Tricolored Blackbird (Agelaius tricolor)
The Tricolored Blackbird (Agelaius tricolor) has been recognized as a focal species due to its restricted range (entire global population within North America, at least 95% of population located in California with small breeding colonies in Oregon, Washington, Nevada and Baja California), overall severe decline in population beginning before the 1930s, heightened vulnerability due to colonial nesting behavior, and losses of both nesting and foraging habitats.
