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.
About a year ago I spent some time with this juvenile Red-tailed Hawk as it honed its hunting skills. It wasn’t yet a very good hunter but it sure tried hard. It typically perched on top of some rocky outcrops as it scanned the grassy slopes below for voles. Then it would swoop down and make its attempt, though it seldom caught anything that I was aware of. Learning to hunt isn’t easy and the price to pay for failure is a dear one.
Recently I’ve been reading some disturbing reports about the decline of the American Kestrel in North America. And I’m talking about a drastic decline! I’ve speculated about just that in a previous post, based on my own recent observations in northern Utah but I’ve been hoping that what I’ve noticed is only a local and temporary phenomenon. Apparently it isn’t.
This summer has apparently been a good breeding season for Ferruginous Hawks in southwest Montana. I photographed about a half-dozen active nests or recently fledged family groups in or near the Centennial Valley.
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.
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.
Two days ago I called Bill West, Project Leader at Red Rock Lakes National Wildlife Refuge in the Centennial Valley to ask him about the effects of the recent forest fires and resulting smoke in the area. During the conversation Bill told me about an incident that immediately got my attention.
Each time I look at this image, at first the wing above the head appears to be the birds right wing on the far side of the body. But then a few seconds later my brain tells me that’s impossible because the lower wing is obviously the right wing and it’s impossible (or at least highly unlikely) for the hawk to have two right wings.
Last week, partially in an effort to get away from the aggravations of the blog hosting problems I’d been having, I decided to make the extra long drive to extreme northern Utah in a quest for Swainson’s Hawks. We found quite a few and a delightful bonus was a plethora of Ferruginous Hawks in the same area.
No, the Roughies haven’t returned early from their northern adventures. It’s just that I got to thinking about them yesterday while looking through some older images and was reminded of how handsome they are and how much I look forward to their appearance in the fall.
This is the last in my four part series on the color morphs of the Swainson’s Hawk. Today the focus is on the dark morph.
This is the third of my series of four posts on color morphs of the Swainson’s Hawk that I photographed on my last trip to Montana late last month. Todays bird is an intermediate morph.
The three morph categories are convenient to use but color variation of Swainson’s Hawks is almost continuous from darker to lighter individuals so the morph categories are somewhat arbitrary. I sometimes struggle with feeling confident about which category a particular bird belongs in.
My last post was of a juvenile light morph Swainson’s Hawk transitioning into a subadult, this bird is an adult light morph and my next post will be of a dark morph Swainson’s (and perhaps an intermediate morph also) – this is turning into a series…
I’m always interested in the color phases of the various raptors I encounter so when we found this subadult Light Morph Swainson’s Hawk on July 25 on our last trip to southwest Montana it got my attention. These worn young birds look white-headed in spring and early summer because of fading – much different from the adults.
