Grebe Running Across A Pond’s Surface To Protect Its Prized Fish

At first glance Pied-billed Grebes may come across as nondescript, bland little birds without much personality but I’ve found the opposite to often be true. When they’re not resting or grooming they’re active, quite vocal and when they’re feeding in groups they’re often aggressive, even pugnacious. Their kleptoparasitic tendencies can be entertaining to watch in the extreme.

Notice the layer of ice at the bottom of the frame – that ice will come into play later in the sequence.

Northern Harrier Showing Food Source Adaptability

Last winter Northern Harriers really struggled to survive here in northern Utah. For several months it was bitter cold with a thick layer of snow on the ground which made it close to impossible for our wintering raptors (including Barn Owls) to find and catch their typical prey – voles. So harriers were forced to look for other food sources, including small birds. Songbirds are relatively scarce here that time of year but this harrier got lucky.

The American Goldfinch

Due to ongoing copyright infringement issues I’ve recently spent enormous amounts of time registering many thousands of my images with the U.S. Copyright Office. During that process I ran across these American Goldfinch images that I’d essentially forgotten about. They were taken almost exactly 6 years ago (11/18/2007) when I was first learning bird photography.

Gadwall Stealing Food From A Coot

Gadwalls are well-known for stealing food (kleptoparasitism) from American Coots . They eat the same kinds of food (submerged aquatic vegetation), Gadwalls are almost a third bigger than coots and the two species often feed together in mixed flocks so being the bullies on the block, Gadwalls can’t resist taking advantage of the situation.

Black-crowned Night Heron Tongue

The Black-crowned Night Heron is the most widespread heron in the world. They are opportunistic feeders that feed on a wide variety of prey and I’ve seen them swallow some amazingly large prey items. I suspect that their rather interesting-looking tongue plays a significant role in their success.

Wilson’s Snipe Feeding Technique

A week ago today I had my best photo opportunity with the elusive Wilsons’s Snipe. Several of them, in fact. And this time they gave me an intimate look at their feeding behavior.

A Fly Turns The Tables On A Flycatcher

After yesterday’s depressing post I decided a little whimsy was in order for this morning.

Magpie With Nesting Material In Flight

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.

Wilson’s Snipe

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.

Ferruginous Hawk Nests

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 Harrier “Playing”

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”.

Short-eared Owls And The “Handedness Phenomenon”

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.

Fighting Harriers

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.

The Interdependence Of Short-eared Owls And Voles

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.

Bald Eagle Potpourri

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.
