1. Ross's Geese Chen rossii, adult (left) and juvenile (right), Point Reyes National Seashore, Marin, California, USA, October 26, 2003. Note the short, stubby bills, the straight border to the base of the bill. The bluish area is especially noticeable on the adult. First-basic California Gull Larus californicus in the foreground.
2. Ross's Geese C. rossii, with Snow Goose C. caerulescens behind, Point Reyes National Seashore, Marin, California, USA, October 26, 2003. Overexposed, but an interesting comparison of the bill shapes of these two species.
