AVIAN DYNAMICS OF A CHIHUAHUAN DESERT CREOSOTEBUSH (LARREA TRIDENTATA) COMMUNITY IN NUEVO LEON, MEXICO

摘要

This study examined the avifauna of a Chihuahuan Desert creosotebush community in the state of Nuevo Leon in northeastern Mexico from May 1995 to April 1996. Based upon foraging strategies, the 48 species recorded were grouped into seven functional Groups (or guilds) which were further divided into 12 subgroups. The diversity of foraging Strategies was found to be high in this area of Nevo Leon and is compared with other Localities in the Chihuahuan Desert. Due to its richness and umber of functional subgroups, This area represents an important site in the avian diversity of the Chihuahuan Desert.
