Gyrfalcon (Falco rusticolus) Plate

My friend Kenneth, a Gyrfalcon researcher in Norway, is perhaps the most enthusiastically obsessed Gyrfalcon lover I know. I really appreciate his passion for the bird. Next week he is traveling to Salt Lake City for the Raptor Research Foundation’s annual conference. He asked me to paint a Gyrfalcon portrait for him, so I decided to take the opportunity to illustrate some perched birds to populate the plate I’ve been putting together. I going to produce some giclee prints of this plate, but I’m limiting it to 20 prints. If you like this image, and would like to purchase a print, it is available in the shop!

It’s taken me some time to paint birds that I’m pleased with enough to put into plate form. I’m still a bit at odds with these birds, but I think the above image best fits what I’m going for in creating the plate. My next step will be to paint some different postures and explore which best fills the gap in understanding the different positions and appearances that a Gyrfalcon may take on, in varying conditions. Additionally, the plate needs multiple different in flight postures, and some other age and plumage morph descriptions. Progress has been made either way, and I’m excited!

Below is the painting that I did for Kenneth, as it will look to him. I’ll be traveling to Salt Lake City myself, with this painting alongside me. Thanks for the opportunity Kenneth!

Orange-breasted Falcon Plucking Prey

by Bryce W. Robinson

 

For the Orange-breasted Falcon whose diet consists primarily of avian prey, to eat requires a great deal of work. First, the birds must capture a food item. They specialize in above canopy surprise and pursuit capture, a technique that blends a bit of skill and luck. When the two align and the bird finally captures a meal, they then must prepare it. Falcons prefer to ingest little amounts of feather from their prey items, and thus need to efficiently remove the extraneous feathers to access the muscle. To remove these feathers, they pluck their prey nearly clean. Plucking can be beautiful, as I found with the Orange-breasted Falcon in the video above as it prepared a Great-tailed Grackle. Perched on a limb high overlooking a deep river valley, the bird plucks. The observer can easily recognize the bird’s technique of rip and flick, as it efficiently carries out its daily ritual and feathers calmly drift away in the hot Central American air.

Published in Western Birds: First Record of Breeding Eurasian Barn Swallows (ssp. gutturalis) in North America

My friend Luke DeCicco and I published a paper in the Western Field Ornithologists journal Western Birds that details an observation I made during my last hours of the 2016 field season in Nome, Alaska. I happened upon four recently fledged Barn Swallows being provisioned by two adults, that were obviously white-bellied Eurasian birds. I couldn’t spend much time with them due to my departing flight, but I did my best to document everything in haste. The flight back to Anchorage was fun, as I sat there with my mind buzzing thinking of how to report this observation in the literature.

I asked my friend Luke be on the manuscript for a few reasons. First, Luke had identified a white-bellied bird in the same location (Nome DOT utility yard) a few days prior while we were loading our storage container. As such, I had my eyes open while traveling through the area when I spotted the birds being provisioned. Without his initial observation, I may have been effectively asleep at the wheel and may have missed the birds entirely. Birding was not the reason I was in the utility yard. Second, Luke has an impressive handle of the birdlife of Alaska, along with the connections necessary to expeditiously investigate the historical status of the species in the state, and to assess the potential that this record was indeed a first. In the end, he brought forward and engineered the aspect of the paper that is perhaps the most useful, an update on the status of Eurasian subspecies in AK, along with a summary of records of vagrant subspecies. The result is an article that will be very useful for folks in the future as they put their own observation into context. I feel really fortunate to have Luke’s contribution to this publication.

This publication represents a few firsts for me. Primarily it represents crossing a threshold in my career, as it is the first publication of mine where I have incorporated my passion for ornithological illustration. I painted a rendering of the differences between the subspecies discussed in text in the form of museum specimens. I’m very pleased with the figure, and I’m excited to continue to make illustration integral in my work.

The paper is worth a read for anyone interested in Alaska’s birdlife, and bird distributions in North America.

Sulphur-rumped Flycatcher (Myiobius sulphureipygius) Foraging in the Dark Understory of Southern Belize

by Bryce W. Robinson

I’ve been in Central America for nearly two months, and I haven’t had the time or energy to post any stories, images, or illustrations from my experience thus far. There are of course many stories to tell.

Flycatcher (Family: Tyrannidae) diversity in Central America is very high. Getting to know this diversity has been an excellent challenge. I’ve had a lot of luck seeing most species that I might encounter in Belize, and among my favorite have been the small and endearing flycatchers of the rainforest, such as the Sulphur-rumped Flycatcher (Myiobius sulphureipygius).

I’ve seen the bird only a few times. It sits low in the understory of the rainforest, near relatively open areas and perch hunts for insects. Its large eyes are obviously engineered to spot prey, and it tactfully watches and waits until it sees an opportunity. This can be for a minute or more.

These birds don’t seem to mind my close proximity when I’m watching and photographing, and seem only focused on its task of procuring food.

Contrasting this seemingly patient and calculated technique with another small flycatcher, the Ruddy-tailed Flycatcher (Terenotriccus erythrurus) has been enlightening. From what I have observed, these birds are constantly making attempts at captures, and hardly sit still for more than a few seconds. It’s difficult to tell if these many attempts are all successful, because the insects it is after are much too small to observe at any distant.

Hopefully I’ll be able to capture both foraging techniques on video. There’s always another way to describe the behavior, whether it be writing, illustration, or video. I’d like to blend all three for these birds.
