Trinidad: Southern Lapwing - Vanellus chilensis

On several occasions our group go to see small flocks of Southern Lapwings, Vanellus chilensis. This large "shorebird" prefers grassy Savannah's and marshes, and like the Killdeer and other plovers is not shy about displaying its handsome looks. Note the striking red iris, bronzy shoulder patch, trailing black crest, and black face, neck and breast. Unmistakeable! The name "lapwing" apparently has nothing to do with the structure of the wing but refers to the wavering flight pattern.
