Foraging habitat for G. The average weight of of 6 adults from north coast of Colombia is 9 g; average weights of Average forearm skull lengths for 4 males from Nicaragua are The same measurements for 4 females from Nicaragua are Reproductive behavior varies somewhat geographically, though most accounts indicate that G. Gestation lasts approximately 3.

Normally only single offspring, but twins have been reported. Parturition occurs with the young in the head down position. Young cling cross-wise to the mother’s ventral surface with the head just posterior to the mother’s throat.

Young have been obsereved hanging on their own at 18 days, but they are known to remain attached to their mother as late as 20 days old. Flight begins at about 25 to 28 days after birth.

Observations along the north coast of Colombia suggest that G.

Some animals defend small territories less than 10 m square around preferred food plants and will chase intruders as far as 30 m. The high pitched chattering vocalizations made during these aggresive interactions are the only sounds made by this species that are audible to humans.

Other animals have a trap-line feeding behavior. These animals visit a variety of plants each night, follow the same route each night and monitor resource availability. Most trap-line feeders have routes between and m, though some have been recorded as long as m. Foraging by both territorial and trapline feeders is concentrated in the first four hours after sunset.

Animals forage either by hovering at a flower or by hanging or sprawling on a flower. Colonies of as many as 1, individuals have been reported. Pollen, nectar, flower parts, fruit, insects. Glossophaga soricina is known to consume parts of at least 34 different species of plants and shows clear preferences locally.

This species is probably important as a pollinator of flowers and disperser of seeds of economically important woricina species. There are no indications that G. Glossophaga soricina has several morphological features that have been interpreted as adaptations for nectivory: Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities.

Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal. Biology of bats of the New World family Phyllostomidae.
