Descripción

Preliminary studies were carried out on the activity and distribution of the two species of Galapagos bat using heterodyne bat detectors. Monitoring at four sites on Santa Cruz Island from November 2003 to August 2005 revealed no evidence for seasonal migration between the highlands and lowlands for either species. Bat activity was lowest at all sites during December–March and increased over the year. The Hoary Bat Lasiurus cinereus was the commoner of the two species and showed three nightly activity peaks, as determined by all-night monitoring at one site in Santa Cruz Island over a period of three months in 2004. The Red Bat Lasiurus borealis brachyotis was common at only one site,El Cascajo village. Opportunistic monitoring throughout the archipelago over the study period confirmed thepresence of the Red Bat on Floreana and revealed both species on Fernandina Island, a new island record for both. A new hypothesis is proposed, of seasonal migration between islands within the archipelago.
