Diversidad de aves de hábitats naturales y modificados en un paisaje de la Depresión Central de Chiapas, México

Sumario:In many parts of the neotropics, the original habitats are rapidly changing because of excessive logging, agriculture and livestock activity, with an often negative impact on bird communities. I present an analysis of the diversity and richness of birds in a fragmented landscape of the Central Chiapas Depression. Fieldwork was conducted from February 2003 to January 2004. Using point counts, a total of 35 families and 225 bird species were registered (164 residents and 61 migratory); 3% are abundant and 30% rare. Diversity, species richness and number of individuals were significantly higher in tropical deciduous forest (H ́=3.41, 178 species ANOVA p<0.0001), which also had the greatest number of species restricted to a single vegetation type (39 species). The incorporation and maintenance of natural and modified habitats are necessary for the survival and reproduction of many birds species in the study area.
