The bat fauna of Lamanai, Belize: Roosts and trophic roles

Thirty-six of the 70 species of bats known from Belize were recorded from t he area around Lamanai, Orange Walk County: two in roosts and 34 in about 6 80 mist net hours that produced 560 captures. Day roosts used by 35 of the species were located using radio-tracking (Sturnira lilium, Platyrrhinus he lleri, Centurio senex and Bauerus dubiaquercus) or general searching for ro osts (Rhynchonycteris naso, Saccopteryx bilineata, Saccopteryx leptura, Dic lidurus albus, Mimon bennettii, Micronycteris schmidtorum, Carollia brevica uda, Carollia perspicillata and Eptesicus furinalis). Data on the day roost s of 23 other species were determined from the literature. Most species rep orted from Lamanai (19) roosted in hollows, while others used foliage( 6), tents (3), sheltered sites (2), crevices (2), open sites (1), and a few spe cies used more than one type of day roost (hollows and crevices (1); hollow s and foliage (1); hollows, foliage and tents (1)). The fauna consisted of 13 aerial foragers, 9 gleaners, 11 fruit/leaf caters, one trawler, one flow er-visitor and one blood-feeder. In day roost use and foraging behaviour, t he Lamanai fauna did not differ significantly from that of Paracou, French Guiana, but both these locations differed from the bat fauna of Kruger Nati onal Park, South Africa, in foraging behaviour.
