Another month, another raptor: the Peregrine Falcon, Falco peregrinus.
We’ve been learning a lot about Gyrfalcons recently because of my work with the Gyrfalcon Conservation Project, but there are many other raptor species on the Seward Peninsula of Alaska. Golden Eagles, Rough-legged Hawks, Northern Harriers, Short-eared Owls, and Peregrine Falcons also call this place their summer home.
Not that long ago, the Peregrine Falcon was listed as an endangered species after populations plummeted from the negative effects of the pesticide DDT. After the banning of DDT, the Peregrine has since been de-listed and can now be found breeding in many major North American cities.
It’s great to find them swooping around their traditional breeding grounds way up north, doing what falcons do.
If you keep up on the Wild Lens blog, this months raptor photograph will come as no surprise: the Gyrfalcon.
For the better part of four weeks I have been studying the worlds largest falcon for The Peregrine Fund and Boise State University’s Gyrfalcon Conservation Project. We now have three nest cameras successfully installed at various Gyrfalcon eyries on the Seward Peninsula in northwest Alaska.
These nest cameras are collecting valuable information on the quantity and diversity of prey adult Gyrfalcon are bringing to their nestlings. This information will help us researchers determine what affects climate change is having on Gyrfalcon diet throughout the breeding season.
All of the previous Raptor of the Month photographs, as well as previous 52-week blog photos can be found at the Wild Lens blog or on Flickr.
Standing a whopping 3-feet in height, the tallest owl in North America inhabits the northern boreal forests and western mountains. Feeding on mainly small mammals, Great-grays are perhaps most famous for a hunting technique termed “snow plunging.”
While the ground of the Wallowa-Whitman National Forest of eastern Oregon was clear of snow, I still had the privilege of watching this Great-gray Owl make several hunting attempts; each time plunging into the grassy meadows of a mature Ponderosa Pine forest.
While I never observed the owl successfully capture it’s prey, it was amazing to watch the bird repeatedly plunge to the ground, seemingly unaware of my existence.

While I was hoping to highlight a different raptor species every month for this ‘raptor photograph of the month’ 2014 project, this Ferruginous Hawk was just too cool to pass up (and quite honestly I didn’t have anything better to replace it).
I had the chance to briefly return to central Utah at the beginning of March. I made a quick stop by my favorite Buteo location where I photographed January’s Ferruginous Hawk and was not disappointed. The Rough-legged Hawks were now mostly gone and the agricultural fields consisted of mainly Red-tails and Ferruginous Hawks, although a few Bald Eagles could be seen in the distance.
Someday I hope to capture this species with a more interesting background than just a plain blue sky. And I promise next month will feature something besides a Ferruginous or Rough-legged Hawk. Until then, enjoy all those birds that are passing through on migration or returning to their breeding grounds. April is one of the best months to go birding.

Our raptor for February 2014 is the Rough-legged Hawk. This time of year always makes me a bit sad as I know the Roughies are making their way poleward, back to their arctic breeding grounds. While some birds will stay on their wintering grounds into April, we won’t see most of these birds again until October or November of 2014.
This adult male was captured and banded using a mouse-baited bal-chatri trap on February 17. In addition to banding this bird, several morphometric measurements were taken to help scientists better understand the differences between males and females of the species.
Below are a series of three photos detailing the wing and tail plumage of this ATY (After-third Year) adult male Rough-legged Hawk.

Well I couldn’t stay away for too long.
I gave up on the idea of continuing the 2013 52-week project into 2014 as it would have been too big of a commitment, but I wanted to do something in 2014. Instead of posting a bird photograph every week, I’ve decided to post my best raptor picture at the end of each month.
January 2014 features an adult Ferruginous Hawk (Buteo regalis), the largest hawk in North America. This individual can be identified as an adult based on its ‘rusty leggings’ and upper-wing coverts, which are just barely visible on the top-side of the bird’s left wing. Juveniles generally lack the ‘rusty leggings’ of adults, are much whiter underneath, and have less rufous in the upper-wing coverts.
Below is a photograph of a juvenile Ferruginous Hawk for comparison.

Ferruginous Hawks are an uncommon open-country hawk whose range is mostly confined to western North America. While they are a species of Least Concern in the United States, they are considered Endangered in Canada.
Here we go: The final post of this 52-week project and I am so glad to be in western New York for this one!
The number of Snowy Owls I have seen along Lake Ontario in New York has been staggering. One day I saw 3 along the lake, each in a different location. Another day I saw 2 flying around together in my hometown of Sodus. It’s been great.
One thing I’ve been struggling with however: the influence of photographers on the stress levels of these birds. I try my hardest when photographing to disturb the birds as little as possible, but I’ve noticed other photographers acting seemingly oblivious to these rare birds they are photographing. Some try to just walk right up to the birds, and the owls end up flying away, exerting unneeded energy during the exact time of year when they are stressed out the most from limited food resources and cold weather. I know photographers are looking for that one great shot, but we need to be aware that we may be influencing these birds in a negative way if we’re constantly approaching closely them to take pictures. Sorry for the diatribe, but had to get that off my chest. Lets all make a New Year’s resolution together: to be more responsible nature photographers.
Back to this 52-week project: For the past year I’ve taken and posted a bird photograph every single week (didn’t miss a week). But now the year is over and the question remains: do I continue this project into 2014? It’s been a lot of work and part of me wants to take a break. Maybe I can continue it in a slightly different way? Any ideas out there?

Turns out there are raptors in New York City too, and from my limited observations they live a pretty cushy existence.
Most folks, even non-birders, know about the Red-tailed Hawks of Central Park. But while visiting the big city last week I made a visit to the lesser known, but equally impressive Prospect Park in Brooklyn to check out the bird diversity.
While watching gulls and ducks around the shores of Prospect Park Lake, I saw three separate Red-tailed Hawk hunting attempts in little over an hour. Two of these were successful.
The first successful attempt involved an unlucky immature Ring-billed Gull out in the center of the ice. The hawk picked at the carcass for only a few minutes before attempting to fly it to shore. It dropped the carcass to the ice before making it all the way in, and did not return to feed again.
The second successful hunt involved a different Red-tailed Hawk (banded with an aluminum ring on the separate leg from the other hawk; both were banded). The hawk flew from a tree and made a b-line across the lake, hitting a lone immature Northern Shoveler on a small unfrozen piece of water near the shoreline. The duck never saw the hawk coming.
An unlucky Northern Shoveler.
I snuck around the lake to take this weeks photo as the Red-tail plucked at the duck after dragging it to shore. After 10 minutes or so, the hawk flew off out of sight and I went to inspect the carcass. The hawk had only eaten part of the brain and spinal column of the duck, leaving the rest untouched.
When animals have an over-abundance of available food, they will kill more often and only eat the richest pieces of meat. This appears to be the situation for the hawks of New York City. They have a copious supply of birds on which to prey, most of which are quite tame from their constant interactions with people.
Great to see some raptors adapting quite well to city life.
I made an unofficial rule at the beginning of this 52-week project that I wouldn’t use the same species two weeks in a row. Well we can throw that one out the window in favor of getting close encounters with my favorite bird species two weeks in a row. Totally over it.
I was lucky enough to trap this adult male Rough-legged Hawk near Grand View, Idaho on Sunday. Definitely the coolest bird I have ever had in the hand. The whole experience felt a little surreal, especially knowing that this bird had just spent the summer breeding in the Alaskan or Canadian Arctic, and now I was holding it right here in Idaho!
Hope to catch more of these guys when I return to Boise in the beginning of January. Maybe an adult female next time!
It’s no secret that Rough-legged Hawks are my favorite bird, but they have continued to be my “nemesis photograph bird” ever since I acquired my Canon 7D in the summer of 2012. No longer.
I had several better photographs of different species I could have chosen for this weeks photo (including some Golden Eagle shots), but I couldn’t pass up the opportunity to post a picture of a roughie. If I’m lucky, maybe all of the remaining photographs in this 52-week project will be of Rough-legs. I know I can get better shots than this one.
On a side note: while it is impossible to say for sure, this is likely an adult male given the almost complete absence of a belly-band. Adult males can have several distinct subterminal tail bands, but this bird seems to just have one. Hard to say for sure…
