The estimated volume of food (feces and stomach contents combined) from 11 red bats, Lasiurus (borealis) brachyotis, from the Galapagos Islands consisted of 86.8% Lepidoptera and included six different prey items. The diet of three hoary bats, L. cinereus villosissimus, consisted of 76.8% Lepidoptera and contained at least eight identifiable food taxa. Two species of ectoparasites were found on both bat species, a batfly Basilia ferruginia (Nycteribiidae), and a labidocarpid mite Olabidocarpus americanus. The macronyssid mite Steatonyssus furmani was found only on L. (b.) brachyotis, whereas two myobiid mites, Acanthophthirius lasiurus and Pteracarus completus, were found only on L. cinereus. None of the parasites had recognizably diverged from their mainland counterparts.

Big brown bats (Eptesicus fuscus) were genotyped from their feces using three sets of microsatellite primers. Genotypes obtained from bat fecal DNA consistently matched the genotypes obtained from DNA extracted from wing membrane tissue of the same bat. Identical microsatellite genotypes were also obtained from multiple fecal DNA samples from the same bat. DNA obtained from feces using a modification to the DNeasy tissue kit (Qiagen) amplified from 92% (83/90) of the samples upon the first PCR. The use of fecal DNA provides opportunities for addressing ecological and behavioral questions for animals that are difficult to capture, rare, or endangered.
