Distribution of rufous-and-white wrens in Central America and location of the study site. (a) Appearance and year-round distribution (orange) of rufous-and-white wrens in Central America, which also includes parts of Colombia and Venezuela not shown here (species distribution data from [19]). (b) The study site in Sector Santa Rosa of the Area de Conservación Guanacaste in northwestern Costa Rica (10°52′N, 85°36′W). The study site encompassed an area of 125 ha from 2003 to 2005 (yellow), which was expanded by approximately 115 ha (red) in 2006. The background satellite image in (b) was taken at the end of the dry season in May 2013, highlighting the limited availability and patchiness of evergreen forest in comparison to seasonal scrub forest.
