“…Rodents and marsupials are known to build nests in trees cavities, palms, fallen logs, and even directly on the ground (Ceballos 1990;Loretto et al 2005;Moraes and Chiarello 2005;Nowak 1999). The tail seems to play a crucial role in nest building, which certainly is an advantageous behaviour to improve body temperature control, to secure, bear and raise young, (Fadem et al 1986;Lynch and Possidente 1978).…”

a b s t r a c tWe present the first quantitative description of postural behaviour of a free ranging metatherian, the bare-tailed woolly opossum, Caluromys philander. Postural behaviour was observed using 10 camera traps set in front of artificial nests, located in the understory of an Atlantic forest site in Rio de Janeiro, Brazil. Seven locomotory and positional modes were identified, with a predominance of diagonal couplets. Individuals used three types of grasp as observed in captivity, but the frequency of digital grasping was higher in the wild. The tail was used as an additional grasping limb, preventing falls and freeing hands to other activities, but the tail was also used to carry leaves for nest building. The use of camera traps may represent a breakthrough in the study of positional behaviours in the wild.

“…An interesting point is concerning the capture of a female in February, May and June 2013; in February the female was carrying eight very young cubs and in June also eight more developed cubs (with more evident ears and eyes), but in May the female was captured without any cub. As the reproductive biology of M. nudicaudatus is considerably unknown remains unclear if the four months between February and June were enough to the full growth of a litter and the birth of another or if the M. nudicaudatus females eventually gives its offspring in the nests they build (see Loretto et al 2005) while foraging, an unusual trait among didelphids.…”

Due to the very rare mammal inventories in the northern half of the Atlantic Forest in the state of Bahia, Brazil, all initiatives to increase the knowledge of the group in this region are greatly appreciated. Thus, herein we present an inventory conducted in the privately owned Guarirú Nature Reserve, a fragment of Atlantic Forest in several conservation/regeneration stages. Sampling was carried out using Tomahawk, Sherman, and Pitfall traps over one year. The sampling resulted in 154 captures of 93 individuals from 12 different species. The didelphids Didelphis aurita, Gracilinanus micro tarsus, Marmosa murina, Marmosops incanus, Metachirus nudi caudatus, Micoureus paraguayanus, and Monodelphis americana were recorded, as well as the cricet ids Akodon cursor, Oligoryzomys sp., and Rhipidomys sp., and the echimyids Trinomys albispinus and T. setosus. Given the relative lack of knowledge about this important portion of the Atlantic Forest this inventory is an important contribution to the mammalogy of Brazil.

“…were not observed in this study, although they may be similar to those described for other didelphids. The nests described are spherical or globe-shaped (Unger 1982;Loretto et al 2005). The nests of M. domestica have three levels: the first is the base, the second is an inner chamber with thick walls, and the third forms the vaulted ceiling (Unger 1982).…”

Notes on the behavior of opossum (Didelphis sp.) in the wild in Usumacinta Canyon, México

Los tlacuaches son animales nocturnos, generalistas y oportunistas; no obstante, se conoce poco de su conducta en vida silvestre, ya que la mayoría de los estudios existentes son en cautiverio. En esta nota se reporta la conducta de Didelphis sp. en vida silvestre utilizando fotos y videos de una cámara trampa, resaltando el uso de la cola para transportar material. En el Cañón del Usumacinta, Estado de Tabasco, México, se colocó una cámara trampa el 8 de abril de 2020; se dejó funcionando y programada para tomar fotografías y videos. Se revisó el 2 de mayo del mismo año, identificando y separando los archivos correspondientes a Didelphis sp. Se identificó la conducta observada, considerando la hora y el sexo de cada individuo identificado. Se obtuvieron 209 registros de fauna silvestre, de los cuales 55 correspondieron a Didelphis sp., todos capturados durante la noche. Se identificaron 5 conductas principales dentro de las que destacan el tránsito con crías en el lomo y el transporte de material vegetal con la cola, probablemente hojas de garabato (Celtis iguanaea) para la construcción del nido. La mayoría de las conductas observadas corresponden al forrajeo; sin embargo, se reporta, por primera vez para México, el comportamiento de transportar material vegetal con la cola, presumiblemente para construir su nido. También, se reportan 3 picos de actividad durante la noche y se observa a una hembra con crías en el marsupio y posteriormente en su lomo.
