Knowing the diversity and distribution of birds from a natural protected area can contribute to the development of conservation actions. Here we report the check-list of bird observed in Los Mármoles National Park, Hidalgo, Mexico. Count points and transects were used for recording diurnal birds, and listening stations for nocturnal birds; 195 species were registered. The total species richness included 137 resident species, 44 winter visitors, eight transient migrants, and six summer migrants. Richness varied between vegetation (forest) types, with 91 species found in Pinus-Quercus forests, 64 species in Juniperus forests, and 57 species in Quercus forests. Fifteen species are under some risk category and 26 species were endemic to Mexico. The diversity registered in Los Mármoles represents 38% of the birds known from the Hidalgo State and nearly 17% of the birds known from Mexico.
