Breeding and Nesting

Whimbrel (Palau): These birds live on the tundra during breeding season. Three to five olive to buff eggs tinted with brown and lavender are laid in a shallow depression lined with soft grasses, mosses and lichens. Both parents incubate the eggs for about 28 days and care for the chicks until they fledge, 34 to 42 days after hatching.

Foraging and Feeding

Whimbrel (Palau): They have a broad diet which includes marine invertebrates such as brachyuran crabs and other crustaceans, marine worms and mollusks, and also fish. They are visual foragers. It probes deeply into the mud and moves as it feeds. They also pick up food found on the ground. They sometimes take large prey, tearing it into pieces small enough to eat.

Vocalization

Whimbrel (Palau): Emits a series of loud, clear whistles "pip-pip-pip-pip-pip." Alarmed pairs will produce a trilling call.
