Certhia americana, Creepers, Foraging Behavior
From 20 February to 4 April 1983, 423 observations were made of foraging brown creepers (Certhia americana) in central Iowa. Diameter at breast height (DBH) of the tree used as a foraging site, time, temperature (°C), and general weather conditions were recorded during each observation. Ambient temperature was related to foraging site selection; as temperature decreased, brown creepers selected larger diameter trees more exclusively as foraging sites. As ambient temperature increased, the creepers included smaller diameter trees.
