The moment I pulled up on this small pond at Bear River Migratory Bird Refuge last Friday I knew there’d be some opportunities for interesting behavioral shots. There were small groups of American Avocets and Black-necked Stilts that were excitedly chirping away and flying at each other in typical springtime behavior for these mixed flocks.
Having witnessed the rituals of avocets mating many times before I knew what was about to happen when this female laid her bill down on the water’s surface and presented herself to the male. This time I got the shot. So often in the past they’ve had their backs to me when it happened.
American Avocets have always been a very difficult flight shot for me so I only have a couple of them in my files. I think one of the factors that makes them so challenging in the air is their tendency for erratic flight. 1/3200, f/7.1, ISO 500, 500 f/4, 1.4 tc This was a grab shot taken at Glover Pond in Farmington, Utah. I like the slightly open bill and the position of the wings. This is a species that I too often ignore, whether the bird is in flight or wading. There’s just so many of them around here for much of the year that my tendency is to bypass them for more elusive subjects. Another bad habit of mine… Ron
Wednesday of this past week was my “medicare birthday”. I’m sure older readers will understand why my psyche needed some bolstering and I felt justified in burning up some extra gas and putting even more miles on my pickup for a trip to Bear River Migratory Bird Refuge to help take my mind off of my advancing age. It was worth the trip! While I didn’t get any truly spectacular shots it was a wonderful morning with excellent weather and light, lots of cooperative birds and great company – thanks to Mia. The only downside was that I had 35 gigs of images to cull when I got home… A couple of notes about my techs: a), regular readers are probably aware that I nearly always shoot with the 1.4 tc attached to my 500 mm. On this morning I got so close to many of the birds that almost half of the images I’ve posted here were taken without the tc and b), many of these images were taken with a very high shutter speed which is typical for me since I’m usually set up for action shots after firing off a few times on more traditional poses. All photos are presented in the order they were taken. 1/1250, f/5.6, ISO 640, 500 f/4, 1.4 tc On the road to the refuge we came across a pair of Short-eared Owls cavorting in the air right after the sun came up. One of the owls was “sky dancing” but by the time I got the pickup…
These images were all taken over the last eight days, either at Bear River Migratory Bird Refuge or Antelope Island. Another one of my “potpourri” posts with no common theme except “feathers”. 1/640, f/7.1, ISO 640, 500 f/4 The Willets have finally come up on the island for their mating activities (as opposed to the shoreline for recuperation after migration) and I like to try to catch them perched high on the sagebrush where they call loudly to other Willets. 1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc Western Meadowlarks are in their glory right now and their distinctive songs reverberate all over the island. 1/5000, f/6.3, ISO 500, 500 f/4, 1.4 tc I got closer to this one than I usually can. 1/1600, f/7.1, ISO 500, 500 f/4 This Loggerhead Shrike was grooming peacefully when I noticed a distinct change in its behavior. 1/1250, f/7.1, ISO 500, 500 f/4 A Common Raven flew low overhead and this was the shrike’s reaction. It flattened its body out almost into a bullet shape and pointed that bullet at the raven as it passed. I’m guessing it was an instinctive behavior to present the smallest profile possible to a larger bird that might be a potential threat. It was comical to watch it turn as the raven flew by to keep its body pointed in the larger birds direction. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc I’m always happy to catch a Chukar perched on a boulder, especially when it isn’t one of the…
Occasionally an image still appeals to me despite significant imperfections. In this shot the cluttered background is not ideal nor are the specular highlights on the leg of the male’s reflection but I quite like the positions of both birds, their reflections and the good separation between the avocets and the reflections. 1/1250, f/10, ISO 400, 500 f/4, 1.4 tc Fighting avocets are very difficult to photograph because typically several male combatants are separated from each other by some distance and you never know which bird is going to go after another one next and when the action begins it is blindingly fast. There’s also the problem of getting enough shutter speed and depth of field for multiple birds in action. Shooting these birds fighting is nearly always a “poke and hope” situation. Setting the scene: I had been photographing four males fighting over a single female (sexes easily identifiable because the female has a shorter and more strongly recurved bill than does the male) when this male lifted off and attacked two other males just out of frame to the right. I just happened to catch the male in a good position over the female with reflections I liked. One of the things that made this shot work is that I had enough light to use f/10 for sufficient depth of field and still get a fast enough (just barely) shutter speed to get both birds relatively sharp.

The Great Salt Lake in northern Utah is a vital resource for many of North America’s birds. The lake is 75 miles long, 30 miles wide and has 1680 square miles of surface area and 335 miles of shoreline. Surrounding the lake are 400,000 acres of wetlands. Roughly 5 million birds of 257 species rely on the lake and those wetlands for food, sanctuary, breeding and as a migratory stopover. And one of the primary reasons the lake is such an asset for them is the endemic brine fly, Ephydra hians. Brine flies can be intimidating because of their massive numbers but they are truly innocuous. They are found only within a few feet of the shore, they don’t bite and won’t even land on humans. And they’re a huge nutritional resource for birds. In the photo above, the blurry brown bits in the background are brine flies in flight that have been stirred up by the feeding California Gull. Different bird species have varying feeding methods with these flies – this species often stakes out a few feet of feeding territory on the shoreline and then rushes through the hordes of flies on the sand, stirring them up, and then snaps them out of the air in large numbers. This bird is looking down the shoreline and preparing for its next run on the flies. Most of the flies are resting on the sand until the bird makes its run. As the gull rushes along the shoreline the flies are disturbed into the air and the bird snaps…
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…
Recently I’ve been tardy in posting on this blog because Mia and I just recently returned from one of our favorite camping/photo destinations – four days at Red Rock Lakes National Wildlife Refuge. This trip was a memorable one (as they always are at RRL). Canon 40D, 1/200, f/16, ISO 500 @35mm, ev 0.0 5:30 pm. We were photographing American Avocets and Wilson’s Phalaropes on one of the refuge ponds when we looked behind us to the west and saw this impressive storm heading our way. It was really dumping on the foothills surrounding the valley and we figured things might get interesting so we decided to stay at the pond and see what happened. Good thing we were shooting from my pickup or we’d have been in trouble… Canon 40D, 1/250, f/16, ISO 500 @17mm, ev +0.33 5:52 pm. The slow-moving storm took a while to get to us but when it did it was impressive. It began to rain very hard. It was so intense that neither of us could keep water off of our lenses – in spite of the 7″ long hood on the end of my 500mm lens. I love my new Ford F-150 pickup but the engineers did a poor job on the roof rain channels and water simply poured in off the roof whenever a window was down. As you can see in my side mirror, Mia (who shoots from the back seat) has taken a temporary respite from the downpour and has her lens pulled in and her window…
I’ve spent many, many hours watching and photographing feeding avocets and have never once seen one eat a fish or even attempt to catch one that I was aware of. Until yesterday. American Avocet feeding on fish at Bear River MBR While at Bear River Migratory Bird Refuge I photographed this avocet catching, manipulating and finally swallowing a fish. I know that this behavior is not unheard of as Birds of North America Online (BNA) states that this species sometimes eats fish and my friend Dave Sparks once posted an avocet with a fish on an online critique forum. However, for me it was something new and unique and worthy of a post here. Ron
