c) A further factor that could have affected bird collisions detectability was the removal of the bird bodies by scavengers, such as coatis (Nasua narica
) and domestic cats (Felis domesticus).
Las especies de talla mediana y grande estan representadas por especies con valor comercial como el pecari de collar (Dycotyles angulatus Cope, 1889) y el venado cola blanca (Odocoileus virginianus Zimmermann, 1780), y por carnivoros como el puma (Puma concolor Linnaeus 1771), el tigrillo (Leopardus pardalis Linnaeus 1758), el coyote (Canis latrans Say 1822), la zorra gris (Urocyon cinereoargenteus Schreber 1775), el tlacuache (Didelphis virginiana Kerr, 1792), algunas especies de zorrillos (Mephitis macroura Lichtenstein 1832; Conepatus leuconotus Lichtenstein, 1832; Spilogale putorius Linnaeus, 1758) y el tejon (Nasua narica
Linnaeus, 1766) (Perez et al., 1994; Estrada Portillo, 2010).
Because the landfill is inside an area with natural vegetation, it is visited by a wide array of wild species, including mammals, such as raccoons (Procyon lotor), coaiis (Nasua narica
), gray foxes (Urocyon cinereoargenteus), and feral dogs, as well as birds including large numbers of vultures and herons (Bubulcus ibis; pers.
For population density of species that move in social groups, specifically for Nasua narica
, we considered the group to be an independent record.
Even though Nasua narica
is listed for Peru (Pacheco et al., 2009) and is listed on Appendix III of CITES, we did not include this species in the analyses because of the ambiguous evidence for its occurrence in Peru.
In the area, 53 species of mammals have been recorded of which white-tailed deer Odocoileus virginianus, white-nosed coati Nasua narica
and eastern cottontail Sylvilagus floridanus are the most abundantly occurring, whereas nine-banded armadillo is one of the most scarcely occurring (Monroy-Vilchis et al.
This study examined the play behaviour in one group of coatis (Nasua narica
) at La Selva Biological Station in Costa Rica.
