Birds at East Park Reservoir
The tricolored Blackbird is abundant at the reservoir, with three breeding colonies found around the reservoir. The area around East Park Reservoir is one of the best sites in the state to observe this declining species. The California endemic Yellow-billed Magpie also breeds at the reservoir and the watch-listed Oak Titmouse is quite common in the riparian and blue oak habitats. Lawrence's Goldfinch has also been confirmed as a breeding species. While the goldfinch is rarely seen at East Park in the spring, it has been sighted on occasion during the summer months. The number of goldfinch sightings has decreased in recent years---in fact, there were no sightings at East Park in all the 1999 (PRBO 2000). The Audubon's watch-listed Nuttall's Woodpecker is common and conspicuous in the reservoir's riparian habitats. Audubon Watch List species are those faced with population decline, limited geographic range, and/or threats such as habitat loss on their breeding and wintering grounds. The area is also used as a stopover point by migrating land birds (ABC 2001).
