Western Gull, Larus occidentalis
The Western gull, Larus occidentalis, is a large white-headed gull common along the western coast of North America. The Western gull ranges from British Columbia to Baja California. It is exclusively marine, and nests on offshore rocks and islands. While offshore it feeds on fishes and invertebrates that it can take at the surface (it cannot dive), and will scavenge carcasses and shellfish while foraging along the shore. It is known to predate upon other smaller birds. Western gulls have a lifespan up to about 25 years, although 15-20 years is more common.
