General

Morningbird: Small, dull, gray-brown whistler species with a buff-brown belly and vent, and some buff-brown edging to the feathers in the wings. It has a black-brown eye, short wings, and a thick, straight, gray-brown bill. The tail is medium in length with a slightly notched tip. Medium-length legs and feet are black-gray. This Palau endemic feeds on insects, snails, seeds, berries, and other small fruits. Forages in trees by picking food items off of leaves and branches with its bill.

Breeding and Nesting

Morningbird: Nothing is known about the breeding behavior of this species but is expected to be similar to that of other whistlers. The related Olive Whistler lays two to three buff eggs with purple and brown spots in a fragile cup-shaped nest constructed with strips of bark, grass, twigs, and spiderwebs. Both sexes incubate the eggs for 15 days.

Foraging and Feeding

Morningbird: Feeds on insects, snails, seeds, and berries and other small fruits. This whistler species forages by picking food items off of leaves, branches, and twigs with its bill. It does not sally out from a perch to catch insects.

Vocalization

Morningbird: Emits a harsh, raspy call. Song is a mixed warbling of chirps and whistles.

Birds do not have two separate cavities for excrement and reproduction like humans do. In birds, there is one single entrance/exit that suits both functions called the vent, cloaca or anus.
