Northern Harrier Flight Sequence

Eight days ago I photographed a Northern Harrier as it flew toward me at an angle and then banked away. The following day, because of time constraints and computer issues I posted only a single shot of the banking maneuver but now I wish I had posted the entire flight sequence of four images. With your indulgence for posting the same image twice I’ll do just that this morning.

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.

Male Northern Harrier Hunting

The Northern Harrier is arguably my favorite subject and I tend to post images of them often. Their dramatic sexual dimorphism in plumage color almost makes it seem as if I’m photographing two different species when I compare adult males to females.

Eye Defects In Raptors

Over the years I’ve seen a number of birds with eye problems. Some of them appeared to be infections and others injuries but I’m beginning to notice a pattern of symptoms that looks similar from bird to bird – particularly in raptors. I’ve included two examples here.

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”.

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.

Anticipating Raptor Take-off

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.
