We studied the social organization of a colony of the fruit bat Carollia brevicauda in artificial shelter Bochalema, Northen of Santander, Colombia. Using a new type of marking and by focal sampling, one colony was observed from September 2007 to September 2008. It was determined that the social structure in the colony is integrated by four groups, which did not vary in structure over time. It was established that females were more faithful to the shelter than males. We assessed time budget day and there was that individuals have a 73.9 % time without any activity, followed by grooming with a 26.6 %, and females had higher activity than males, especially in dry season. We found that C. brevicauda has differences with records of C. perspicillata such as the fidelity of females and non-influence of lunar light over the hour of emergence from the refuge.
ORGANIZACIÓN SOCIAL DE UNA COLONIA DEL MURCIÉLAGO EN UN REFUGIO ARTIFICIAL, BOCHALEMA, NORTE DE SANTANDER, COLOMBIA
Se estudió la organización social de una colonia del murciélago frugívoro Carollia brevicauda en un refugio artificial en Bochalema, Norte de Santander, Colombia. Empleando un nuevo tipo de marcaje que consiste en decoloración capilar y mediante muestreos focales se observó la colonia desde septiembre de 2007 a septiembre de 2008. Se determinó que esta es definida por cuatro grupos los cuales no variaron en su conformación a lo largo del tiempo. Se estableció que las hembras fueron más fieles al refugio que los machos. Se evaluó el presupuesto de tiempo diurno y se registró que los individuos tienen un 73,9 % de tiempo en reposo, seguido del acicalamiento con un 26,6 % y las hembras presentaron mayor actividad que los machos sobre todo en época seca. Se determinaron diferencias en registros entre C. brevicauda y C. perspicillata , como por ejemplo la fidelidad de las hembras al refugio.
