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. …
Lark Sparrow
I’ve never had much luck with Lark Sparrows but this spring my fortunes with them have improved. It seems to be a banner year for them on Antelope Island and some of them even cooperate occasionally. In fact, most of the images in this post are of the same bird. It was so intent on its singing and territory declaration that it flew from perch to perch for quite a while and gave us some close looks. 1/1600, f/10, ISO 500, 500 f/4, 1.4 tc These are large, long-tailed sparrows with a distinctive chestnut, black and white facial pattern that gives them a harlequin look. The sparrow is perched on a dried sunflower with significant depth so I went to f/10 for this shot to try to get as many of the seed heads as sharp as possible. 1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc In this shot the same sparrow is changing its position on a sagebrush perch and I was able to catch it with a wing and tail position that I like. I do wish there were no sage leaves behind the head though. 1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc After it settled its position on the sage it gave me some nice eye contact. 1/3200, f/8, ISO 500, 500 f/4, 1.4 tc I’ve said before on this blog how much I enjoy sage perches but they’re not without their problems for the photographer. Dead twigs from last years growth often stick up above the…
The Mystery Of The Curlew Egg
A couple of days ago we spotted a far off Long-billed Curlew in flight with something in its bill. It was much too distant for decent photos but I was curious about what it was carrying so I scoped it with my 500mm. Even at that great distance it was obvious that the bird was carrying an egg. I actually fired off a couple of frames but the curlew was so far away that I just deleted those images when I got home. I wish I hadn’t now… I’ve seen and photographed birds carrying egg fragments from the nest after the hatching of their chicks multiple times but this seemed a little strange because it looked like an entire egg rather than just a fragment (which I didn’t think at all likely or even possible). Another thing that strikes me as unusual is the fact that this bird was several hundred feet in the air and flew a significant distance with the egg even though BNA Online says that when curlews dispose of eggshells they fly only “several meters” from the nest before alighting to drop the shell. We watched the bird fly and then eventually land on a gravel road where we were able to find the abandoned egg. Here you see it undisturbed as we found it. Now I’m no curlew expert but I’m going to speculate that this egg didn’t “hatch”. It doesn’t look like it has been pipped from the inside by the egg tooth of the chick and besides the hole in the egg simply has to…
