are a little more shy than they were during the season 
of incubation, and their note is seldom heard; and, when it 
is, it consists of a melancholy strain, quite different from 
that uttered in the spring and early summer.

lower tail coverts white, or sometimes with a faint tinge of yellow; the lower 
tail coverts somewhat streaked with brown in the centre; on each side of the rump, 
generally concealed by the wings, is an elongated bunch of white silky feathers; 
the wings and tail very dark brown, the former with the edges of the secondaries 
and tertials edged with dull-white; the lower wing coverts and axillaries grayish- 
brown; the tips of the primaries and tail feathers rather paler; feet and upper 
mandible black, lower mandible brown; the young of the year similar, but the
