On birds from northern Colombia

Abstract

This paper reports on a collection of birds made by the senior author and Mr. Donald Beattie mainly in the Serranía de San Jacinto, Departamento Bolívar. This range of low mountaíns rep'resents the northernmost ,extension of the Western Andes of Colombia. The original vegetation cover of moist to dry tropical forests is still preserved in some of the deeply incised valleys and no previous ornithological studies had been made of the area.

The fauna is composed of Amazonian types, west-Andean elements and north-Colombia endemic species and indicates a former forest connection with the more humid forests in the lower Cauca and middle Magdalena valleys.
