Downy Woodpecker
Dryobates pubescens
Adult downy woodpeckers are the smallest of North America's woodpeckers, but there are many smaller species elsewhere, especially the piculets. The total length of the species ranges from 14 to 18 cm (5.5 to 7.1 in) and the wingspan from 25 to 31 cm (9.8 to 12.2 in). Body mass ranges from 20 to 33 g (0.71 to 1.16 oz). Standard measurements are as follows: the wing chord is 8.5–10 cm (3.3–3.9 in), the tail is 4–6 cm (1.6–2.4 in), the bill is 1–1.8 cm (0.39–0.71 in) and the tarsus is 1.1–1.7 cm (0.43–0.67 in). Voice: The downy woodpecker gives a number of vocalizations, including a short pik call. The rattle-call is a short burst that sounds similar to a bouncing ball, while that of the hairy woodpecker is a shorter burst of the same amplitude. Like other woodpeckers, it also produces a drumming sound (sounds like four taps ) with its beak as it pecks into trees.

Ladder-backed Woodpecker
Dryobates scalaris
The ladder-backed woodpecker is a small woodpecker about 16.5 to 19 cm (6½ to 7½ inches) in length. It is primarily colored black and white, with a barred pattern on its back and wings resembling the rungs of a ladder. Its rump is speckled with black, as are its cream-colored underparts on the breast and flanks. Southern populations have duskier buff breasts and distinctly smaller bills. Adult males have a red crown patch that is smaller in immatures and lacking in adult females.
