Genus Saguinus is widely noted as “preferring” or “thriving” in edge habitats (Hershkovitz, 1977. Garber, 1980. Porter, 2001.). Data collected over a two month period in a lowland secondary forest in the interior of Suriname supports this hypothesis. These data also demonstrate regular, daily troop movements from the edge in the early morning, towards sites deeper in the interior for the bulk of the day. These regular movements reflect a preference for sleeping sites located in the edge, coupled with a preference for interior forest for feeding. Possible explanations for this behavior include (but are not limited to), an increase in foliage cover as protection from diurnal predators (primarily various raptor species), foliage cover used as relief from excessive temperatures, or an increased density of food resources. Further study at this site would likely provide clearer motivations for daily patterns of habitat use, and an extended period of study would be required to record whether these patterns hold through the change of seasons, or vary due to the seasonal shifts in weather patterns, as well as the possible seasonality of preferred food resources.
