Savannah Sparrow With A Mouthful Of Insects
Savannah Sparrows With “Bugs” For Their Nestlings
Savannah Sparrows are incredibly efficient hunters while they’re feeding nestlings or fledglings.
Savannah Sparrow Feeding Fledgling
During our last Montana trip we had multiple sessions over several days with a very cooperative Savannah Sparrow – “cooperative” in the sense that the bird could always be found in the same spot along the shore of Lower Red Rock Lake in Red Rock Lakes National Wildlife Refuge.
Savannah Sparrow – Fearless Dragon Slayer
This little Savannah Sparrow was one of my most memorable birds on our recent Montana camping trip. It was a fearless and a relentless hunter.
Just A Shot That I Like… # 27, Savannah Sparrow Wing Stretch
So very often when an avian subject gives the photographer a nice wing stretch the bird is either facing away or there’s no light on the face. So I always appreciate it when things work out with a shot like that. 1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc This Savannah Sparrow (along with several others of various species) would forage in the Montana pasture grass for a while and then return to the barbed wire to preen and occasionally stretch. I like the diaphanous qualities of the right wing that allow the viewer to see the fanned tail and stretched out foot and leg through the wing feathers. Ron
Savannah Sparrow Parasitized By Cowbirds
Brown-headed Cowbirds are well-known for laying their eggs in the nests of other species – brood parasitism. A single cowbird female may lay up to 40 eggs in the nests of other species per season. More than 220 host species have been identified and at least 144 of those species have successfully raised the parasitic cowbird offspring. The physical size of the host species ranges from tiny 10 gram creepers to 150 gram meadowlarks. For a variety of reasons, the young of the parasitic cowbirds are more likely to survive than are those of the host species. The breeding success of the rare Kirtland’s Warbler has been severely reduced by cowbird brood parasitism. 1/1600 f/7.1, ISO 400, 500 f/4 On our recent trip to sw Montana we found this Savannah Sparrow bringing food (insects, mostly young grasshoppers) to one of its fledglings on a fence near our campground. 1/1600 f/6.3, ISO 400, 500 f/4 But the fledgling was a cowbird and not a Savannah Sparrow. Cowbirds are more than twice the size of Savannah Sparrows by weight and that difference is obvious here. 1/1600 f/7.1, ISO 400, 500 f/4 The cowbird youngster was boisterous and rambunctious when food was brought in. I actually had the impression that the adult sparrow was a little intimidated by the size and hyperactivity of the cowbird chick and the “parent” bird didn’t stick around for long when food was delivered. 1/1600 f/7.1, ISO 400, 500 f/4 After the chick swallowed this grasshopper the sparrow gave it another…
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…
