_Nesting._--Mr. Howell (1932) says that, in Florida, “the nest of the downy is usually dug in a decaying limb of a tree or occasionally in a fence post, and may be anywhere from 5 to 50 feet above the ground.” Harold H. Bailey (1925) says that “for the nesting site, they usually select a dead stub of some live tree, preferring a hard one to a soft or decayed wood. The cavity is drilled each year anew by the birds, the hole being about one and a quarter inches in diameter and eight to twelve inches deep, varying in height from twenty to sixty feet above ground.” John Helton, Jr., tells me of a nest he found on April 20, near Troy, Ala., that “was drilled in a rotten oak limb, which had fallen, been caught, and was suspended among the branches of a pine. It contained three small young and one infertile egg. The mother bird fed the young with great regularity every three minutes.” M. G. Vaiden, of Rosedale, Miss., writes to me of a nest 35 feet up in a dead snag of a pecan tree; the limb was four inches in diameter and the cavity only five inches deep. George Finlay Simmons (1925) says that, in Texas, it nests “10 to 20 feet from ground in small dead deciduous trees, or in old stumps or telegraph poles.” _Eggs._--The eggs are like those of the northern downy but slightly smaller. The measurements of 25 eggs average 19.43 by 15.24 millimeters; the eggs showing the four extremes measure =20.8= by 14.9, 20.6 by =16.7=, and =17.78= by =13.46= millimeters. _Behavior._--Writing of the habits of these woodpeckers in the sandhills of North Carolina, Milton P. Skinner (1928) says: They are seen at times with Chickadees, red-cockaded woodpeckers, Brownheaded Nuthatches, Kinglets and Juncos. And these associations seem to be actual and usual, and not temporary and accidental ones as they are between most birds of different species. The downy woodpeckers are peaceable little fellows but other birds will impose on them. I have seen a yellow-bellied sapsucker and a mob of three or four English Sparrows near Pine Bluff chasing one about. But downy was a fast flier and outflew all his tormentors each time. Their flight is undulating and typical of the woodpecker family. These woodpeckers have one trait of the Brown Creepers--they prefer to work _up_ a tree and fly _down_ to the base of the next one.
