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