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.
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 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”.
When Northern Harriers choose to hunt along the edges of the dirt roads I frequent they sometimes give me interesting looks as they pass by. This is one of them.
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.
I’ve been photographing Northern Harriers for years now and I still get a thrill whenever I can get close to one of these shy hawks. And if it’s an elusive adult male (the “Gray Ghost”), well that’s just icing on the cake.
When hunting, Northern Harriers have a distinctive buoyant flight. They glide with wings held in a strong dihedral and have low wing loading which allows them to fly low and slow as they search for prey. When watching them hunt there are times I think they’re going to fall right out of the air.
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.
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.
I have a strong affinity for Northern Harriers ( a little secret that’s difficult to conceal, given the vanity plates on my pickup). And though I love to photograph either sex there’s just something about the adult males that has a special appeal for me. Part of that attraction is probably the relative rarity of the adult male colors since the juvenile colors of both sexes resemble that of the female.
The males are called the “gray ghost” for good reason.
This hawk was attempting to gain altitude, thus the angled body with the wing raised high.
Baiting birds into close proximity for photographic purposes is a highly controversial subject, especially when it’s done to raptors. Often live bait such as store-bought mice are thrown in front of the photographer so that photos can be obtained of the bird in flight as it swoops down for the rodent.
Sometimes bird photographers have to be a little crafty to get the shot.
