Today at Sweetwater Wetlands I found a 1st-year Golden-crowned Sparrow in the river associating loosely with a flock of White-crowned Sparrows. I was able to call Andrew Core, grab my camera, and refind the bird to capture these shots. While snapping pictures I heard a rustling in the leaf litter and noticed a large (for this area anyway) 4.5 foot Western Diamondback Rattlesnake about 3 feet from my feet (also pictured below)! When I moved it stopped suddenly, but then went on its way in a few minutes hardly even remembering my presence.
