coverts tlie same ; lower part of the back, bluish white ; tail, 
formed like those of the Woodpecker genus, and often used 
in the same mariner, being thrown in to support it while 
ascending the stalks of the reed ; this habit of throwing in the 
tail it retains even in the cage ; legs, a brownish flesh colour ; 
hind heel, very long ; bill, a bluish horn colour ; eye, hazel ; 
see fig. L In the month of June this plumage gradually 
changes to a brownish yellow, like that of the female, fig. 2. 
which has the back streaked with brownish black ; whole lower 
parts, dull yellow ; bill, reddish flesh colour; legs and eyes as 
in the male. The young birds retain the dress of the female 
until the early part of the succeeding spring ; the plumage of 
the female undergoes no material change of colour.

Pennsylvania, is a bird of passage. It arrives here late in 
April ; has a loud, lively, and energetic song, which it con-
