“…Coatis (weight=5-6 kg) and capuchins (weight=2.5-3.5 kg) are diurnal, social animals (Kaufmann 1962;Kaufmann et al 1976;Freese 1978;Rose 1997). Coati males are usually solitary, whereas females and males less than 2 years old live in groups (Kaufmann et al 1976;Timm et al 1989). Capuchins live in groups of up to 30 (Freese 1978;Baldwin and Baldwin 1977).…”

I studied the role of visibility on the vigilance behavior of coatis Nasua narica and white-faced capuchins Cebus capucinus in a dry tropical forest in Costa Rica. Vigilance and drinking behavior were observed at a waterhole where the water surface was 2-3 m below ground level for 5 days. Then I provided an artificial water pan of similar size adjacent to the natural waterhole, but level with the ground, and observed the same behaviors. Animals drinking at the natural waterhole had to descend below ground where they could not see above ground, while those drinking from the experimental pan could see approaching predators. Variations in drinking and vigilance behavior were accounted for by site (natural vs. experimental water source) and group size, with site contributing most significantly to variations. Both coatis and capuchins decreased their time to wait at the forest edge before emerging to drink, had more drinking bouts, had longer bout lengths, and decreased their vigilance behavior when they drank at the ground-level waterhole compared to the one below the surface, where their visibility was obscured. For both species, total drinking time increased, and vigilance decreased, with group size. This study demonstrated experimentally that visibility and group size influence drinking and vigilance behaviors.

“…Small frugivorous bats, especially Artibeus watsoni are very common at La Selva Biological Station (Timm 1994), thus making them reliable pollinators, whereas the only with certainty occurring mouse opossum species in the study area, Marmosa mexicana, is much less frequently observed. However, regurgitated pellets of spectacled owls (Pulsatrix perspicillata) show that they are a frequent prey at La Selva, suggesting them to be more common than they appear (Timm et al 1989). Cunningham (1995) revised hundreds of inflorescences for flower remains that permitted identification of the visitors.…”

Distributed from eastern and southern Mexico to western Panama, M. mexicana inhabits dry deciduous to highland evergreen forests, second growth and grassland from sea level to 1800 m (Alonso-Mejı´a and Medellı´n 1992; Timm et al 1989;Reid 1997;Wainwright 2002).…”

“…Due to their size and black eye mask we recognized the animals as Mouse opossums. Upon further analysis we identified the visitors as Mexican mouse opossums (Marmosa mexicana, Merriam 1897), considering the uniformly colored tail and a sparsely furred base of the tail, which distinguishes this species from the potentially co-occurring Micoureus alstoni (Timm et al 1989;Reid 1997). Based on our video recordings, our initial identification of the species was later confirmed by R.M.…”

In a study of the bat community in the marshes of l'Anse de Sinnamary, French Guiana, two hundred and twenty seven bats from twenty six species were captured, 90 % of the individuals and 85 % of the species belonging to the Phyllostomidae. Compared to a nearby forest bat community sampled using the same capture methodology, the marshes community had proportionally less frugivorous-nectarivorous species (35 % vs. 56 %) and individuals (55 % vs. 83 %) and more insectivorous-carnivorous species (65 % vs. 44 %) and individuals (45 % vs. 17 %). Species richness and diversity were the same at the two locations, whereas bat abundance was three times higher in the marshes.This work gave new insights about bat species distribution in French Guiana. Two species, Vampyrodes caraccioli and Tonatia carrikeri, were captured for the first time and could be associated with marshes and swampy areas within this region. Four more species regularly caught in marshes are very scarce or absent in forested areas elsewhere in French Guiana where closely related or sibling species are common. We comment the existence in French Guiana of five pairs of allopatric very closely related species belonging to the Phyllostomidae, one inhabiting the rain forest, the other inhabiting savannas and mesic habitat of the coastal area.Resume. -Lors d'une etude de la communaute de chauve-souris des marais de l'Anse de Sinnamary, Guyane fran9aise, 227 individus appartenant ä 26 especes ont e*te captures, parmi lesquels 90 % des individus et 85 % des espdces appartenaient ä la famille des Phyllostomidae. Compare au peuplement d'une for£t proche echantillonnee selon le m£me protocole, le peuplement des marais se caracterise par une plus faible proportion d'especes (35 % vs. 56 %) et d'individus (55 % vs. 83 %) frugivores-nectarivores, compenses par plus d'especes (65 % vs. 44 %) et d'individus (45 % vs. 17 %) insectivores-carnivores. La richesse specifique et la diversite sont similaires dans les deux sites, mais 1'abondance en individus s'est revelee trois fois suporieure dans les marais.Ce travail apporte des elements nouveaux sur la distribution des chauve-souris en Guyane fransaise. Deux especes, Vampyrodes caraccioli et Tonatia carrikeri, ont ete captures pour la premiere fois, et pourraient £tre associees ä ces zones humides littorales. Quatre autres esp&ces capturees regulierement dans ces marais sont tres rares ou absentes des zones forestieres de Mammalia, t. 59, n° 4,1995 :527-535.
