Diet of the colubrid snake, Thamnodynastes strigatus (Günther, 1858) from Paraná State, Brazil, with field notes on anuran predation

São apresentados dados da dieta de Thamnodynastes strigatus (Serpentes: Colubridae), a partir da dissecção de 44 espécimes. No tubo digestivo dos exemplares examinados foram encontrados anfíbios anuros (71,4% da amostra), roedores (14,3%), peixes (10,7%) e lagartos (3,6%). A maioria das espécies de anuros (Bufo sp., Leptodactylus sp., Physalaemus cuvieri e Scinax fuscovarius) encontradas no exame de conteúdo estomacal de T. strigatus, utiliza o solo ou o nível d'água como sítio de vocalização. Também são apresentados dados sobre a observação de eventos de predação na natureza.

The diet of bats from Southeastern Brazil: the relation to echolocation and foraging behaviour

In this study the incidence of moths and beetles was examined from feces samples of bats that use different foraging behaviors. Twenty sites around the Fazenda Intervales, a Field Research Station located in São Paulo State, in southeastern Brazil were sampled. Feces were collected from bats caught in mist nets, Turtle Traps or hand nets and, in one case, from beneath a roost. Feces samples were taken from six species of bats: Micronycteris megalotis (Gray, 1842), Mimon bennettii (Gray, 1838), Furipterus horrens (F. Cuvier, 1828), Myotis riparius Handley, 1960, Myotis ruber (E. Geoffroy, 1806) and Histiotus velalus (I. Geoffroy, 1824). To record and describe the frequencies dominating bat echolocation calls, an Anabat II bat detector coupled with an Anabat ZCA interfaces and DOS laptop computers were used. The data show that Furipterus horrens feeds extensively on moths, as predicted from the features of its echolocation calls. Gleaning bats, whose echolocation calls are much less conspicuous to moths take a wide range of insect (and other) prey.
