Birds of Game Abundances in Evergreen Forests in Calakmul Biosphere Reserve, Campeche, Mexico

The Calakmul Biosphere Reserve (CBR) is in the south of the Yucatán Peninsula and is known for its great biological diversity. However, despite the great diversity of species, they are under intense pressure from hunting activities, especially the larger ones that can be used for human food. Therefore, the objective of this study was to obtain knowledge about the hunting importance of populations of three species of birds (Crax rubra, Meleagris ocellata, and Penelope purpurascens) in the southern zone of the Calakmul Biosphere Reserve, Campeche. Sampling was conducted with transects where a total of 46 camera traps were installed from November 2021 to November 2022, distributed in two types of vegetation. Likewise, data on species presence were collected and analyzed with Principal Component Analysis and ANOSIM (ANOSIM; R = 0.10, p = 0.22) to relate abundances with vegetation types and seasons of the year. No significant differences were found between the two vegetation types. This study provides relevant information on the populations of game birds in the southern region of Calakmul, which is currently little explored, and constant monitoring of these species throughout the CBR is necessary.
