Strange ducks perched on the trees along the Rio Tarcoles—Muscovy Ducks. Wild Muscovy Ducks range from Mexico south Argentina. Some may wander into the United States. The problem is that feral Muscovy Ducks have been introduced around the world, sort of like chickens and pigeons. Birds in Texas and Florida are probably escaped domestic individuals. One result is that the feral birds are highly variable in plumage and probably should not be counted on birders’ lists.
Muscovy Ducks appeared to be fairly common in Costa Rica. Many roosted in riverside trees as we returned to the dock in the gathering dusk. Across their range, their numbers appear to be somewhat variable. Often populations suffer from over-hunting, egg collecting, and hybridization with domestic populations (Handbook of Birds of the World).
