Pied-billed Grebe

Description:

Pied-billed Grebes are small, chunky swimming birds. They have compact bodies and slender necks, with relatively large, blocky heads and short, thick bills. They have virtually no tail. These are brown birds, slightly darker above and more tawny-brown on the underparts. During spring and summer, the crown and nape are dark and the throat is black. While breeding, the bill is whitish with a black band (“pied’), but otherwise is yellow-brown. Juveniles have striped faces.

Habitat:

Sweetwater Wetlands

Notes:

Pied-billed Grebes can trap water in their feathers, giving them great control over their buoyancy. They can sink deeply or stay just at or below the surface, exposing as much or as little of the body as they wish. The water-trapping ability may also aid in the pursuit of prey by reducing drag in turbulent water. Like other grebes, the Pied-billed Grebe eats large quantities of its own feathers. Feathers may at times fill up more than half of a grebe’s stomach, and they are sometimes fed to newly hatched chicks. The ingested plumage appears to form a sieve-like plug that prevents hard, potentially harmful prey parts from passing into the intestine, and it helps form indigestible items into pellets which they can regurgitate. When in danger, Pied-billed Grebes sometimes make a dramatic “crash-dive” to get away. A crash-diving grebe pushes its body down with its wings thrust outward. Its tail and head disappears last, while the bird kicks water several feet into the air.
