Resumen
The Andean forest in Colombia has suffered heavy human pressures leading to an accelerated transformation of land use. For this reason, currently the Andean ecosystems are immersed in a matrix of heterogeneous landscape, these forest fragments still retain the great biodiversity of species distributed in the Andean zone. Bangsia aureocincta y Bangsia melanochlamys are endemic and endangered species of Colombia, with very little information about their habitat, life history, population size, ecological, etc. During the study period developed between January to April 2016 ecological information on population size, aspects of habitat use and diet of these endangered mountain tanagers in Montezuma, Tatamá Natural National Park was obtained. Also vegetation plots were performed to characterize the structure of the vegetation of the sampled forests. It was found that the gold-ringed tanager species present a similar density between the months of sampling of 3.35 ± 1.56 to 3.2 ± 1.2 individuals / ha with a greater presence during the first months of the year; and it was equal to B. melanochlamys where the density was higher at the beginning of the year with 4.15 ± 0.56 individuals / ha. The Bangsia of Tatamá, was present in dense rainforest, especially in the presence of moss and bromeliads soon intervened and high canopy areas also could be observed that this species is associated with certain plant families, such as Asteraceae, Rubiaceae, Fabaceae and Rutaceae. Bangsia black and gold was observed in some disturbed areas, and was more common to observe within the dense and humid forest; eventually made use of secondary areas and disturbed areas with many woody plants, it is also common presence in the middle of the tree layer, and was associated with certain plant families, such as Rubiaceae, Melastomataceae, Meliaceae, and Ericaceae. Population densities for both species show that the study area has a vertically and horizontally which supplies good and sufficient resources to these plant species Bangsias heterogeneous structure. Research in these species is very important to fill information gaps regarding the population status and habitat aspects of the use of goldringed tanager and black-and-gold tanager endemic and endangered species of Colombia. This way you can achieve effective management plans and conservation of these species monitoring in the medium and long term and involving local communities in environmental education strategies for the protection of these species and their habitat.
