Today’s weather was cloudy, with low visibility and light northwest winds. Despite the weather conditions, we had the arrival of a couple exciting birds. During the morning area search a group of five American Pipits were seen foraging on the marine terrace. Upon closer inspection, one of the pipits turned out to be of the japonicus subspecies, which breeds in Siberia. Maybe someday this subspecies will be promoted to full species status (one proposed name is Siberian Pipit). Note the bird’s pale, almost white, belly, bold white wing bars, dark, bold malar stripe and pale legs.

Less than an hour later, we had a Snow Goose fly over. It was flying near a couple Brown Pelicans, so we were able to judge its size, and rule out Ross’s Goose. Plus, we heard it honk and were able to get good looks at its large bill. The bird never landed, and wasn’t seen again. We believe this is the first Snow Goose seen on the island in a decade. It’s very interesting that a bird which is highly migratory and very abundant on the mainland, would be so rare out here.

Other new arrivals were: Northern Pintail, Green-winged Teal, Mew Gull, Short-eared Owl, Cliff Swallow, “Western” Palm Warbler, and Purple Finch.
