Western Grebe Chick – A Lesson Learned In Feather Eating

Most grebe species are well known for feather-eating and the Western Grebe is certainly no exception. I’ve seen and photographed them gobbling down feathers multiple times. While the purpose of such behavior remains unproven it is suspected that the feathers enable more efficient digestion of fish bones and aid in removing digestive parasites. I’ve discussed this in further detail and provided more images of the behavior here. 1/2000, f/8, ISO 500, 500 f/4, 1.4 tc The feathers on their flanks and scapulars are in almost constant molt and when grooming dislodges them they are deliberately swallowed. Often, as was the case here, the feather is floating on the surface of the water and the grebe simply snatches it up as it floats by. 1/2000, f/8, ISO 500, 500 f/4, 1.4 tc But this time the feather was fed to the chick on the back of the parent. Adults begin feeding feathers to their offspring on the first day of their lives. BNA reports that researchers have found over 300 feathers in the stomachs of individual chicks that were no more than three days old. 1/1600, f/7.1, ISO 500, 500 f/4, 1.4 tc But of course not just any old feather will do. It must be small, soft and downy and without a stiff quill but apparently this is a lesson that the chicks must learn for themselves. As soon as the youngsters begin to make occasional forays off the backs of their parents and into open water they begin to experiment with feathers they…

Western Grebes – Aggressive Speed Demons

I’ve spent a lot of time over the years watching and photographing the behaviors of Western Grebes and I’ve been impressed by both their aggressive tendencies toward other birds and by their incredible acceleration and speed in “running” across the water at those same birds. In my experience that aggression is most often directed toward other grebes in defense of mates, chicks or feeding areas but they are also aggressive toward a variety of other species and are suspected of stabbing them with their bill from under water. BNA reports Mallards and Red-necked Grebes found dead from stab wounds to the abdomen that were probably administered by Western Grebes. I’ve found photographing them as they dash across the water to be very challenging because of their speed and the unpredictable nature of the behavior – it usually comes with little or no warning and direction is difficult to anticipate. 1/1250, f/6.3, ISO 640, 500 f/4 Though these birds appear slim while sitting on the water, in reality they are fairly chunky and at the end of one of these “runs” their wide body throws up quite a wide wake as they begin to slow down and settle back into the water – much like a speedboat after the engine has been cut. 1/1000, f/6.3, ISO 500, 500 f/4, 1.4 tc This grebe is early in the acceleration stage with its “bow” still raised high. 1/1000, f/6.3, ISO 500, 500 f/4, 1.4 tc And then another wake as it begins to settle into the water. 1/1600, f/6.3, ISO 500,…

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…

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…

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…

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…

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…

Curlew Peekaboo Take-off

When Long-billed Curlews take off they have a little trick they use to get airborne quickly. This is our largest North American shorebird and in addition to their extremely long bill they have very long legs. Since this is a grassland species it would often be very difficult to get a running start at take-off through the tall vegetation so they use their long legs to full advantage by crouching so low that their belly often touches the ground and then they spring into the air by quickly straightening those very long legs (jumping). This can be problematic for the photographer wishing to get take-off shots because this is a large bird and they explode into the air so quickly that you tend to either cut off part of the bird or lose focus on the subject at the most critical point of the take-off. But knowing and anticipating their behavior can give you a better chance at a quality shot or two. These three images from yesterday on Antelope Island are sequential in a quick burst at take-off. The first two are of crappy quality but I include them to illustrate my point. Here the curlew has crouched as low as it can get prior to take-off. I temporarily lost sharp focus on the head because of the foreground vegetation and because of camera movement as I moved my aim upwards in an attempt to get the entire bird in the frame as it lifted off. In the second shot of the burst, focus has locked onto the bird again as…

Pied-billed Grebe With A Mouthful

Just a single shot this time. I’m often blown away by the ability of some species to swallow huge prey whole when I have trouble gulping down anything much larger than an aspirin without chewing it first. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc A few months ago I watched and photographed this Pied-billed Grebe for 13 minutes as it tried to get this fish down its gullet. Other grebes attempting to steal the prize didn’t make the process an easy one but eventually the bird was successful. It’s not readily apparent in this shot but the fish was much wider than the head of the grebe. I could hardly believe what I saw… Ron

An Osprey, A Fish And A Thieving Magpie

Yesterday Mia and I returned from a three day camping and photo trip to Flaming Gorge. We had great weather for most of our time there and as usual the scenery and ambience were awesome. At an elevation over 6000′ many of the birds that we usually see there apparently haven’t arrived yet but we spent some quality time with a pair of nesting Osprey – a species that I’ve had little luck with in the past. 1/2000, f/5.6, ISO 500, 500 f/4, 1.4 tc This pole with all the attached ugly hardware was within a few feet of the nesting platform and early one morning this Osprey landed on the pole with a freshly caught fish. At first I figured that this bird would deliver the fish to its mate on the nest (I have a lot to learn about this species) but it didn’t. It’s intention was to eat the fish itself but as you’ll see, those plans were delayed by an interloper. It didn’t take long for this Black-billed Magpie to show up and torment the rightful owner of the fish. This Osprey removed and dropped the intestines in pieces and it seemed obvious to me that the magpie had learned that particular feeding pattern and came looking for tidbits that had landed on the wires below the Osprey. Here you can see one of those bits in the beak of the magpie that it had picked off of the metal above its head. So far the Osprey doesn’t seem too…

Grebe Panic

These aren’t great images technically but I thought they documented a fascinating phenomenon well enough. Yesterday there were thousands of these grebes at the first bridge along the Antelope Island causeway. They were actively feeding at the current boundary where the water coming under the bridge met the still water in the north arm of the Great Salt Lake so they were bunched up in incredibly thick masses. Several species of gulls were also present. Each time a gull would pass over the grebes, those directly underneath the gulls would panic and dive into the very shallow water in front of the gull which would create quite the stir in the water. Those grebes just a few inches to either side didn’t react which created a dramatic visual phenomenon as the frothy splash moved in front of and directly beneath the gull. Those times the gulls flew along the length of the mass of grebes the “splash” would travel exactly the same speed as the gull for perhaps 75 yards. This was one of the few times when shooting birds that I wish I’d practiced more with the video capabilities of my Canon 7D. That would be a video that I’d like to see many times as it was quite the spectacle to watch. Ron

American Kestrel Eating A Vole (graphic)

A couple of months ago I came across this female American Kestrel along the causeway to Antelope Island. She had captured a vole and was in the process of eating it while perched on a road sign. The images I’ve presented here aren’t pretty and won’t appeal to everyone but as I’ve said many times before I’m fascinated by behaviors. 1//1600, f/6.3, ISO 500, 500 f/4, 1.4 tc She had already decapitated the vole and was in the process of disemboweling it when I found her. Kestrels routinely discard the intestines and she had previously removed the small intestine (portions of which can be seen near the underside of the tail). Here she is dropping the coiled mass of the large intestine. As she attempted to eat the vole the large intestine was right in front of her on the perch and she apparently found its presence right under her face as she dined to be offensive and distracting so she repeatedly tried to drop it over the edge of the sign to get rid of it. Three times she picked it up and dropped it but each time it landed on the edge of the wooden post without going over the edge. 1//1600, f/6.3, ISO 500, 500 f/4, 1.4 t Finally, on the third attempt, she succeeded in dropping it over the edge, but just barely. 1//2500, f/6.3, ISO 500, 500 f/4, 1.4 t Now with her dining table cleaned up she was able to attend to the rest of her meal. There…

Northern Harrier Defending Its Meal

Long ago I posted some images of Northern Harriers fighting over this Mallard but I have other shots of the fracas that I’ve never posted so I thought I’d share some of them today. 1/1250, f/8, ISO 400, 500 f/4, 1.4 tc For the moment this bird has sole control over the duck but it knows the situation to be tenuous at best. The wings-out pose and fierce look are fair warning to the other harriers in the vicinity (and there are lots of them) that any attempt to share in the feast will be met with resistance. 1/1250, f/8, ISO 400, 500 f/4, 1.4 tc These birds have been starving because of a brutally cold and snowy winter so this harrier begins a frenzy of feeding in an attempt to swallow as much food as possible before other birds move in. 1/1250, f/8, ISO 400, 500 f/4, 1.4 tc And it doesn’t take long before all hell breaks loose. At this point I often wasn’t getting enough depth of field for multiple birds so decided to risk f/10 and a slower shutter speed for the rest of the session. 1/800, f/10, ISO 400, 500 f/4, 1.4 tc I was lacking in both shutter speed and depth of field for this shot and I’m not happy with the shadow on the face but liked the talons on the back. 1/800, f/10, ISO 400, 500 f/4, 1.4 tc For a few moments both birds tolerated each other on the duck but that didn’t last long… …

Black-necked Stilt Stretching and Preening

The Black-necked Stilt is an elegant study in contrasts with its white breast and shiny black wings accentuated by extremely long, bright red legs. They’re often found feeding near American Avocets and I’ve routinely been able to get preening and stretching images of avocets but the stilts have been less cooperative with me. Typically they’ll actively feed when I’m near but they always seem to fly off to do their self-maintenance. 1/2000, f/6.3, ISO 400, 500 f/4, 1.4 tc However, this bird apparently decided that flying off was too much effort and it unexpectedly began a series of stretches. 1/2000, f/6.3, ISO 400, 500 f/4, 1.4 tc I was able to photograph a variety of interesting poses but by this time the sun was relatively high and so some of the best shots are missing light in the eye. Stilts often pull their leg up over the wing when scratching the head. 1/2500, f/6.3, ISO 400, 500 f/4, 1.4 tc Because these birds are usually wading in water when I’m photographing them the extreme length of their legs is not always evident but catch one in a pose like this and it becomes quite apparent. 1/3200, f/6.3, ISO 400, 500 f/4, 1.4 tc I like the water splash and pose in this shot. 1/2500, f/6.3, ISO 400, 500 f/4, 1.4 tc Here the stilt has finished stretching for the moment and is contemplating its next move… 1/2000, f/6.3, ISO 400, 500 f/4, 1.4 tc which turned…
