The sturdy, broad-winged buteos tend to be large raptors with correspondingly slower movements than most smaller birds. Most of the time when I’m watching them they’re hunting from an elevated perch or soaring overhead and in neither situation do they typically demonstrate much quickness or agility.
But they can put on quite the show when they need to.
Many raptors are “sit and wait” hunters, which means they often hunt from an elevated perch instead of “on the wing” and Red-tailed Hawks are well-known for this practice. An elevated perch provides good views over a large area and no extra energy need be expended in flight while looking for food. Typically these birds will use the same productive perch repeatedly over long periods of time, which presents a challenge to the photographer – poop (hereafter referred to as “whitewash”). Whitewash consists largely of crystalline uric acid (it’s more complicated than that but I’ll try not to stray into a discussion of the functions of the cloaca), which tends to be bright white. That whitewash can create some aesthetic and ethical conflicts between a “natural shot” and an image that has been “Photoshopped” to death, primarily by use of the clone tool. Many photographers routinely clone out whitewash and/or droppings and I’ll admit that I’ve done it before, but for me it’s an ethical dilemma because I much prefer to leave my images as natural as possible since I consider myself to be a “nature photographer”. In fact, right now I’m struggling with a series of Horned Lark images that I really like, but there’s a large, fresh and very conspicuous dropping right in front of the birds foot that most would find distracting. I could clone it out but every time I looked at that image I would know what I’d done. Canon 7D, 1/4000, f/5.6, ISO 640, 500 f/4, natural light, not baited, set up or called in A couple of days…
I’ve said before how much I prefer the very dark Farmington Canyon Complex rocks on Antelope Island as perches, over the bright white Tintic Quartzite rocks found on the northern part of the island. This juvenile Red-tailed Hawk made my morning last month when it chose just such a rock to hunt from. I always enjoy it when I can get multiple shots of some interesting behavior or action in sequence. To me it’s almost like a very slow motion video and though it may include a few images that aren’t perfect individually I think that collectively the photos gain value as a group for what they illustrate – the whole can be greater than its parts. 1/2500, f/7.1, ISO 400, 500 f/4, 1.4 tc, shot from pickup window, natural light, not baited, set up or called in Photographing take-offs is always a challenge. The bird may just sit there for a half hour or longer but when it happens it’s quick and easy to miss. 1/2500, f/7.1, ISO 400, 500 f/4, 1.4 tc, shot from pickup window, natural light, not baited, set up or called in You also need to be concerned about what direction it will go and if you’re too close (it’s easy to clip wings if you are) or too far away (which shows less detail). Those with zoom lenses have an advantage over me because they can quickly adjust their focal length to whatever they want within their zoom range, while the only option I have is to attach or detach my teleconverter, which is cumbersome and takes time. …
I’ve always found it fascinating to watch these little falcons eat. A gruesome experience to be sure but so much more interesting than observing a raptor such as an owl who simply swallows its prey whole. And if you watch carefully there’s a whole lot more going on during the process than first meets the eye. Kestrels can be pretty picky eaters. I’ve documented in another post on this blog that they often refuse to eat the intestinal tract of their prey and deliberately discard it. Kestrels, like other raptors, eject pellets of indigestible materials like fur, feathers, chitin and bone. All food that is swallowed first goes to the crop. From there the usable food continues on to the stomach but the indigestibles stay in the crop, are formed into a pellet and regurgitated roughly 23 hours (in the case of kestrels) after the meal was consumed. Canon 7D, 1/800, f/7.1, ISO 640, 500mm f/4, 1.4 tc The kestrels I’ve watched eating voles and mice typically eat the brain, decapitate the rodent, then go for the soft internal protein rich muscles and other organs (discarding the intestines). Since kestrels tear their prey into bite-sized pieces they can pick and choose what they actually swallow. Canon 7D, 1/400, f/8, ISO 640, 500mm f/4, 1.4 tc Pellet expulsion can be difficult and traumatic as I’ve documented elsewhere on this blog with Northern Harriers and I suspect that’s one of the reasons that kestrels try to avoid swallowing as much fur as possible. When opening up the body cavity they often get a beak-full of…
