One of the reasons I like to see iridescence in Black-billed Magpies is that it brings out detail in those areas of the deep blacks where you normally don’t see any. Flight shots are inherently more difficult than static shots but ironically I find it easier to get the iridescence to show in flight than I do when they’re perched.
The Wilson’s Snipe is an odd little shorebird, both in appearance and in some of its behaviors. Though common, they’re also elusive and shy so over the years I’ve been able to get very few quality images of them. But my luck with the species changed for the better three days ago.
This past summer I photographed several active Ferruginous Hawk nests and was impressed by their size differences and the variation in elevations of the nests from the ground. Each of these nests was photographed in southwest Montana in June of this year.
Northern Harriers are occasionally known to play but it’s something I’ve seldom seen. Harriers are normally all business as they pursue simple survival in a harsh and unforgiving world but a week ago today I watched and photographed as one of these hawks had some apparent “fun”.
Handedness is a preference for using one hand (or limb) as opposed to the other. It’s a phenomenon many of us associate strictly with humans but other vertebrates can also show handedness, including birds. For example, many parrot species have a strong and consistent preference for using their left foot when bringing food to the beak.
Based on my own observations in the field I believe that Short-eared Owls may also display handedness.
The seriousness of confrontations between Northern Harriers varies with the situation. Conflicts over food, especially during harsh winters, can be intense and dramatic but they often seem to spar with each other just for the “fun” of it. I’ve often seen and occasionally photographed both extremes of aggressive behavior.
Though Short-eared Owls are one of the worlds most widespread owls, the species is highly dependent on the density of its small mammal prey, voles in particular. Since vole populations fluctuate wildly, Short-eared Owls show significant local variation in numbers and reproductive success from year to year.
Yesterday morning I saw my first Bald Eagle of the season at Farmington Bay. It was too far away for even mediocre images but it was there! We have a small number of resident eagles in northern Utah but those few birds normally don’t hang out at Farmington this early in the season so I’m not sure if it was a wandering resident or an early migrant. Either way it was a delight to see.
As a result, when I began thinking about today’s post my mind kept returning to eagles so I thought I’d present several images taken at Farmington two winters ago.
I’ve said before that one of the skills that can be of immense value to the bird photographer (and of interest to birders of every persuasion) is the ability to predict the behavior of your subject and one of those behaviors that can be of most value to predict is take-off.
Some of you may recall that last November I photographed an amazing encounter between a Prairie Falcon and a hapless Northern Shoveler along the causeway to Antelope Island. These are photos of that experience that I haven’t posted before.
This past May while photographing a pair of nesting Osprey at Flaming Gorge I observed a behavior that was new to me. It’s a little thing but when added up these little things all help to fill in the big picture – a better understanding of the species.
Northern Harriers are well-known for aggressive behavior toward larger raptors intruding on their territory but seldom chase off raptor species smaller than themselves. This interesting behavioral quirk apparently results from the ability of harriers to steal food from smaller raptors. It’s easier to pilfer prey from a smaller species than it is to catch it yourself so harriers let them hang around.
While photographing a juvenile male Mountain Bluebird in Montana last week I was struck by the interesting variation in color and patterns of the adult male in breeding plumage as compared to those of the juvenile male. I thought some viewers might be interested in a photographic comparison of some of their development stages.
A little over a month ago I found this juvenile Red-tailed Hawk just standing around on a gravel road in the Centennial Valley of Montana. It’s behavior seemed at least a little odd because I’d never seen this species act so nonchalant when perched so low for so long – especially on a road.
In my experience American Avocets have two primary “styles” of stretching. When they stretch a single wing they extend it to the side with one leg stretched out behind. But they also use what’s called the “two wing stretch” and this style is often a precursor of imminent behavior – takeoff.
