4.75 WS6, Short Tail often cocked, upperparts unstreaked and grayish
brown,
faint buffy eyebrow, underparts grayish white with some buffy barring
on

Behavior
Range
is at the edge of rural or suburban woods and mountain forests,
clearings
and aspen groves. Male establishes a small breeding territory by
singing
from exposed perches and putting sticks in prospective nest
holes.
When a female enters the territory, his song becomes high and squeaky
and
he vibrates his wings. After pairing the female chooses one of
his
nests, adds lining and lays 5-6 brown-marked white eggs. The male
feeds her while she incubates. They are aggressive to other
hole-nesting
species and may destroy their eggs and young. May use nest box.
Altricial,
1-2 broods, Incubation 12-15 days.
