Culmen (beak) length and width, wing length and body mass varied significantly among six Galapagos island populations of the Yellow Warbler Dendroica petechia aureola. Culmen length and body mass were also significantly different between Galapagos and North American populations of D. petechia. Morphological differences among island populations of D. p. aureola may be related to resource variability and the presence of different bird species on different islands.
