less of the gleaning Warblers. It prefers
birches, but is found in rather open growths of other trees. Its
commoner song consists of a string of six or eight or more lively rapid
notes, running into a rolling twitter. It has also a flight-song.

The nest is placed on the ground; the eggs, which are laid in May or
early June, are white, spotted with reddish brown.

The Orange-crown is a rare fall migrant in the North Atlantic States,
but common in Florida and southern Georgia in the winter. It frequents
the upper branches of trees though, as with most members of its genus,
it nests on the ground. Its call-note is a sharp, characteristic _chip_;
its song is said to resemble that of the Chipping Sparrow.
