“…For each snake, we recorded weight (± 1 g), stomach contents, the habitat in which it was first observed, and if fleeing, the cover it chose. The taxa in stomach contents were examined after stripping the snakes (Carpenter 1952). Habitat categories were divided into organic (tree base, debris heap, log or board, tree, shrub) and inorganic (rock slope, bedrock or talus, water, rocks) components.…”

“…Desta forma, a escolha de hábitat por esses animais poderia ser tão somente um reflexo da escolha de hábitat de suas presas (Carpenter, 1952;Gregory, 1984;Shine & Lambeck, 1985) que, em Bothrops adultas, são representadas predominantemente por roedores (Hoge, 1952;Sazima, 1992;Gasparini et al, 1996). Doze espécies de roedores são citadas para mata de galeria do bioma Cerrado do Planalto Central (Mares et al, 1989).…”

“…Mesmo assim, a segregação de hábitat em serpentes tem sido documentada (Shine, 1977;Reinert, 1984), embora outros estudos demonstrem que essa segregação não se estende, necessariamente, a todas as espécies (Carpenter, 1952;Pough, 1966;Hebrard & Mushinsky, 1978).…”

Habitat selection by two lancehead species (Bothrops moojeniHoge and B. neuwiedi Wagler) (Serpentes, Viperidae)Our data regarding the use of the habitat by Bothrops moojeni and B. neuwiedi (Serpentes, Viperidae) was obtained from information related to specimens donated to the Jardim Zoológico de Brasília, Universidade de Brasília, Jardim Botânico do Distrito Federal, and also from a half-captivity experiment. The results show a strong segregation of habitat between both species, with B. neuwiedi largely restricted to open areas, and B. moojeni using mainly the forest and ecotones. There is no significant difference in habitat selection between the individuals maintained isolated and those confined to the same yard. Therefore, one species aparently does not interfere directly in the habitat selection of the other.Key words: Serpentes, Viperidae, Bothrops, Lancehead, habitat selection, cerrado, half-captivity. RESUMOForam utilizados dados relativos ao uso de hábitat por espécimes de Bothrops moojeni e B. neuwiedi (Serpentes, Viperidae) provenientes de doações ao Jardim Zoológico de Brasília, Universidade de Brasília, Jardim Botânico do Distrito Federal e de um experimento de semicativeiro. Os resultados indicaram forte segregação de hábitat entre ambas as espécies, sendo B. neuwiedi amplamente restrita a áreas abertas, enquanto B. moojeni utiliza principalmente a mata e o ecótono. Não foi encontrada diferença significativa na seleção de hábitat entre indivíduos mantidos isolados e aqueles confinados em um mesmo cercado. Assim, aparentemente, uma espécie não interfere diretamente na seleção de hábitat da outra.

“…Diet often depends not only on the prey preference of the species, but also on the availability of prey, which changes with space, time, and ontogeny (Carpenter 1952). If the preferred prey is less available, then diet may consist of a less preferred but more available prey item (Gregory and Nelson 1991).…”

“…When the prevalence of prey species is averaged across studies, Common Gartersnakes show a strong preference for frogs, followed closely by earthworms, while salamanders, fish, and mammals occur in their diet less frequently, and all other prey items can be considered rare ( Table 2). Studies of prey preference demonstrate that Common Gartersnakes almost exclusively eat earthworms when they are small and incorporate larger food items, such as amphibians, into their diet as they grow larger (Carpenter 1952;Gregory 1978;Halloy and Burghardt 1990;Gregory and Nelson 1991), a practice that is likely related to gape-size limitation (Halloy and Burghardt 1990;Rodriguez-Robles et al 1999).…”

Evidence of Predation on Nestling Birds by Eastern Gartersnakes (<i>Thamnophis sirtalis sirtalis</i>)

Diet is an important aspect of the natural history of all animals, but diet can vary through space and time because of variations in prey availability. The diet of the Common Gartersnake (Thamnophis sirtalis) consists mainly of earthworms and frogs, but other prey items might be important when they are locally abundant. I report an observation of a female Eastern Gartersnake (Thamnophis sirtalis sirtalis) regurgitating 2 nestling birds in Ottawa, Ontario, Canada. Birds are seldom present in the diet of the Common Gartersnake. This rare food choice highlights the opportunistic nature of foraging by adult Common Gartersnakes and, further, demonstrates that diet depends not only on prey preference, but also on prey availability.
