Primeros registros de anidación de la alondra cornuda (Eremophila alpestris peregrina) en Colombia

Abstract

Eremophila alpestris is a widely distributed species in temperate zones, with a single tropical population restricted to the high elevation plateau of Cundinamarca and Boyacá in Colombia. This population constitutes a distinct subspecies E. a. peregrina, which is considered endangered. We present the first nesting records for this subspecies from the area of the La Copa Reservoir, Boyacá Department, where we found four nests with eggs and chicks in April 2005. We also describe information on a nest and egg deposited in a museum collection. The general characteristics of the nests agree with those reported for Holarctic populations, although clutch size is smaller than in populations at higher latitudes.
