his wings to tell me he was ready to leave. I brought him back to his mew to rest and watch activity from his new window.

Jess Grease

This week I noticed Aldo’s jesses, the leather straps that hang from his legs, becoming more and more stiff. He seemed to notice, too, when he stamped his feet to move the leather to a more comfortable position. It was time to apply an oil to condition the leather. Luckily falconry suppliers make a conditioner specifically for this purpose: jess grease.

To condition the whole length of each jess, I need to remove the leash that binds the pieces of leather together and secures him to my glove when he is out of the mew. That means that if he tries to fly away during this process, he is more likely to escape. In case he gets away from me, I choose the smallest room with the lowest ceiling and fewest perches: the staff bathroom. Applying the jess grease is easy and I simply rub it in with my fingers. The grease will sink into the leather to keep it supple and waterproof for a few more weeks.

 

Water

With her confidence growing, Carson has been taking each new step of our training like water off a duck’s back.

Like ducks, all birds have to work to waterproof their feathers. By rubbing their head and beak in an oil gland at the base of the tail, birds spread the water-repelling oil to all of their feathers while preening. Drops of rain will bead on the surface of the feather, rather than sink in, and roll right off. Waterproofing keeps the fluffy down feathers dry underneath and maintains their insulative qualities. The bird stays warm and dry even through heavy showers.

From beak trimming to meeting groups of visitors at the Museum, Carson doesn’t seem to mind. She is still eager for training even after these mild stressors. Just like waterproofing takes some effort to maintain, building our relationship and Carson’s confidence in new situations took time. But we are seeing the rewards now as she takes everything in stride, like water off a hawk’s back.

Time for a Trim

Each time I brought Carson the Red-tailed Hawk outside last week, I had to cringe a little. Her beak was overgrown and not only did it look bad, it was also getting in her way. It was so long that a piece of meat occasionally got speared by the hook and she had trouble getting it off. It was time for a trim.

Her last trim, or coping, was 10 months ago when she visited The Raptor Center last fall. While Aldo the American Kestrel’s beak grows so fast he needs a trim every 2 months, Carson’s beak grows slowly and requires less maintenance.

Coping a hawk beak feels like a piece of cake compared to a kestrel. Kestrels, as falcons, have specialized notches in their beaks that need to be shaped. Hawks conveniently have a smooth-shaped beak and I only had to concentrate on shortening the hook. We finished quickly and brought her back to her mew to enjoy half of a rat with her smooth, shortened beak.

Unlikely Relatives

In a raptor program last week, a young man asked why Aldo looks more like a parrot than a hawk. It seemed like an odd question and I wasn’t sure how to answer it. ┬áLater that night I put Google to work and found that his observation was actually very astute.

 

Falcons have long been grouped with hawks and eagles due to their similar predatory lifestyles. On the outside, just about the only thing they share with parrots is a sharp, curved beak. This tool is used for very different purposes: parrots crack hard seeds with their beak while a raptor’s hook is used for tearing meat. But researchers recently made a surprising discovery by studying what we can’t see with the naked eye: DNA. By comparing these building blocks in a variety of birds, they found that falcons actually share more genes with parrots than they do with hawks. Falcons and parrots are, in a way, long-lost relatives.

Al Batt, birder and storyteller, said last week at his evening lecture that he learns the most when he answers questions. That seemed a little backwards to me, but I realized exactly what he meant when I thought of this question about parrots. The inquisitive visitor saw similarities between species that I wouldn’t have noticed. It forced me to look at Aldo from a new point of view, trigger new questions in my mind, and learn something new along the way.

 

 

 

 

Rouse

It is officially one year since I rolled into Cable and presented a raptor program with Aldo and Carson on my first day of work at the Museum. It has been amazing getting to know these birds more closely and see their progress over the last year. Carson the Red-tailed Hawk has come the farthest her training. A year ago, she ran away from me when I got too close with the glove. Today she ran toward me before I was even ready to start. She stepped on my glove (and got a chunk of rat for her effort) and we went outside to get weighed on the scale and enjoy the sun. A chipmunk rummaging through the garden piqued her interest. Every time I moved, she craned her neck to keep her eye on the little rodent, so we stayed outside to take advantage of the free entertainment. Naturalist Intern Bethany even snapped this photo as Carson roused and shook out her feathers to get comfortable. It took time – and a lot of quail, mouse, and rat tidbits – to get to this point, but seeing Carson rouse on glove is all the reward I need to know that the effort was well worth it.

Carson’s Molt

All of the birds have started their annual molt in the last few weeks. With thousands of feathers to replace, the process can take months. If all the old feathers fell off at the same time, the bird would be quite helpless! Instead, wing and tail flight feathers are replaced in a specific order so the bird only misses one or two feathers at a time and can still fly.

I found a beautiful red tail feather that had been shed in Carson’s mew last week. This week, I noticed she had an uneven tail: the replacement feather is starting to grow in! The short feather you see in the photo is her first new tail feather. One by one, she will replace each feather in the next few weeks.
