Southern Lapwing

The Southern Lapwing (Vanellus chilensis) is a wader in the family 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 River Plate. It has also been spreading through Central America in recent years.

It is a popular bird in Uruguay, where it is called tero. Due to the sound of the call the bird makes and its bold and pugnacious nature it has become the namesake and mascot of the Uruguay national rugby union team, Los Teros. In Brazil it is widely known as quero-quero, an onomatopoetic of its commonly heard voice.
