Anoura geoffroyi is a nectar bat distributed throughout the Neotropics from Mexico to Brazil (Ortega & Alarcon-D, 2008). It is particularly abundant in mid-elevation cloud forests, and reaches higher elevations than any other nectar bat (>3500m, in the Andes of South America; Muchhala, pers. obs.) . It feeds primarily on pollen and nectar from flowers, supplementing this diet with insects and, less frequently, fruit (Álvarez & González 1970; Muchhala & Jarrín 2002; Zortéa 2003). Like other nectar bats of the subfamily Glossophaginae, it possesses adaptations to nectarivory such as an elongated snout, a highly extensible tongue, and the ability to hover during flower visits (Winter & Helversen 2003; Fleming & Muchhala 2008).
