Range and Habitat
Pied-billed Grebe: Breeds from British Columbia, southern Northwest Territories, and Nova Scotia southward throughout North and Central Americas. Spends winters across the coastal and southern states, throughout Mexico and the West Indies or wherever water remains open. Preferred habitats include marshes and ponds.
Breeding and Nesting
Pied-billed Grebe: Two to ten light blue eggs are laid in a well-hidden floating nest made of dead marsh vegetation anchored to emergent plants. Incubation ranges from 23 to 27 days and is carried out by both parents.
Foraging and Feeding
Pied-billed Grebe: They are opportunistic as to the kind and size of prey, and take what is most readily available, including fish, crustaceans, especially crayfish, beetles, nymphs of dragonflies and aquatic insects and their larvae. They forage by diving from the surface and swimming underwater. They collect most food underwater during foraging dives.
Vocalization
Pied-billed Grebe: Emits a series of hollow cuckoo-like notes "cow-cow-cow-cow, cow, cow, cowp, cowp, cowp", that slows down at the end.
Similar Species
