Avifauna en dos parches de bosque seco del departamento del Valle Cauca, Colombia
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.
