Description
Abstract. -- This study examined the avifauna of three vegetational communities of the Sierra San Antonio-Pena Nevada of northeastern Mexico, from June 2001 to May 2002. A total of 1,084 individuals were recorded, comprising 83 species, 62 genera, 31 families and 9 orders. The ecological associations of the species were as follows: Pine 40; Pine-Oak 48; and Oak 58. The seasonal distribution of the species was: Spring 48; Summer 42; Fall 47; and Winter 40. Based on the Shannon's Diversity Index, the highest values were obtained for Oak Forest (H' = 3.16) and for Spring (H' = 3.26).
