Savannah Sparrows – a Bug’s Worst Enemy

On a recent camping trip to Red Rock Lakes National Wildlife Refuge a rustic old fence near where we camped was the staging area for several hunting Savannah Sparrows.   They obviously had nests in the grass nearby and would regularly perch on the fence with prey in their beaks after hunting deep in the grasses.      Canon 7D, 1/2500, f/7.1, ISO 640, EV -0.33, 500 f/4, 1.4 tc Boy, did they eat a lot of bugs!  Most any kind of Arthropod seemed to be an acceptable part of their diet but this critter was one of their favorites.  I believe it to be a dragonfly larvae.     Canon 7D, 1/800, f/6.3, ISO 640, EV +0.33, 500 f/4, 1.4 tc When they returned to the fence line they would often have multiple prey in their beaks.  I expected them to either immediately consume it or deliver it to the nest but that seldom happened.  Instead they would typically hang around on the fence for extended periods of time with the prey still in their beaks – often for 10 minutes or more before eating it or flying off to their nest with it.  I can’t explain the behavior but I’m certainly not complaining about it because that little behavioral quirk gave me many opportunities to photograph them with their bills full of interesting tidbits.      Canon 7D, 1/2000, f/7.1, ISO 500, EV +0.00, 500 f/4, 1.4 tc Their diet wasn’t limited to insects either, as it wasn’t unusual to see them with spiders.      Canon…

White-crowned Sparrow Bathing in a Lilac Bush

 I have a serious case of unrequited spring fever.  It’s been a long and dreary winter and it’s not over yet so when I stumbled across these images from last spring a few days ago I decided they were worthy of a post.   Canon 7D, 1.4 tc,  tripod, 1/2500, f/8, ISO 640 It was just after a spring rain in May last year when the sun came out and I noticed this male White-crowned Sparrow fluttering around in my neighbor’s lilac bush so I quickly grabbed my gear and started firing away.      Canon 7D, 1.4 tc,  tripod, 1/3200, f/8, ISO 640 The sparrow seemed so ecstatic over his bath that he let me get close and pretty much ignored me.      Canon 7D, 1.4 tc,  tripod, 1/2500, f/8, ISO 640 The leaves and especially the flowers were loaded with water and the sparrow was taking full advantage of the situation.      Canon 7D, 1.4 tc,  tripod, 1/2000, f/8, ISO 640 And the ecstasy continues.  I guess there’s just something special about bathing in lilac water…      Canon 7D, 1.4 tc,  tripod, 1/2000, f/8, ISO 640      Canon 7D, 1.4 tc,  tripod, 1/2000, f/8, ISO 640      Canon 7D, 1.4 tc,  tripod, 1/2500, f/8, ISO 640     Canon 7D, 1.4 tc,  tripod, 1/2500, f/8, ISO 640 Some of these photos are far from perfect – the light was harsh, the bird was side-lit, I often didn’t get a catch light in the eye and the contrast was high, especially…

Photographing Birds on Antelope Island

  My previous post was an overview of the geology of Antelope Island and its non-bird wildlife.  Here, I’ll focus on its birds.   Juvenile Loggerhead Shrike begging for food Loggerhead Shrikes are common on many parts of the island during summer.  They can be a challenge to approach but those few that nest close to the road eventually get used to traffic so if you photograph from your vehicle you can often get quite close.  Here this juvenile was begging for food that was being delivered by a parent just out of frame to the left.    Loggerhead Shrike with dragonfly  Shrikes are often called “butcher birds” for their practice of temporarily impaling their prey on thorns or other sharp projections.   This juvenile had done just that with the dragonfly but it wasn’t very good at it yet and in the end just decided to eat it instead of store it away.     Loggerhead Shrike with spider Shrikes are opportunistic carnivores known to feed on insects, spiders, amphibians, small reptiles, rodents and other birds.   This one also attempted to impale the prey before eating it.     Juvenile Burrowing Owl practicing its parallax technique on me Burrowing Owls are one of my favorite species on the island though they can be difficult to locate from year to year as they often don’t seem to nest in the same burrow the next year.  In the summer of 2009 there was an entire family of owls along the causeway to the island nesting under concrete rubble, as in the…
