Southern Lapwing (Vanellus chilensis) Science Article 1
abstract
Despite its wide distribution throughout most of South America, the Southern Lapwing (Vanellus chilensis) remains poorly studied, and even the most basic aspects of its natural history have been only briefly reported. According to Johnsgard (1981) four subspecies are recognized, of which. only cayennensis occurs at the extreme northern border of the species range. With the exception of brief descriptions of nests and eggs (e.g., Dalgleish 1881, Euler 1900, Ihering 1900, Chubb 1910), a few notes on timing (see Hilty & Brown 1986), and evidence of cooperative breeding under conditions of habitat saturation (Walters 1980), little published information on reproduction of this geographical form is available
