Yesterday morning I found this Willet perched on one of the Tintic Quartzite boulders so common on the northern part of Antelope Island. The Willets are still active on the higher slopes of the island but it won’t be long until they’re spending most of their time along the shoreline and causeway.
On my mid-July trip to the Centennial Valley I spent several days with an adult Willet and two juveniles. I reliably found them foraging for insects where a dirt road met Lower Red Rock Lake. Most of the shore birds and wading birds in this area are truly wild and difficult to approach but these three birds were the exception as they repeatedly let me get close as they fed and preened. 1/2500, f/7.1, ISO 400, 500 f/4 This was the most perfectly coiffed of the two juveniles, as the other youngster had a patch of unruly feathers on the back of its head and upper neck. 1/2500, f/7.1, ISO 500, 500 f/4 This particular site provided a bountiful Arthropod smorgasbord for the willets, both in the water and on the shoreline. The birds would feed on aquatic insects and crustaceans in the shallow water for a while and then get a little variety in their diet by coming up onto the shore and gobbling down hordes of terrestrial insects. Here, the more unkempt juvie (notice the fluff of feathers on the back of the head) feeds on a variety of dipterans that it flushes from the vegetation. I’ve cropped this image unconventionally to show more of the “bugs” in the air. I didn’t get a catch light in this shot but this image showed the insects best. 1/2000, f/7.1, ISO 400, 500 f/4. 1.4 tc At times some of the insects almost seemed to dare the Willets to pluck them out of…
Last summer at Red Rock Lakes National Wildlife Refuge I slowly approached this bathing Willet in my pickup, fully expecting the bird to either fly off or wander further away in the shallow water of Lower Red Rock Lake. 1/2000, f/8, ISO 400, 500 f/4, 1.4 tc It eyed me warily until I had turned off the engine… 1/2000, f/8, ISO 400, 500 f/4, 1.4 tc but it was so intent on its bath that it quickly went back to minding its hygiene. 1/3200, f/7.1, ISO 400, 500 f/4, 1.4 tc For this shot the Willet turned its back on me a little but I liked the shot because it shows the furious action at the rear of the bird. 1/2500, f/7.1, ISO 400, 500 f/4, 1.4 tc With water and feathers flying everywhere… 1/3200, f/7.1, ISO 400, 500 f/4, 1.4 tc it finally gave me a bit of a head turn again as it spread and raised its tail feathers for a good cleaning. 1/3200, f/7.1, ISO 400, 500 f/4 Then it hopped up on the shore for a vigorous shake. 1/4000, f/7.1, ISO 400, 500 f/4 By this time it had approached me so closely that I had to take off my teleconverter but even so I was tight enough on the bird that I wasn’t able to get the composition I would have preferred for these last three shots. 1/3200, f/7.1, ISO 400,…
My last few visits to Antelope Island have yielded a mixed bag of bird and mammal photos that I enjoy so I thought I’d share a little of what it’s like to experience the wildlife out there during late spring. Canon 7D, 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc This take-off pose is one I’ve been after for some time so I was glad to get it from this Loggerhead Shrike, despite the foreground twig in front of the right wing-tip. Canon 7D, 1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc I believe this to be the same bird as in the previous photo. It had captured what I think was one of the Ichneumon wasps and toyed with it a while before dropping it. I was happy to get the wasp unobscured by the branches or the birds toes as it fell. The shrike watched where it fell and retrieved it. Canon 7D, 1/2000, f/6.3, ISO 640, 500 f/4, 1.4 tc There are presumably many pronghorn fawns on the island this time of year but I’ve found it difficult to get close to them or even to spot them at a distance – probably partially due to their instinctive behavior of lying low in the tall grasses much of the time. This one was in a playful mood and spent several minutes romping through the grass around its mother. Canon 7D, 1/2500, f/6.3, ISO 640, 500 f/4, 1.4 tc This is the same fawn a few minutes later, just after nursing. …
Yesterday I got a shot of a Willet expelling a pellet. It’s a behavior I’ve seldom seen and rarely photographed because it typically happens very quickly, many birds don’t do it at all and it often occurs only once per day or so with many species. A pellet, sometimes referred to as a bolus, is a clump of indigestible material that is formed in the crop and eventually regurgitated. Depending on the diet of the bird it may be made of feather, bone, fur and/or chitin from insect or crustacean exoskeletons. Canon 7D, 1/4000, f/6.3, ISO 500, 500 f/4, 1.4 tc At first I wasn’t taking many photos of this Willet because its lower legs were cut off by the rock perch but I did adjust my settings for quick action in case it took off or performed some other interesting behavior. Canon 7D, 1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc The first indication I got that something might happen that would be interesting to photograph was when the bird pulled down its neck and there was a slight bulge in the throat. Canon 7D, 1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc Then the Willet began trying to expel the pellet. Canon 7D, 1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc What happens next appears to look almost like a gagging reflex. Canon 7D, 1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc The pellet popped out so quickly that I didn’t even see it through the viewfinder…
Earlier this week Mia and I witnessed an incredible display of avian aggression on Antelope Island. I’ve often seen and photographed battling birds but I’ve never before seen such a long-lasting and vicious fight as this one between two Willets. It lasted for over 20 minutes and I took 413 photos of the action but don’t expect high quality images in this post as the conditions were far from ideal. We had contrasty sidelight, lots of obstructingvegetation between us and the birds and constantly changing lighting conditions as clouds moved in and out and the birds moved from place to place as the battle raged. But as I’ve stated before on this blog I’ll often post images of interesting behaviors even if they are less than perfect in image quality. And to me this behavior was certainly interesting. Canon 7D, 500 f/4, 1.4 tc, 1/1600, f/5.6, ISO 500 The Willets were already fighting as we approached them in my pickup and they mostly ignored us after pausing for a few seconds when we first drove up. Canon 7D, 500 f/4, 1.4 tc, 1/1250, f/5.6, ISO 500 In this and the following image the bird on the right had its bill tightly clamped on the upper mandible of the other bird. Canon 7D, 500 f/4, 1.4 tc, 1/1250, f/5.6, ISO 500 The bird on the left was desperately trying to break the grip of its tormentor but it took some struggling before it finally succeeded. Canon 7D, 500 f/4, 1.4 tc, 1/1250, f/5.6, ISO…
