Heterogeneous environments predominate in tropical landscapes, then studying diversity and composition of species in avian communities has allowed understand how it vary and is structured. This information also allows implementing management and conservation strategies in these environments. This study evaluated the diversity and spatial and temporal composition of the bird community in Lagunas de Montebello National Park, Chiapas, in different types of forests and conditions (pine forests, pine-oak, pine-oak-liquidambar, mountain cloud forest, riparian vegetation and modified areas). Sampling was carried out from February to July 2017 at 110 counting points every 300 m. In total, 3,143 birds of 123 species were recorded. The diversity measured with the order q= 1 was 41.67 and with q= 2 it was 24.79 effective species. Rainy season showed greater species diversity than dry season. The best represented guilds were granivores-frugivores-insectivores, insectivores and omnivores. The modified areas, as well as pine forest and riparian vegetation areas had the greatest diversity of species. In contrast, mountain cloud forest, pine-oak-liquidambar, and pine-oak forests had rare and vulnerable species such as Golden-cheeked Warbler, Resplendent Quetzal, and Highland Guan. This study allows to identify sites for monitoring and forest management that will allow for better planning in the national park.
