Molting Gyrfalcon in Flight

While in Alaska this past summer conducting research on nesting Gyrfalcons – Falco rusticolus, I made many notes and observations concerning the stage of molt for each adult bird that I encountered. I’d like to share a few things that I noticed. I’m still a young student of ornithology, so none of this is new information, just a few interesting things that I noted and count as important information to retain.

First, I was interested to note the difference in stages of molt between male and female Gyrfalcons during the incubation period. The bird I have illustrated above portrays the stage at which most females molt had reached in early to mid May. Males on the other hand had either not initiated molt yet, or had just started. Needless to say, the general trend was that females were farther ahead of males and in some cases were even more advanced than what I have drawn.

Another interesting thing I noted was that this difference in molt stage by sex changed. Once the female began provisioning for nestlings, the females molt slowed as the males caught up.

I set out to illustrate a Gyrfalcon in flight to show some of my observations on molting Gyrfalcons, however creating the digital image of the illustration did not transfer some of the aspects I had hoped it would. One thing I noted concerning the body molt was that the rump was the first to be replaced. All birds in early summer had nice contrasting rumps consisting of fresh feathers. The mantle and scapulars as well as the upper wing coverts had yet to be replaced.

The Gyrfalcons in May were growing in feathers at their initiation points. In Falcons, this is P4 or 5, S4 and 5, the inner tertials, and in the tail the central deck feathers T1. This beginning stage is important for understanding the difference between hawks and falcons, and is another reason I wanted to illustrate a molting falcon

I love studying molt, and in the largest of the falcons it interests me to a great degree. Molt is costly, energetically. When you consider a large species that lives in a harsh climate such as the Arctic, it is remarkable that they complete an entire molt a year, save perhaps a few underwing coverts. Other large avian predators of the region like the Rough-legged Hawk and Golden Eagle do not do this, a fact that makes my respect for the Gyrfalcon grow evermore.

I enjoyed the exercise of drawing this falcon in flight, and adding the aspect of molt to tell a story. I plan to make this a goal of my illustration, to combine creative imagery with context that communicates ideas and facts about the chosen subject. Of course my ability to do so is still a work in progress itself, but as with learning, the process is ultimately satisfying and something I look forward to for the remainder of my life.

 

Osprey

Throughout my life I have had limited exposure to the fish hunter Pandion haliaetus. I’d like to spend more time in search of this bird, and really get to know all of it’s behaviors and characteristics. It stands true to say that there certainly is not a bird in the sky quite like the Osprey. It is remarkably unique, a fact that induces fascination and intrigue. Every time I find the Osprey, I sit in awe as it hunts the waters for its finned food.

In the past six months I have had two experiences with the Osprey. Of the two, one sits as a special memory in my mind. I was birding along the Colorado River in eastern California. I had come to see the Cibola Refuge, after hearing rumors of its birding grandeur. I wouldn’t say it lived up to its hype, however I certainly wasn’t disappointed. On my way out of the refuge, I passed a small inlet of calm water, separated from the Colorado much like an ox-bow. Catching a hovering silhouette in the golden light of the setting sun, I stopped the car to the spectacle of a hunting Osprey.

The Osprey hovers above water, watching for fish as they surface to glean their own food. Seeing a chance, the Osprey dives to the water with wings flexed back, talons stretched forward, open and ready for the grab. The osprey I watched seemed hesitant at each opportunity. It would dive, catching itself half way down as it lost lock on its fish, and the opportunity for food. It appeared as something of a dance, as the rhythm of the hover was periodically interrupted with a reverberating roll as it dove and rolled back into a hover. With the long light of the setting sun casting long shadows, all anxieties melted away as I let myself become fully involved with the hunting raptor. This instance is one of too few in my life, when my spirit settles and I am truly at peace.

 

 

Flamms in the Future

Flammulated Owl- Otus flammeolus. 11×14″ colored pencil on bristol

It looks like I will be doing some work with the Flammulated Owl again this summer. I am very excited. I’ve missed this bird. With flam on the brain, I decided to put some effort today into illustrating my first colored pencil Flammulated Owl. About halfway through the illustration I was pleased with what was turning out, but I could feel myself getting a bit tired. Instead of taking a break and finishing the bird later, I continued. Needless to say the bird turned out a bit sloppy. I’m not too upset that the illustration didn’t turn out as well as I had hoped. I will return time and time again to paint, draw, or sketch this particular owl. It is such a fun species to work with. Overall, lesson learned. If I feel tired or burnt out, it is always better to take a break rather than soldier through.
