Breeding and Nesting

Osprey (Palau): Three pink or white eggs marked with olive and brown are laid in a bulky nest made of sticks and lined with bark, sod, grasses, vines, algae or flotsam and jetsam. Nests are usually built on snags, treetops, or crotches between large branches and trunks. They sometimes nest in loose colonies. Incubation ranges from 35 to 40 days and is carried out by both parents.

Foraging and Feeding

Osprey (Palau): They feed exclusively on fish, usually twice daily. They forage by flying over water, hovering once prey is spotted, then diving into the water feet-first to grasp prey; sometimes they lay on the water and rest. They forage along coasts in salt-water marshes, lagoons and ponds, estuaries, silted river mouths and coral reefs. Ospreys do not cache food.

Vocalization

Osprey (Palau): Species has eight vocalizations, though these are usually only produced near nesting sites. This bird is relatively silent elsewhere. Alarm call is a descending "tooup, tooup, tooup."
