Vanellus chilensis
The southern lapwing (Vanellus chilensis) is a wader in the order Charadriiformes. It is a common and widespread resident throughout South America, except in densely forested regions (e.g. most of the Amazon), the higher parts of the Andes and the arid coast of a large part of western South America. This bird is particularly common in the basin of the Rio de la Plata. It has also been spreading through Central America in recent years. It reached Trinidad in 1961 and Tobago in 1974, and has rapidly increased on both islands, sporadically making its way North to Barbados where one pair mated, nested and produced chicks in 2007.
The southern lapwing is the national bird of Uruguay, and one of the symbols of the Brazilian state Rio Grande do Sul.
