Shorebirds
Black
Oystercatcher
The global population is estimated to number fewer
than 11,000 individuals. Over half of these nest in Alaska, concentrated especially
in Prince William Sound and the Kodiak Archipelago (Andres
and Falxa 1995). Oystercatchers are completely dependent upon a narrow coastal
area throughout their life cycle, where they are highly susceptible to oil spills.
Their strong fidelity to breeding territories, easy accessibility, conspicuous
behavior, and limited reproductive potential (at most three young raised per pair
per year) also make them particularly vulnerable to local extirpation through
persistent disturbance by foxes and humans (Andres
1997, 1998). Subsistence harvest of either breeding adults or eggs is a potential
threat to some local populations of this species in Alaska.
