MorphologyRead full entry
American woodcocks are short, plump, compact birds with very long (5.9 to 7.8 cm) bills that are specialized for feeding on earthworms. Woodcocks are mottled brown, rich buff and gray in a way that camouflages them well in woodland habitat. Their heads are large, with three dark bands across the back. Woodcocks have large brown eyes that are set far back in the skull, providing rearview binocular vision. Their wings are broad and rounded.
Male and female American woodcocks are similar in appearance, though females are generally larger than males. Female American woodcocks range from 27 to 31 cm long and can weigh 151 to 279 g. Their wingspans range from 44.6 to 50.8 cm. Males range from 25 to 28 cm long and weigh 116 to 219 g. Their wingspans range from 40.4 to 45.5 cm (Keppie and Whiting, 1994; Terres, 1980).
