TUe Singing of Birds, B.P.Bicknell. 
Junco hiemalis. Slate-colored Junco. 
/# 
Early March is most often the time when we first hear the 
song of this Sparrow; but, according to the character of the 
season, the beginning of singing may vary within two weeks in 
either direction from the average time. After the. early days of 
April, singing is not commonly heard, and in some years it 
ceases before the end of March. April 17 is my latest record, 
although the species often remains into May. The Junco 
has two very different songs : a simple trill, somewhat similar 
to that of the Chipping Sparrow ; and a faint whispering warble, 
usually much broken but not without sweetness, and sometimes 
continuing intermittently for many minutes. It seems to slip very 
readily from a simple chirping, and is always the song with 
which the. species begins the season. Later, the first mentioned 
becomes the more general if not the only song, as I found it to be 
in the Catskill Mountains in summer, when the birds were 
breeding. 
The Snowbird does not often sing in the autumn, but I 
have heard both of its songs in October and November; and it 
seems always ready with a few feeble song-notes for any day 
that comes out sunshiny and mild in sudden change from harder 
weather.
