| description | Social correlates of reproductive events of a colony of Anoura geoffroyi from the La Mina cave at San Francisco de las Tablas, State of Mexico, 2670 m, were studied for two years during which the bats showed consistent seasonal breeding pattern, as well as colony rearrangements. Females are monoestrous and monotocous. Mating took place in the summer (June-July) when males reach maximum testes size and females were in estrus. Births occurred from late September to mid November. Lactation began in late September and extended until early January. Both gestation and lactation lasted three months. Females underwent the reproductive events in two sequential groups. In the spring (March-May), the colony was organized into 10-12 groups of 13-15 individuals, containing females, males and young. In the summer (June- August), the groups were reduced to seven or eight, each containing 25-30 individuals. Later, 80% of the population formed one group, the mating colony. In September, the group was made up of 150 individuals, most of them pregnant females. In October, males left the colony, and a maternity colony was formed, which broke up in January, with the return of the males. When nursing females foraged, they left their offspring in the colony in care of a small number of presumably adult females which roosted in the center of the nursery group. Female-male ratio fluctuated from 1:1 to 1.5:1 during most of the year, except in October (3:1), November (8:1), and December (16:0) when departure of the males and the formation of the maternity colony took place. |

Durante dos años se estudiaron los eventos de la reproducción y su relación con la organización social y la conducta en una colonia de Anoura geoffroyi localizada en la cueva La Mina, San Francisco de las Tablas, Estado de México, 2,670 m. Durante los dos años, los murciélagos mostraron el mismo patrón estacional reproductivo, así como los mismos rearreglos espaciales de la colonia en su refugio. La cópula se efectuó en verano (Junio-Julio) cuando los testículos de los machos alcanzaron su mayor talla y las hembras estaban en estro. Los primeros nacimientos sucedieron a finales de septiembre y los últimos a mediados de noviembre, siendo las hembras monoéstricas y monotocas. La lactancia se inició a fines de septiembre y se prolongó hasta principios de enero. La gestación y la lactancia duraron alrededor de tres meses cada una en la colonia. Las hembras llevaron a cabo los eventos reproductivos en dos grupos secuenciales. En primavera (marzo-mayo) la colonia se organizó en 10 ó 12 grupos de 13 a 15 individuos entre hembras, machos y juveniles. En el verano (junio-agosto) los grupos se redujeron a siete u ocho, pero cada uno constaba de 25 a 30 organismos. Más tarde, el 80% de la población se conglomeró en la colonia de reproducción. En septiembre el grupo constaba de 150 individuos, en su mayoría hembras preñadas. En octubre los machos se fueron y se formó una colonia de maternidad que se rompió en enero con el regreso de los machos. Cuando las hembras salían de la cueva en busca de alimento, dejaban a sus hijos en la colonia al cuidado de un número reducido de individuos, presumiblemente hembras adultas. Los críos al nacimiento estaban desnudos y eran de color rosado. La proporción de sexos fluctuó entre 1:1 y 1.5:1 hembras por machos durante la mayor parte del año, excepto en octubre (3:1), noviembre (8:1)y diciembre (16:0) cuando los machos partieron y se formó la colonia de maternidad.
