We report the first nesting record of the Central American population of Brown Creeper (Certhia americana) in the La Montañona pine-oak (Pinus-Quercus) forest of Chalatenango Department, northern El Salvador. The nest was in a cavity in the trunk of a pine (Pinus oocarpa) tree. Most insectivorous birds in this region breed during the rainy season when insects are generally most abundant; however, nesting of the Brown Creeper occurred at the height of the dry season, during January and February.
