The biodiversity of birds in Pie de Palo Mountain is insufficientlyknown. The objective to the present work is described thebiodiversity and riches of birds. We sample in Las Flores gully, inJanuary, August and October of 2008. The method for collectedthe data was transects and sampled point. Then calculate theShannon – Wiener index and Jacquard’s similitude index forcomparator between months. The number of species of birds inthis work was 38 in 19 families. The Shannon – Whiner index andriches for each month was: 3.17 and 24 for January; 2.77 and 16for August, 2.99 and 20 for October, respectively.The months, October and January, form one group in the clusteranalysis with 37 percent of similitude, and August is more distantwith 28 percent of similitude with the first group.The categorization for IUCN of birds of Las Flores gully is:Harpyhaliaetus coronatus (Threatened), Vultur gryphus (NearThreatened), Progne modesta (Vulnerable D1) and the othersspecies was considerate as Least Concern.This work is the first contribution to biodiversity of the birds inPie de Palo Mountain.
