Additions to the avifauna of Colombia

Abstract

The present list of additions to the colombian ornis consists entirely of specimens collected by the author, some of them taken during the period between 1915 and 1917 when collections were being made for the Carnegie Museum of Pittsburgh, U. S. A., on which no report was ever published, the remainder during his recent work for the U. S. National Museum between the year 1941 and 1952, iclusive. In a subsequent paper notes on the field work of the author in Colombia will be presented, together with unpublished records and comments on rare or little known species of birds of Colombia, which, it is hoped, will add considerably to our present knowledge of the distribution of these rare forms.
