Western Grebes Dumping Their Chicks
I haven’t posted for a few days because I’ve been in Montana for most of the past week. I have many images from that trip and hopefully some of them will appear here in the near future. But for now I’d like to report on another grebe behavior I photographed recently. This time it will be the Western Grebe, rather than the Clark’s Grebes in two of my recent posts. The two species are very similar and most easily distinguished by differences in bill color (Clark’s is bright yellow to orange-yellow while the Western’s bill is yellow to dull olive colored) and coloration around the eye (Clark’s is white surrounding the eye while the Western is dark around the eye). Both species rarely fly except during migration. In fact for much of the year they are incapable of flight because their flight muscles atrophy soon after arriving at their breeding grounds. So it’s my working theory that this might explain part of the reason why these grebes do so much wing flapping and stretching while sitting on the surface of the water – to excercise their relatively unused wings. Note: In many of these images I was too close to the birds to get an aesthetically pleasing composition so in most cases the birds will be too tight in the frame. But I think they show well the behavior I’m describing. 1/2000, f/10, ISO 500, 500 f/4, 1.4 tc This Western Grebe is in the middle of a wing-flap. They look so lithe and streamlined while…
Short-eared Owls In Flight
These three images are of a mated pair of Short-eared Owls taken two years ago at Red Rock Lakes National Wildlife Refuge in southwest Montana. 1/1250, f/5.6, ISO 800, 500 f/4, 1.4 tc This is the male delivering a vole to his family. As you can see from my techs I had to max out my settings (especially on the last two images) to try to get enough shutter speed for flight shots. Each of these photos was taken on different mornings but the light was consistently a challenge while we were there. 1/800, f/5.6, ISO 800, 500 f/4, 1.4 tc This is the elusive female. I got very few shots of her because she spent most of the time on the nest with her two chicks and I rarely saw her fly. 1/800, f/5.6, ISO 800, 500 f/4, 1.4 tc Another look at the male. There’s a good reason for the timing of this post – we’re at Red Rock right now (I prepared this post before leaving and post-dated publication) and anticipation of this trip had me thinking about these wonderful owls again. We’d have to be pretty lucky to find cooperative owls again but if not there should be plenty of other birds to work with. The biggest challenge on this trip is likely to be light. Red Rocks is right on the continental divide and early summer weather up there is volatile and often down-right scary – especially when you’re pulling a camping trailer over 30 miles of dirt roads! These trips are…
Clark’s Grebe Chicks Competing For Food
One of the Clark’s Grebe behaviors I was able to photograph last week was the adults feeding their chicks. The youngsters would be on the back of one parent while the other one brought in fish for breakfast. They were always small fish, to accommodate the very young chicks. Some of these aren’t great photos but collectively I think they tell an interesting story. I had been shooting faster action just prior to this sequence so my settings for the first shot aren’t particularly appropriate but then I quickly adjusted. 1/4000, f/6.3, ISO 640, 500 f/4, 1.4 tc The parent bringing in the fish wouldn’t give them directly to the chicks but instead would hand them off to its mate and then that bird would feed the youngsters on its back. Here the parent on the left has just given this small fish to the brooding adult. 1/2500, f/8, ISO 640, 500 f/4, 1.4 tc The chick in the water knew it had no chance to get the fish while it was there so it immediately made a bee-line for the back of its parent. When they’re this size they still struggle to get on board. Sometimes the parent sticks a leg out backward for the chick to climb up on but this youngster was on its own and was frantic to get up front where the food would be doled out. 1/2500, f/8, ISO 640, 500 f/4, 1.4 tc I imagine it’s not easy getting up there since they have to work against the grain of the feathers of the…
Male Northern Harrier In Warm Light
Just a single image this time. I found this male Northern Harrier trying to catch some warming rays soon after the sun came up on a cold morning this past winter. 1/1250, f/6.3, ISO 640, 500 f/4, 1.4 tc I was too close to keep from clipping body parts as he lifted off but as you can see I was fighting for depth of field and shutter speed in this light anyway so I was reasonably happy to get what I did.. One of the few things I miss about frigid winters is the approachability of some of the raptors when it’s very cold. I could never get this close to a perched harrier in the summer months. Ron
Can’t We Go Any Faster Dad?
I’ll preface this post with an apology for the cutesy title. I usually avoid them at all costs but in this case I just couldn’t help myself… (I’m making the assumption that the adult bird here is the male because of its straight bill but it’s a subtle distinction and I could be wrong). For the last few days we’ve been having a great time with Clark’s and Western Grebes and their chicks. Both sexes of both species brood their chicks on their backs (back brooding) from almost the moment they hatch until they are quite large. I’ve seen up to three chicks of about this size on the back of a single adult, although by the time they get this size the other parent often shares the burden. 1/1600, f/8, ISO 400, 500 f/4, 1.4 tc When I first saw this image of a Clark’s Grebe and its chick on my screen I assumed it was simply another case of the youngster having just jumped onto the back of the adult (as evidenced by the position of the feet and the direction of the water splash). But now I’m quite convinced that the adult was actually allowing the youngster to act as an outboard motor of sorts as the chick seems to be providing the propulsion as the parent relaxes. If so, and I think it is, in all the time I’ve spent watching these birds this is the first time I’ve noticed such interesting behavior. I offer this image as further evidence of my theory…
“Rushing” Western Grebes
The ritualized displays and courtship ceremonies of Western Grebes are among the most complex known in the bird world. One of them is called the “rushing ceremony” which includes 5 distinct phases – only one of which is actually referred to as “rushing”. Yesterday I finally was able to photograph this most dramatic part of the display and believe me it’s been a long time coming. Mia and I were photographing a pair of these grebes with chicks and though we both were aware of another small group of grebes a little further away I was concentrating so intently on those chicks that I didn’t notice what Mia noticed – that the behavior of two of those birds had suddenly changed. She said “they’re going to do something” so all I had time to do was quickly aim my lens at these birds and fire away. Without Mia I’d have missed the entire sequence. 1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc When rushing, the two birds (usually a mated pair but two males may also do it to attract females) lunge forward and rise completely out of the water. 1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc As their legs and feet start to churn at incredible speeds their bodies begin to become more vertical… 1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc until the birds are almost completely vertical to the water and their feet are slapping the surface so fast (16-20 steps per second) that the slapping and splashing noise is loud and can be heard a great distance away. The…
Fledgling Loggerhead Shrike Learning The Ropes
Yesterday we came across this Loggerhead Shrike fledgling perched high and pretty in the early morning light. 1/500, f/8, ISO 640, 500 f/4, 1.4 tc A few minutes after this shot was taken the bird flew off so we decided to look for more opportunities elsewhere and left the area. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc Just before we quit shooting for the day we decided to look for the fledgling again in the same area as before. We found two of them this time – one flew off almost immediately but this one allowed us some close observations for about 25 minutes. By this time of the morning the bird was side-lit in most situations but we got to see some interesting behaviors. Typical of youngsters this one was curious about its surroundings and spent quite a bit of time exploring the greasewood bush it was in. Here it is about to half hop/half fly to the twigs in the upper left of the frame. 1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc Several times it picked off one of the drier greasewood buds and played with it for a while. 1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc But a parent coming in with food always got the full attention of the fledgling. In this image one of the adults is delivering a grasshopper to the begging young bird – you can just see the top of the parents head at the bottom of the frame as it works its way…
Rough-legged Hawk on Tamarisk
I’ve said before that for me the Rough-legged Hawk is among the most handsome of North American raptors. 1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc I found this bird perched on some tamarisk just below an elevated road on Antelope Island and was able to get some shots I like as it lifted off. I’ve posted another image of the sequence here. In late April of this year state park personnel cut down the stand of tamarisk. I fully understand the need to get rid of them because tamarisk is an invasive plant that is widely believed to degrade native wildlife habitat and disrupt the structure and stability of North American native plant communities. That said I will miss them as there aren’t many elevated and attractive natural perches on the island. Ron
Eared Grebes In Utah
Eared Grebes are the most abundant grebe on the planet and immediately after the breeding season most of the population on this continent migrates to either Mono Lake, California or the Great Salt Lake in my back yard where they feed on brine shrimp and brine flies. 1/800, f/7.1, ISO 500, 500 f/4, 1.4 tc Most of the grebes that I see are on the Great Salt Lake where it’s difficult to get quite close enough to them for photography purposes but occasionally I’ve seen them on smaller ponds where they’re attracted by insect hatches. 1/400, f/8, ISO 500, 500 f/4, 1.4 tc The eye of this species is incredibly red, almost unbelievably so. Just to be clear, I’ve not applied any saturation to these photos. 1/800, f/7.1, ISO 500, 500 f/4, 1.4 tc These birds are tireless feeders and divers. In scientific studies it’s estimated that they consume between 8,000 and 70,000 brine shrimp per day. That’s a lot of diving! 1/1600, f/8, ISO 500, 400 f/4, 1.4 tc When there’s an insect hatch they feed on the surface and as they scurry from bug to bug they’re very difficult to follow because of their quick turns and amazing swimming speed – it can be almost as challenging for the photographer as photographing small birds in flight. Here the grebe has spotted a floating midge on the left… 1/1600, f/8, ISO 400, 500 f/4, 1.4 tc approaches the midge very quickly… 1/1600, f/8, ISO 400, 500 f/4, 1.4…
Clumsy Prairie Falcon
This young Prairie Falcon had apparently been hunting ducks near the edge of the Great Salt Lake and got some of its belly feathers wet so it landed on a rock near the lake for some rest and preening. It posed for me for over 12 minutes which I appreciated but the light was low and variable due to the ever-changing thickness of the clouds. 1/800, f/6.3, ISO 500, 500 f/4, 1.4 tc At first the falcon was fairly wary of me because I was quite close. 1/800, f/6.3, ISO 500, 500 f/4, 1.4 tc But after a few minutes it settled into its preening again. 1/2000, f/5.6, ISO 640, 500 f/4 But this was a juvenile bird and not quite so suave and sure of its movements as an adult would be and suddenly it slipped on its perch and would have fallen backwards if it hadn’t caught itself with its wings and climbed back up on the rock. Even though I didn’t get much light in the eye I still got lucky on this shot. I’d been shooting this bird with my tc attached and at a relatively slow shutter speed and the falcon pretty much filled the frame. Just before I took this image I removed my tc and ratcheted up my ISO to get more shutter speed for a possible take-off shot. If I hadn’t done that the wings would likely have been soft from motion blur and I’d have cut off parts of the bird with the tc attached. …
