Migration

I’d like to thank Mr. Mike Shaw for the generosity he extended me the past fall migration season. He was kind enough to lend me his pair of Zeiss 8×42 binoculars for the entire season. As a young biologist, I cannot afford luxuries like these binoculars. My ability to effectively document the migration to the up most accuracy was directly aided with this pair. For his kindness, I painted a scene of a migrating adult Red-tailed Hawk as I might have seen it through the lens. Thanks again Mike. I hope you enjoy this scene as much as I enjoyed my season.

An Insight into an Interaction- The Red-tailed Hawk and American Badger

by Bryce W. Robinson

TO VIEW THE SCENE IN ITS ENTIRETY, WATCH VIDEO IN FULL SCREEN

While out conducting Golden Eagle surveys in the west desert, I stumble upon many interesting and peculiar things. Car carcasses are among my favorite, but often I come upon the fauna of the land, and stand privy to their every day lives.

This past week I stopped to look at a distant Red-tailed Hawk sitting atop a greasewood, only a few feet from the ground. This behavior is a bit peculiar for this Buteo. I see many Rough-legged Hawks sitting on bushes in the deserts, but in my experience, Red-tailed Hawks tend to prefer the power poles and rock ledges. The bird sitting low caught my eye, so I investigated.

I am so happy I took the time to look. What I observed is illustrated in the above video. Again, I apologize for the quality. It is the best I could put together with my mediocre digiscoping skills. Still, I was able to capture the scene.

An American Badger- Taxidea taxus, was milling about to the left of the perched bird.  To see a badger is a treat itself, but this experience was even more special. It seemed the hawk was paying a great deal of attention to the badger. Along with the hawk and badger, a raven sat on a pole just to the right of the hawk, scolding the scene. As you can see in the video, the badger seems to be digging, and moving something about. I can only postulate what the three creatures were up to.

I think that the hawk had some success in procuring a meal for itself, only to find its prey victim to some interspecific klepto-parasitism. That is, to say, the hawk was robbed of its kill by the badger. That would have been incredible to catch, but one is only so lucky. I believe the interaction in the video is simply a Red-tailed Hawk watching a badger burry its stolen prey. The presence of the raven adds some confidence to my diagnostic.

Experiences such as this are why field work is such an adventure. I hope this upcoming week brings more adventure, as I travel the desert in search of winged wonders.

Rough-legged Hawk Feeding

by Bryce W. Robinson

 

I found this male Rough-legged Hawk the other morning. Delighted that he was enjoying a morning meal, I decided to make another attempt at digiscoping with my phone and scope. It turned out great. The video quality is what is expected out of a phone camera and scope, but it adequately illustrates the feeding behavior. It is a bit long. Some of the most interesting behavior is towards the end. If you grow tired of watching the bird consume, at least catch the last thirty seconds.

The video is also best viewed without the sound on. I added some comments for my own personal notes. My nerdy commentary and some passing vehicles may detract from the video, so I suggest lowering the volume. Enjoy!

Dark Morph Juvenile Red-tailed Hawk- Buteo jamaicensis

The past few months have been full of incredible encounters with the winged world. Recently I found a young Red-tailed Hawk perched atop a fence post along the roadside. I stopped to photograph the bird, as is my custom. I took notice of the dark coloration of the bird, which always excites me. As is possible in winter, I always get excited about dark Red-tailed Hawks and the possibility that they might be Harlan’s. I recently posted about how to distinguish between dark juvenile Westerns and Harlan’s. As I described, it is easy to see that this is a dark Western, not a Harlan’s. Still, I love the chance to see all of the diversity in the species.

What struck me about this particular bird was not anything dealing with plumage. I noticed a large clump of grass in the birds talons. Chuckling, I passed it off as a missed attempt at some prey, coming away with only a healthy talon full of weeds. I didn’t even raise my binoculars to check. Luckily, the photo tells the story. This young bird was successful in obtaining a morning meal.

It tickles me to find myself with a photo of a bird clutching its prey. The story continues, however. The bird lit off of the pole, headed away from the highway to a more secretive feeding spot. I was taken aback as a large tumbleweed flew with the hawk. I couldn’t help but laugh. In the desperate attempt to glean a morning meal, the youthful raptor grabbed more than its target, and couldn’t risk releasing the extras until it began consuming the meal.

I’ve seen some peculiar and comical behavior from young birds in the past. At the beginning of the migration season, I observed a juvenile Red-tailed Hawk grab a pine cone from a tree. It soared about for some time, regularly checking the object in its talons. One can only speculate as to what this bird was doing, but it was quite the sight, to be sure. These special instances display the character that birds possess, only becoming apparent with detailed observation, too often overlooked.
