The American Bittern may be the most elusive avian subject I’ve ever photographed. They’re solitary, cryptically colored and their preferred habitat is wetlands with tall, emergent vegetation. And they’re extremely secretive by nature. So much so that very little is known about their biology, which is too bad because perhaps if we understood them better we could more effectively manage their seriously declining populations.
I’ve spent a fair number of years now photographing Great Blue Herons and I’d never before seen this behavior from the species.
I intended this post to be a single image for my “Just A Shot That I Like” feature. It didn’t turn out that way. Six days ago I found this Great Blue Heron on the edge of a small, partially frozen creek with an almost vertical snow bank directly behind and very close to the bird. The heron was patient with me and I was close so I tried a variety of compositions using my 500 mm and 100-400 mm lenses. The incredibly fast shutter speeds were because of the bright snow and my forgetfulness in adjusting settings as I was juggling two cameras and lenses. In the end I couldn’t decide which composition I preferred so I’m presenting three of them here. 1/5000, f/6.3, ISO 500, 500 f/4, natural light This relatively tight vertical shows good detail on the bird and I like the close view of the swirly marks on the snow behind the heron made by a wing as it landed. 1/3200, f/7.1, ISO 500, 100 – 400 @ 400mm, natural light Some folks gravitate toward whole-bird reflections so I’m also including this composition. Ideally I’d prefer the bird to be slightly further left in the frame but cropping off the left makes the image too narrow vertically for my tastes and I have no more room on the right (image was taken vertically and is close to full frame). 1/6400, f/5.6, ISO 640, 100 – 400 @ 400mm, natural light A horizontal composition with the heron slightly smaller in the frame shows more of the…
Birds use a variety of tactics to deal with the harsh conditions presented by an unusually cold and snowy winter. Some are more effective than others. I thought it might be interesting to see a few of them that I’ve been able to photograph in the last several weeks. My usual disclaimer for posts relating to behaviors; many of these images are technically lacking but I think they do illustrate some of the conditions these birds are having to cope with. 1/2500, f/6.3, ISO 640, 500 f/4, 1.4 tc, natural light After a fresh snow, the food source for many small birds is largely hidden and unavailable without some extraordinary measures. This juvenile White-crowned Sparrow, and others in the flock, were flitting from one snow-covered perch to another in an obvious attempt at knocking the snow off so they could get to the seeds underneath. Here you can see the snow falling away and immediately afterward the sparrow fed on the uncovered seeds. 1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in When it gets very cold most water sources freeze up completely which makes fish largely inacessable to Bald Eagles so many of them turn to scavenging as their primary food source. But this species adapted very well to scavenging eons ago which is one of the reasons Ben Franklin looked in disfavor at the proposal to make the Bald Eagle our national bird. 1/1000, f/5.6, ISO 640, 500 f/4, 1.4 tc, natural light, not baited, set up or…
Black-crowned Night Herons are the most widespread heron in the world, breeding on all continents except Antarctica and Australia. They’re relatively common in northern Utah, although it’s somewhat unusual for me to see them around here during winter. 1/1600, f/8, ISO 500, 500 f/4, 1.4 tc, natural light So two days ago I was surprised to find this juvenile still lurking around the wetlands of the Great Salt Lake. We’re in the middle of an inversion which means it’s very cold (I was shooting in temps of -10 degrees F yesterday morning) so most still water is frozen solid. This bird was standing on ice with a thin layer of snow on top. 1/1600, f/8, ISO 500, 500 f/4, 1.4 tc, natural light Juveniles look very different from adults. Instead of the basic black, white and gray colors of the adults these young birds are brown-streaked ventrally… 1/1250, f/8, ISO 500, 500 f/4, 1.4 tc, natural light and mostly solid brown dorsally. This orange-chrome eye color will turn bright red in the adult. 1/1000, f/8, ISO 500, 500 f/4, 1.4 tc, natural light I didn’t realize it at first but this bird was in hunting mode. There’s a patch of open water just out of frame in front of the heron and the bird is watching it for fish activity. One time it made an incredibly fast move for a fish from this position but it missed. The heron didn’t stand any closer to the open water because the ice is…
Christmas Morning at Bear River Migratory Bird Refuge was nothing short of spectacular. We had great light, wonderfully clear blue skies and lots of birds. And it was cold – as low as 6 degrees F. Perfect! On this trip (which included the Promontory Point area) we saw a plethora of raptors – Bald and Golden Eagles, Red-tailed Hawks, Rough-legged Hawks, American Kestrels, Short-eared Owls, a Prairie Falcon and one Barn Owl hunting in daylight because of the cold. And I’ve never seen as many Great Blue Herons in one relatively small area as I did on that morning. Just before I stopped to take this photo there were over 100 of them on the ice of the canal to the right and along the far bank in less than 1/3 mile – which led to a topic of conversation. Mia is from Florida and we discussed how seeing Great Blue Herons on snow and ice seems incongruous to many folks from warmer climates. That conversation was the inspiration for this post. 1/4000, f/6.3, ISO 400, 500 f/4, natural light As is typical for western herons, these birds were difficult to approach (in some areas like Florida one can almost walk up and touch them at times). This juvenile was fishing in a patch of flowing water surrounded by ice and snow. 1/2500, f/6.3, ISO 400, 500 f/4, natural light Then the same bird flew off and then came back to land within a few feet of where it had been fishing – almost like it was…
Last week I came across this one-legged White-faced Ibis at Farmingtom Bay. Normally, these birds feed by slowly wading through the water and locating their invertebrate prey by tactile probing of the muddy substrate. Their long, recurved and extremely sensitive bill is an ideal tool for this purpose. But this bird, of course, is unable to wade. So it would stand in one spot for a few seconds while feeding and then jump to the next spot with great effort. The problem it had with this method was maintaining balance as it was landing in the new spot, since it couldn’t put down the missing leg for support. So, as it landed it would use that long bill as a sort of substitute for the missing leg and foot, thus gaining an additional balancing and support point in the mud. Here it has just regained balance and is closing its wings and pulling its long bill off of the mud. Perhaps what the bird was doing can be better visualised from this one photo, where you can tell from the turbulence around the right leg that the ibis has just landed in this spot a split second before and that it is using its long bill to brace itself in order to regain balance. And here I caught the ibis just as it was “landing” on a new feeding spot – the water is actually fairly deep here. I hope this post isn’t seen as much…
The American Bison is a relative newcomer to North America, having migrated from Eurasia over the Bering Straight about 10,000 years ago. As is common knowledge they once roamed in massive herds across most of the continent until commercial hunting and slaughter reduced their numbers to a few hundred by the end of the 19th century. 1/500, f/6.3, ISO 500, 500 f/4, 1.4 tc Today a herd of approximately 500 animals roams free on Antelope Island and that many large animals produce a lot of poop – commonly referred to as “buffalo chips”. Those chips are all over the island – like small dark islands in a sea of prairie grasses and tiny flowers and they’re tempting perches for a variety of bird species like Horned Larks and Meadowlarks. But this past week I was able to catch some larger birds using them as perches. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc In the spring some of the shorebirds and wading birds come up from the shore of the Great Salt Lake to higher ground on the island for their breeding activities – Long-billed Curlews among them. It seems that the added height of only a couple of inches provided by the chip is enough to significantly improve their view of the landscape for potential predators and also to help them keep an eye on other curlews in the area – there’s a lot of fighting and mating activities going on this time of year. To some viewers such a perch may have no aesthetic draw but I’m…
On December 12, 2007 I photographed this Common Goldeneye with a fish at Farmington Bay Wildlife Management Area. At the time I didn’t pay much attention to what kind of fish it might be and then just kind of forgot about it. Male Common Goldeneye with unidentified (at the time) fish The moment of capture Then, on October 2, 2008, I took some photos of a Snowy Egret fishing, also at Farmington. Finally, I became curious about the unusual fish – noticing the atypical elongated almost eel-like body in particular. I made some casual inquiries of refuge personnel about fish species present there but didn’t get anything definitive that would match this fish. More time went by, then I finally showed Justina Parsons-Bernstein some of the photos and asked her about the fish. She is the Director of The Great Salt Lake Nature Center at Farmington Bay WMA and she was also curious as to what species of fish it was so she sent some of my images to a vertebrate specialist with the state of Utah. He keyed it out as a Weather Loach. It turns out that the Weather Loach or Dojo Loach as it is also known (Misgurnus anguillicaudatus) is quite a remarkable fish. The name Weather Loach comes from the fact that it is highly sensitive to minor changes in barometric pressure and when it perceives such a change its behaviour becomes erratic, active and animated. Humans have kept them captive as a weather indicator for centuries. They are a very hardy species, capable of surviving poor conditions by swallowing atmospheric…
