Knowledge about biodiversity in a natural protected area is essential for the development of actions for its management and conservation. The objective of this work was to determine the richness patterns, endemism categories, as well as the conservation and vulnerability status of birds in the Sierra del Abra Tanchipa Biosphere Reserve, located in the northeastern region of the state of San Luis Potosí, Mexico. The information generated by the community bird monitoring program and other sampling efforts in the area was included. Fieldwork was carried out based on the census method of counting by points established along transects in the study area. A total of 279 bird species belonging to 23 orders and 54 families were registered, of which the highest percentage are permanent resident species (64.16 %). Of the species recorded, 37 are under some risk category, and 25 species have some endemism category. 54.12 % of the species have a Neotropical affinity, 26.88 % a Nearctic one, and 19 % a Nearctic/Neotropical one. On the other hand, around 22.22 % of the registered birds have a medium to high sensitivity to disturbance, which may increase due to changes in habitats generated by human activities in the reserve’s area of influence. The community allies linked to the monitoring program contributed significantly to the field activities and the dissemination of the actions aimed at bird awareness in the reserve. The obtained data allow the updating of information in the management program of the natural protected area, which will favor the birds’ conservation in the zone.
