242 PICUS PUBESCENS. 



PICTJS PUBESCENS. 



Downy Woodpecker. 

 Pious pubescent LINN., Syst. Nat., I; 1766, 15. 



DESCRIPTION. 



SP. CH. Form, not robust. Size, small. Sternum, not very stout. Tongue, rather thin and horny at the tip which 

 is provided with barbs for one third of the terminal length. The extensible sheath occupies about one half of the length of 

 the tongue. Terminal hook of scapula, angled above and below. 



COLOU. Adult male. Glossy black above, including sides of head and the line extending down on to the sides, with 

 the bristly feathers at base of bill, line extending from just in front of eye, inclosing it, and reaching occiput, line from the 

 base of bill, running downsides of neck, broad line along middleof back, spots on outer webs of wing feathers, all hut ba- 

 sal portion of three outer tail feathers, and tips of next pair, white; but the white of the tail is more or less barred with 

 black. Crescent-shaped mark on the occiput, scarlet. Under portion, including under wing and tail coverts, yellowish- 

 white. 



Adult female. Similar to the male, but lacks the scarlet on the head which is replaced by white, and the whi te on the 

 tail is not as extended. 



Young. There is a decidedly sulphury tinge to the white markings, and the inner white tail feathers are almost en- 

 tirely black, in both sexes and, in the male, the scarlet patch on the occiput is more restricted; otherwise similar to the 

 adult. 



Next/ing male. Very much tinged on the white with sulphury, the forehead is black, occasionally spotted with white, 

 and the top of the head is covered with scarlet, but there is a white line. crossing the occiput. 



Nestling female. Similar to the male, but usually has the forehead spjtted with white and the top of the bead is 

 black. A specimen before me, an undoubted female of my own dissecting, has the feathers on the top of the head slightly 

 tipped with scarlet. Iris, reddish-brown, bill, blaak, bluish at base of lower mandible, and feet, bulsh, in all stages. 



OBSERVATIONS. 



As in the preceding species, specimens from the South, although smaller in size, do not differ strickingly in color, for 

 there is considerable variation in this respect in birds from all sections. The nestling plumage is worn but a short time, es- 

 peciall}' the scarlet on the head which is soon replaced by the normal color. The Hairy and Downy Woodpeckers may be 

 distinguished from all others which occur within our limits by the broad white line down the back. The Downy may be 

 known from the Hairy, not only by the smaller size, but also by the banded white on the tail. Distributed, as a constant 

 resident, throughout North America,

HABITS. 



I have said, or rather intimated, elsewhere that the Woodpeckers, as a cla?s, were 

 endowed with a superabundance of energy but there are none among them all which dis- 

 play such an amount of nervous activity as the little Downy. Always busy; now climb- 

 spirally up the huge bole of some old elm, pausing a second to give a quick tap on the 

 bark; then, as the peculiar sound informs them that the wood is solid, they will utter their
