In a study conducted between the months of July and December of 2012, two patches of tropical dry forest from the geographic valley of the Cauca river (Colindres-Jamundi and Las Chatas-Buga) were followed. To collect the data, point counts and transects were used; additionally mist nets were used for the recognition of small and inconspicuous birds. 2364 birds, corresponding to 1462 records, divided into 76 species, 27 families and 16 orders were observed. The family with the greatest number of species was Tyrannidae (14), followed by Thraupidae (seven), then Ardeidae (five) and Picidae (five). In the Chatas Forest 51 species, grouped among 20 families were found, while in the Colindres Forest 59 species, grouped among 25 families were found. The data presented, contributes to the knowledge regarding the actual diversity of the bird population that still exists in two of the few patches of tropical dry forest remaining in the geographic valley of the Cauca river, and its relationship with the size and type of matrix surrounding these patches. These data could be taken into account for the design of management and conservation strategies of the dry forest, to mitigate the damage done by the monoculture of sugarcane and human intervention in general, responsible for its high vulnerability.
Abstract (es):
En un estudio realizado durante los meses de julio a diciembre de 2012, se hizo seguimiento a dos parches de bosque seco tropical del valle geográfico del río Cauca (Colindres â Jamundí y Las Chatas â Buga). Para la recolección de los datos se utilizaron conteo por puntos y senderos y redes de niebla que permitieron reconocer aquellas aves inconspicuas. Se observaron 2364 aves, correspondientes a 1462 registros, distribuidas en 76 especies, 27 familias y 16 órdenes. La familia con mayor número de especies fue Tyrannidae (14) seguida de Thraupidae (siete), Ardeidae (cinco) y Picidae (cinco). En el bosque Las Chatas se encontraron 51 especies de aves, agrupadas en 20 familias; mientras que en el bosque Colindres se encontraron 59 especies, agrupadas en 25 familias. Los datos presentados contribuyen al conocimiento de la diversidad actual de la avifauna en dos de los pocos parches de bosque seco tropical que aún existen en el valle geográfico del río Cauca, y su relación con el tamaí±o y el tipo de matriz que rodea estos parches. Estos datos podrían tenerse en cuenta para el diseí±o de estrategias de manejo y conservación del bosque seco, que permitan mitigar el daí±o hecho por el monocultivo de caí±a de azúcar y en general la intervención antrópica, responsable de su alta vulnerabilidad.
