A new prey item for the snake Boiruna maculata (Serpentes: Dipsadidae) in the yungas of Bolivia

Climbing and swallowing: new food item in the diet of Boiruna sertaneja Zaher, 1996 (Squamata: Dipsadidae) with note of climbing behavior

“…trigeminus, Philodryas sp. and Xenodon merremii (Wagler, 1824); and viperids, Bothrops erythromelas Amaral, 1923 and Crotalus durissus Linnaeus, 1758 (VITT;VANGILDER, 1983;GAIARSA et al, 2013;LEITE et al, 2017;SALES et al, 2019). Here, we report the first record of predation on the Common-Racer, Philodryas nattereri (Steindachner, 1870), by B. sertaneja.…”

“…The genus Boiruna comprises two Pseudoboini species distributed in the cis-Andean region of South America: Boiruna maculata (Boulenger, 1896) and Boiruna sertaneja Zaher, 1996(GUEDES et al, 2020. Popularly known as "mussuranas" in Brazil, they are medium-to large-sized opisthoglyphous snakes, with ophiophagus habits, and commonly feed on large venomous snakes, such as those in the genera Bothrops and Crotalus (SCOTT JR. et al, 2006;QUINTEROS-MUÑOZ, 2015). Boiruna sertaneja is a large species (maximum SVL = 1940 mm), widely distributed in lowlands of northeastern Brazil where it inhabits xeric open formations, and is endemic to the Caatinga (GUEDES et al, 2014).…”

“…Although B. sertaneja is an ophiophagous specialist (ALENCAR et al, 2013), it can be opportunistic with a diet that includes small vertebrates, such as the following: the lizards Ameiva ameiva (Linnaeus, 1758), Diploglossus lessonae Perecca, 1890 and Tropidurus hispidus (Spix, 1825); rodents, such as Thrichomys apereoides Lund, 1839 and Rattus rattus Alexandrinus E. Geoffrey, 1803; and even dead items, such as Columbina picui (Temminck, 1813) (VITT; VANGILDER, 1983;GAIARSA et al, 2013;SALES et al, 2019). The following snake species have been previously documented for the B. sertaneja diet: boids, Boa constrictor Linnaeus, 1758 and Epicrates assisi Machado, 1945;colubrids, Erythrolamprus viridis (Günther,1862), Lygophis dilepis Cope, 1862, Oxyrhopus cf.…”

New elevational record for Walker’s Slender Snake, Tachymenis attenuata Walker 1945 (Squamata: Dipsadidae), with notes on taxonomy and natural history

“…Diets of Slender Snakes, medium-sized opisthoglyphs with attenuate bodies that can be active either by day or night in both terrestrial and arboreal situations, consists mainly of amphibians and lizards (Walker 1945;Giraudo et al 2012). Information about the diets of Bolivian snakes is scarce and only a few reports address prey taken by colubrids and dipsadids (Quinteros-Muñoz et al 2010;Miranda et al 2015;Quinteros-Muñoz 2015, 2021a, 2021b.…”

Contribution of camera-trapping to the knowledge of Abrocoma boliviensis

“…4) que no existan falsas detecciones, lo cual es fácilmente logrado porque las características morfológicas de A. boliviensis son particulares de la especie, lo cual hace que se la identifique correctamente. Asimismo, los modelos de ocupación, al calcular una probabilidad de detección, reducen posibles ROEDORES Y TRAMPAS CÁMARA otras localidades de Bolivia se encontraron indicios de la presencia de la especie, a través de restos obtenidos en estómagos de serpientes y fotografías (Rivero et al 2004;Quinteros-Muñoz 2015;Hidalgo-Cossio et al 2016). En los registros fotográficos, la especie es fácilmente identificable debido a sus características morfológicas, como la cola larga y peluda (Patton et al 2015;Taraborreli et al 2015); sumado a su tamaño, hocico corto y ancho, orejas grandes y redondas con una ligera muesca, patas gruesas y notorias respecto a otros roedores cricétidos (Glanz y Anderson 1990;Emmons 1999;Braun y Mares 2002).…”
