Habitat characteristics and nest success of snowy plovers associated with California least tern colonies Habitat characteristics and nest success of snowy plovers associated with California least tern colonies
Nest success of Snowy Plovers (Charadrius alexandrinus) was estimated at six sites in San Diego County, California, to determine the effects of habitat characteristics and social factors on predation risk. Egg predation was expected to be lower for plovers nesting among Least Terns (Sterna antillarum) because of benefits associated with nesting under the “protective umbrella” of a...

Habitat use and reproductive success of western snowy plovers at new nesting areas created for California least terns Habitat use and reproductive success of western snowy plovers at new nesting areas created for California least terns
The Pacific coast population of western snowy plovers (Charadrius alexandrinus nivosus) was listed as threatened under the Endangered Species Act (ESA) in 1993 and its decline is primarily attributed to habitat loss. In southern California, snowy plovers typically nest in association with federally endangered California least terns (Sterna antillarum browni). Since least terns were...

Nesting habitat of Belding’s Savannah sparrows in coastal salt marshes Nesting habitat of Belding’s Savannah sparrows in coastal salt marshes
Although the Belding’s Savannah sparrow (Passerculus sandwichensis beldingl) is listed as endangered in California, little is known about the factors that affect its abundance and distribution. Numbers of breeding pairs, nesting territory sizes, and vegetation characteristics were measured at fourteen study plots in two southern California coastal wetlands, Tijuana Estuary and Los...
