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.
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.
In Montana (and elsewhere I presume) orange paint on fence posts is used to mark private property and prevent trespass and hunting without permission on private lands. Apparently some land owners are color blind and use red paint instead of orange but the universally understood message is still the same – stay out!
Not all of the posts are so-marked (perhaps 10%?) but the birds I photograph sure have a nasty habit of choosing those ugly posts to perch on when I’m trying to photograph them. Such was the case with this Swainson’s Hawk a few days ago in western Montana.
On the evening of our last full day in Montana we spotted a couple of Swainson’s Hawks engaging in a playful dogfight down the road in front of us. As we got closer they hopscotched from post to post but allowed me to get fairly close for a few minutes.
Mia and I often joke with each other that we’d make terrible landscape photographers because we’d be bored by all the waiting around for ideal conditions such as dramatic clouds and perfect light. We much prefer the excitement, unpredictability and the occasional and unexpected delights of bird photography. This Swainson’s Hawk was one of those nice surprises.
This bird was one of the early migrants into Utah in the first week of April this year. Swainson’s Hawks winter in South America, which means they funnel through narrow Central America as they migrate each way. To give you an idea of how many birds that involves, 845,000 of them have been counted as they passed over Veracruz, Mexico in a single autumn. Incredible! 1/2500, f/6.3, ISO 500, 500 f/4, natural light, not baited, set up or called in I found this bird in a remote area of Box Elder County, hunting from power poles. One of the reasons I like this image is because it’s fairly unusual for me to get a raptor in full flight (instead of just after taking off, note the position of the feet) when it’s not soaring or gliding with its wings in a horizontal position. I’m always interested when I can get images that contrast the ventral and dorsal colors and plumage patterns of the same species in flight. Swainson’s Hawks are quite dark dorsally. 1/2500, f/6.3, ISO 500, 500 f/4, natural light, not baited, set up or called in But when you can get good light in the ventral view, the contrast is striking. Even though these two images were taken 34 minutes apart, I’m relatively certain that it’s the same bird in both shots. This hawk was coming to land on a power pole and even though the flight position screams for a perch in front of the bird, I took the liberty of cloning out the ugly pole…
It goes without saying that light angle, intensity and warmth can have huge effects on an image, both positive and negative. I thought it might be interesting to see the effects of different types of light on the same species – in this case, Swainson’s Hawks. 1/160, f/6.3, ISO 640, 500 f/4, 1.4 tc, natural light, not baited, set up or called in Here, the sun was low and the light warm. The light was directional (side lighting the bird) but it worked pretty well because the darker parts of the bird are in the direct light. The head angle is just right for this pose – if the head were angled any more toward me I’d have lost the catch light and light on the face. If it were turned any more away from me I’d have lost good eye contact. 1/1250, f/5.6, ISO 640, 500 f/4, 1.4 tc, natural light, not baited, set up or called in Like in the previous image, this hawk is side lit. The difference is that the bird has its light, creamy colored belly facing the sun so the whites, though they’re not blown out, are a tad too bright and lacking detail. 1/2000, f/6.3, ISO 500, 500 f/4, natural light, not baited, set up or called in I took this image a little later in the morning, so the light wasn’t so warm and at that angle enough of it is reflecting up from the ground to give me sufficient detail in the shaded, dark brown plumage…
On my trip to Montana’s Centennial Valley last month Swainson’s Hawks were very abundant. I found two families of them that would reliably hunt close to a road and since they had become habituated to the traffic they were easier for me to approach as long as I stayed in my pickup truck. 1/1000, f/7.1, ISO 500, 500 f/4, 1.4 tc This was one of two juveniles along the river at the west end of the valley. Both birds, along with their parents, would repeatedly perch on posts and poles close to my pickup. But it was very difficult to get an acceptable light angle at this location in the morning so I include only this one shot of those birds. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc I had more luck with another family (two juvies and one parent) at the east end of the valley. The light angle was better and I also preferred the fence posts in this area – they were older and had more character. 1/500, f/11, ISO 500, 100-400 @ 400mm Occasionally I was able to get both juveniles in the same shot but of course that situation often brings with it a depth of field problem so I switched to the 100-400 zoom and set my aperture at f/11 and focused on the post between the two birds. It seemed to work pretty well. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc I loved the “butterscotch” colors on these two juveniles – particularly this one. 1/2000,…
Western Montana has been awash in Swainson’s Hawks this summer. From the Canadian border (Glacier County) to the southern border with Idaho (Beaverhead County) I found them in significantly larger numbers than I have seen in previous summers. I hope this very unscientific observation is accurate and that it bodes them well as a species because their numbers have been declining to the point where they are listed as a Species of Special Concern in several western states. 1/2000, f/7.1, ISO 500, 500 f/4 I found this handsome juvenile this past week along a county road in Beaverhead County. At first it was very relaxed and assumed this clenched fist pose that is so typical of many buteo species when they’re at ease and resting. 1/1600, f/7.1, ISO 500, 500 f/4 But soon it began to arch its neck and I recognized that it was about to attempt to expel a pellet. I had already taken my tc off in anticipation of take-off so I decided to leave it off because so often in the past I’ve missed the falling pellet as it dropped out of frame at the bottom. 1/2000, f/7.1, ISO 500, 500 f/4 Then, with the nictitating membrane pulled over the eye, the bird began to retch. These few images showing pellet ejection may give the viewer the impression that it all happened very quickly. It didn’t. From beginning to end the whole process took over four minutes. During that time there were alternating periods of retching and resting and it didn’t look to be a…
A couple of weeks ago I watched as a couple of juvenile Swainson’s Hawks hunted grasshoppers on the ground in Montana’s Centennial Valley. The birds were often largely obscured by grasses so I waited for take-off. . 1/2000, f 7.1, ISO 500, 500 f/4, 1.4 tc In a situation like this it’s usually very difficult to lock and maintain focus on the bird as it takes off because of the closeness of the grasses in the background – typically autofocus tries to lock on to the background elements when they’re this close to the subject. But in this case there was enough contrast between the light-colored grasses and the relatively dark bird that I was able to get 13 images where the bird was sharp and no body parts were clipped. The problem with many of them (as often happens) was that the timing of the wing flaps was synchronized with the burst rate of my Canon 7D and the wing position in many of those shots wasn’t ideal. I wasn’t bothered by the flying insect below the bird for two reasons: 1), it amused me because it almost looks like the bug is taking flying lessons from the hawk and 2), it was natural and it was there. 1/2000, f 7.1, ISO 500, 500 f/4, 1.4 tc When I get similar shots such as these I can’t help comparing the strengths and weaknesses of each. I prefer the better eye contact in the first image but like the wing and tail position and better light under the wing…
This morning we headed north once again in quest of Golden Eagles. We found a few but they were too far away for decent photographs. The consolation prize was this cooperative Swainson’s Hawk – our first of the season which delighted us. In fact there were two of them, hanging out in the same general area. 1/1600, f/6.3, ISO 500, 500 f/4 This bird was particularly fond of a couple of telephone poles in northern Box Elder County. Here it is returning to the pole after leaving it for a short and unsuccessful hunting foray. I’m not particularly happy with the wire and insulator but I liked the landing pose. 1/2000, f/6.3, ISO 500, 500 f/4 Sometimes this hawk perched on the top of the pole but one time it landed on the second wire strung below the first one. Here it is taking off from that position with the pole directly out of frame to the left. I like the dynamics of the take-off in contrast to the greater concentration demanded during landing. 1/2500, f/6.3, ISO 500, 500 f/4 I got a few shots of the hawk in full flight with legs tucked away cleanly. 1/2000, f/6.3, ISO 500, 500 f/4 Another take-off and for this one I had to clone out a small bit of the wire at lower left. Cloning is something I don’t like to do but I do succumb to the temptation occasionally in certain situations. A judgement call… 1/2500, f/6.3, ISO 500, 500 f/4 I was…
A recent comment on this blog by Mike Shaw reminded me that I’ve never made a Swainson’s Hawk blog post. Part of the reason is because I’ve had relatively few opportunities with them so my files are limited. But in reviewing my images I thought I had enough acceptable photos to make a representative post on the species. I’ve deliberately chosen shots that show these hawks from a variety of angles – front, back, side and in flight. 1/2000, f/7.1, ISO 400, 500 f/4, 1.4 tc I found this young bird hunting grasshoppers along a gravel road at Red Rock Lakes National Wildlife Refuge. It would catch a ‘hopper, eat it on the road and then return to a nearby fencepost to watch for more of them. The bird seemed to be fearless and paid me very little attention. 1/1200, f/8, ISO 400, 500 f/4 Occasionally it would land on a different post but it didn’t stray far for quite a while. With this pose we get a good look at the back side. 1/1600, f/8, ISO 320, 500 f/4 I thought this screaming pose was interesting enough to include here despite the nictitating membrane partially covering the eye and the slight tightness on the tail. 1/1000, f/8, ISO 320, 500 f/4 This is a different bird and I include the image for the good look at the underside plumage patterns in flight. 1/1600, f/8, ISO 500, 500 f/4, 1.4 tc I found this cooperative adult at Farmington Bay Wildlife…
