It’s only January 1 and I’m already becoming weary of snow, cold, bleak landscapes and the dirty air of winter inversions. So I choose to welcome the New Year with a touch of Spring – Ferruginous Hawk chicks on the nest.
Two days ago I posted about a very tame juvenile male Prairie Falcon I photographed last week in the Centennial Valley of Montana. The bird had two bands and I was extremely curious about where, when and why the falcon was banded and by whom so I asked for any insight my readers might have about the bands. Several of you jumped in with advice and suggestions, for which I’m much appreciative. But it was the superb sleuthing of my friend Mike Shaw that paid huge dividends. Mike did some research and learned that the colored band on the falcon (left foot) was issued to Doug Bell, Wildlife Program Manager for East Bay Regional Park District out of Oakland, California. On Tuesday, figuring that Doug might be interested in knowing that his California bird was now in the wilds of Montana, I emailed him with a link to that blog post and an offer to supply any more information about my encounter with that bird that he’d be interested in. I also asked him if he might tell me a little about his experience with the falcon. Yesterday Doug responded generously with information and photos. Since many of my readers expressed an interest in knowing about the history of this young bird I decided to update you with a new post rather than add an addendum to the previous post that many might not see. Besides, there’s a lot of new “stuff” here. Image property of East Bay Regional Park District – used by permission Doug and his team banded “my” Prairie Falcon…
Long-billed Curlews spend most of the late spring and early summer at mid-elevations on Antelope Island while nesting and raising their chicks but by this time of year they begin to bring the youngsters down to the shoreline. That’s where I photographed this lone adult with a single youngster yesterday morning.
Well, yesterday may have been the first day of spring but so far I’m not impressed – it’s been dreary and wet and it’s supposed to be very cold through the weekend. I’ll even have to turn the heat on in my de-winterized camping trailer to keep the plumbing from freezing, Ugh… So I’ve been stuck in the house and was going through some older images when I came across this series of a very young Killdeer chick at Farmington Bay WMA. It was in the grasses near a parking lot and it was just as curious about me and my pickup as I was about it. 1/800, f/8, ISO 400, 500 f/4, 1.4 tc, natural light, not set up or called in I’d taken a few shots of this chick just after the sun came up but it was so buried in the grasses that the images weren’t very good but when I came back to the parking lot 51 minutes later it was in an area where the grasses weren’t quite as thick. At first it just watched me and didn’t do much. One of the parents was nearby but neither bird seemed nervous about my presence in my vehicle. 1/500, f/11, ISO 400, 500 f/4, 1.4 tc, natural light, not set up or called in And soon it walked closer to me to check me out. 1/500, f/11, ISO 400, 500 f/4, 1.4 tc, natural light, not set up or called in Then it decided to do some posing for…
I was photographing adult male blackbirds when suddenly this very recently fledged youngster popped up in the cattails right in front of me. At first I thought it was just curious about me and my big truck but that turned out not to be the case.
Temperatures are finally warming a bit here in northern Utah but the world is outside is still monotonously white. Yesterday morning I measured 22 1/2″ of snow on the north end of Antelope Island, indicating that our bleak and largely featureless landscape will remain the same for the foreseeable future. So this morning I needed a break and decided to post an image (taken this past June at Bear River MBR) that would remind me that spring is somewhere out there on the distant horizon. 1/3200, f/7.1, ISO 640, 500 f/4, 1.4 tc, natural light Western Grebes are devoted parents to their incessantly hungry and noisy chicks. The male and female take turns with their parental duties – one will back brood the youngsters while the other delivers fish and then they alternate responsibilities. Here the female (smaller than the male, with a shorter, thinner bill – thus sexual dimorphism) has caught a small fish and is delivering it to the male. Usually the parent receiving the fish will give it to the chick, as happened here. As I’m sure is obvious, I’m very much looking forward to watching and photographing springtime bird activities once again. It’s going to be a very long 2-3 months… Ron
I try not to play favorites when it comes to bird subjects for my photography but Short-eared Owls would have to be near the top of any such list I might make. I’ve had some luck with them here in Utah but my favorite area to photograph them is in southwest Montana. This series is from the summer of 2010 in Beaverhead County. I spent several days watching and photographing a male owl hunt voles and then bring them in for his family (female and two chicks) at the nest at the base of a sagebrush. I thought it might be interesting for some to see a full series of shots (of those I kept) as the male approached the nest with a vole. 1/1600, f/6.3, ISO 800, 500 f/4, 1.4 tc, shot from pickup window, natural light Like me, this male was a creature of habit. I would watch him hunting far off in the distance and when he was successful he would always repeat the same pattern. He would bring the vole in to the vicinity of the nest and then land on one of two favorite perches for a short time before delivering the vole to his family. This small sagebrush was one of those favorite perches – the other was a metal post. Here, he is in the process of landing and you can see the dark vole in his left foot. He always carried the vole to the perch in his left foot (as I’ve documented here) and always transferred…
Anyone who has spent a significant amount of time observing Western Grebes (or their close relatives, Clark’s Grebes) has undoubtedly observed this curious behavior multiple times. But before I continue, a few words of explanation are in order. Grebes are unique to most other water birds in two ways that are related to this behavior: 1.) their legs are attached to their bodies at the rear, rather than underneath and 2.) the toes of grebes are lobed instead of webbed. Having legs attached at the rear allows for efficient swimming but causes extreme clumsiness while walking – they rarely venture on to land, but when they do they often fall down after just a few steps. This leg attachment position is so distinctive of grebes that the genus name of four of the North American grebe species is Podiceps (from “podicis” meaning anus or vent and “pes” meaning foot) – in other words, “anus foot”. (and yes, I’m having a hard time resisting a joke line or two with that phrase…) Recent experimental work with grebes has demonstrated that the lobes on the toes function much like the hydrofoil blades of a propeller. Ok, with that background, on to this strange behavioral quirk of the Western Grebe. Without warning, and for no apparent reason, they stick one of their legs out behind them. With those unusual feet it can look pretty silly. Sometimes they’ll do a simultaneous wing stretch, but rarely. Occasionally they’ll hold the foot high in the air for quite a while. That can look even sillier. Even the chicks do it….
Like every other bird photographer many of the photos I take are not worth keeping. For the first few years I was shooting birds I estimated that I deleted 90% of my images. Now that I’ve become a little more discriminating that number is probably closer to 95%. Birds are incredibly difficult subjects – they’re fast, unpredictable, difficult to approach and generally uncooperative. When I’m culling images after a day in the field most shots fall under two main categories – keepers and garbage. But there’s often a few that are technically lacking for one reason or another but have some unusual or especially interesting feature that makes it difficult for me to trash them. So I don’t. Occasionally I go back through them just for the fun of it. I enjoy them and thought some of you might too so here’s a few from the past month or so. 1/2500, f/7.1, ISO 500 500 f/4, 1.4 tc This one’s from yesterday – a Lark Sparrow that posed and groomed for us for quite a while. Looking through the viewfinder I had no idea there was a second Lark Sparrow in the vicinity and didn’t even notice it flying through the frame until I got home and looked at it on my computer. Mia said that she’d noticed the second bird and that it chased the first bird away when it flew. Anyway, I thought the out-of-focus sparrow to the left was an interesting serendipity. I just wish the two twigs by the head weren’t there. 1/2500, f/7.1, ISO 500 500 f/4, 1.4…
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…
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,…
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…
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…
In previous posts (here, here and here) about these Short-eared Owls at Red Rock Lakes National Wildlife Refuge I’ve shown and described snippets of the fascinating behaviors I observed when this male would deliver voles to the female and two youngsters at the nest. But it struck me that I’ve never put the whole process together in sequence so the behaviors could be fully appreciated so that’s what I’ll attempt to do here. Most of the images will be different from those in the previous posts. 1/1250, f/5.6, ISO 800, 500 f/4, 1.4 tc The male was a tireless and highly skilled hunter and I never saw him with any prey other than voles. When successful he would always return to the vicinity of the nest and land momentarily on one of two favorite perches – the dark sagebrush at lower right in the above photo or a metal post a few feet from the sagebrush. Here he’s coming in for a landing on the sagebrush with vole in talons and glances up at me to make sure all is safe. I really like the intense direct eye contact in the shot. 1/1000, f/5.6, ISO 800, 500 f/4, 1.4 tc Now he’s focused on the sagebrush in order to make a successful landing. 1/1250, f/5.6, ISO 800, 500 f/4, 1.4 tc This time he stayed perched for less than five seconds and didn’t even pull his wings in against his body – he just kept them out or up while he seemed to contemplate his next…
I’ve been fascinated by the mating displays of American Avocets ever since I first started photographing them almost five years ago. This innate and complex choreography is almost identical in different mated pairs and from year to year. The action happens quickly and is difficult to photograph well but I think I have enough decent images now to make an informative post about it. Not all of the photos are of the highest quality but I think each of them illustrates the behavior well. I’ll present several sequences of different birds that will illustrate most of the important stages of the process. I’m not going to include my techs with these shots -some of them were taken when I first started photographing birds and I made many mistakes in my setting choices. Knowing some of these settings wouldn’t help anyone. Avocets are monogamous and pairs form up in the spring when the female persistently associates with the male until she is eventually tolerated, then accepted as a mate. The female initiates copulation by the posture you see above. It’s called Solicitation Posture and in it she holds her neck extended far out and low. At times it’s so low that much of the head, bill and neck are under water as you’ll see in a later image. Once interested, the male performs Sexual Preening where he stands close to the female and extends his neck so that his bill tip can preen his breast (always on the side closest to her). You’ll see that part of Sexual Preening in a later image but…
