Kestrels Perch In The Oddest Places
American Kestrels are primarily perch-hunters and they’re quite flexible in their choice of perches.

Barn Owls On Unnatural Perches
It’s been a while since I’ve seen any Barn Owls out and about and I’m thinking they won’t be flying again during daytime until at least next winter so I decided to bid them adieu for the present with one last post for the season. I generally prefer my avian subjects on natural perches but Ingrid Tayler’s affection for birds on man-made perches in the urban landscape is beginning to instill in me a little more flexibility. Perhaps it isn’t too late for some new tricks from this old dog… 1/2000, f/7.1, ISO 500, 500 f/4, natural light, not baited set up or called in At Farmington Bay WMA there are numerous signs posted directing hunters to where they can hunt and where they cannot and those signs are favorite resting spots for hunting raptors. When I come across an owl on one of these signs I’ll typically drive on by unless there’s a possibility for take-off shots but I made an exception for this one despite the less than ideal light. 1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited set up or called in Another favorite perch is this kestrel nesting box at the top of a hill. From this elevated vantage point the birds can hunt visually over a large area without expending the energy required for flight – a significant advantage in the depths of a long, cold winter when calories are at a premium. This owl looks like it might be wary of me and about to fly, but it isn’t. It was calmly…
Why The Killdeer Doesn’t “Perch”
More than half of all bird species (5000+) are classified in order Passeriformes and referred to as passerines. Passerines, sometimes known as perching birds or less accurately as songbirds, have four toes – three of them directed forward and one toe directed back. This arrangement allows for stable perching on structures such as small branches and herbaceous stems because the hind toe is opposable to the others (much like our thumbs are opposable to our fingers) which allows “grasping”. Interestingly, the tendon/bone anatomy of a passerine causes automatic closing of the foot (grasping) when the leg bends – such as when it lands on a typical perch. This arrangement also allows passerines to sleep on a perch without falling off. Here you can see the typical “three toe forward, one toe back” arrangement on this Savannah Sparrow that allows passerines to grasp narrow perches like branches or wires and remain stable on them. Animals without something like this toe arrangement would be “walking a tightrope” but these birds have no problem with it. Maintaining stability on a perch such as this would be virtually impossible without the ability to grasp, particularly in a breeze (this is a Loggerhead Shrike). This shot of a juvenile White-crowned Sparrow gives us a better look at all four toes. One more look at the opposable rear toe, this time on a Western Meadowlark. Ok, now to my point. Many birds that do not typically “perch” (with exceptions) are waterfowl and shorebirds. The Killdeer is a plover but because of the habitats…
Perched Coyotes
A perch (when it’s not a fish) is defined as “a roost for a bird” or “a prominent resting place”. Most of the perched critters I photograph have feathers, but not all of them. Many mammals like to perch up high on rocks, small hills or other natural or man-made structures in order to have a better view of their surroundings. In the case of predators, like coyotes, they often do so while looking for prey. Some small mammals (prairie dogs and ground squirrels, for example) often elevate their position in order to watch for predators. 1/1000, f/6.3, ISO 640, 500 f/4, 1.4 tc Getting a clear, relatively unobstructed shot of a coyote can be very difficult because of the types of habitat they tend to prefer. But sometimes I don’t think it’s necessary to get them in the clear. This coyote was hunting voles just as the sun was coming up. It deliberately placed itself in the shade of the sunflowers to be less easily seen as it watched and listened for rodents. Even though only about half of the coyote is visible, I still like the shot because it shows behavior and I think the sunflowers add a nice touch. There’s just enough light in the right eye to make this work for me. 1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc But when the coyote alone is the primary subject of the image, a relatively clear view of the entire animal is often preferred. That’s when the photographer can take advantage of the…
The Timelessness of a Buffalo Chip Perch
The American Bison is a relative newcomer to North America, having migrated from Eurasia over the Bering Straight about 10,000 years ago. As is common knowledge they once roamed in massive herds across most of the continent until commercial hunting and slaughter reduced their numbers to a few hundred by the end of the 19th century. 1/500, f/6.3, ISO 500, 500 f/4, 1.4 tc Today a herd of approximately 500 animals roams free on Antelope Island and that many large animals produce a lot of poop – commonly referred to as “buffalo chips”. Those chips are all over the island – like small dark islands in a sea of prairie grasses and tiny flowers and they’re tempting perches for a variety of bird species like Horned Larks and Meadowlarks. But this past week I was able to catch some larger birds using them as perches. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc In the spring some of the shorebirds and wading birds come up from the shore of the Great Salt Lake to higher ground on the island for their breeding activities – Long-billed Curlews among them. It seems that the added height of only a couple of inches provided by the chip is enough to significantly improve their view of the landscape for potential predators and also to help them keep an eye on other curlews in the area – there’s a lot of fighting and mating activities going on this time of year. To some viewers such a perch may have no aesthetic draw but I’m…
Lamenting the Loss of a Favorite Perch
This was a perch I had a love-hate relationship with for almost four years. It was a small, very old and sun-bleached snag along the road down unit 1 at Farmington Bay Wildlife Management Area. I loved it because American Kestrels liked to use it as a hunting perch, it was close to the road, not too high and it was natural and photogenic. I hated it because it was on the east side of the road (I could only shoot from the road in my vehicle – open the door and the kestrel skedaddles) which meant that I was usually shooting into the sun in the morning which is my favorite time to photograph birds. Back-lit kestrels are generally not a pretty sight… That road down unit 1 is closed for the nesting season (March through September) and I was very disappointed to see on my first trip down the road this fall that the snag was gone. It may have fallen down on its own, been removed by refuge managers (which I doubt) or perhaps it was vandalized – I just don’t know. But I will miss it, as will the kestrels I’m sure. Avian photographers on this continent are well aware of how difficult this species is to get close to – they’re very skittish and almost never allow a close approach for photography. That changes in mid-winter when it’s very cold. They simply are much more reluctant to fly when it’s that frigid and the photographer can occasionally get quite close to them, especially when shooting from a vehicle. But most nature photographers…
