This has both the "whinny" and "monotone trill" calls. These are the primary calls of the Eastern Screech. The "whinny" is often associated with nesting birds and the trill with winter birds.
FIELD NOTES
and Range Map
Eastern Screech-Owl -
Megascops (Otus) asio
Separation
in the field, of the Screech-Owls, is actually only feasible by voice. The Eastern
Screech-Owl can be distinguished with its primary
"bouncing" (mating) call or "whinny" (regular) call. This is a common owl in the
east.
The sexes are alike in appearance although male and female can be distinguished
by voice. Although visual distinctions are not conclusive to identification with
the screech-owls, the Eastern Screech tend to have slightly longer ear
tufts than the Western Screech-Owls and never a black bill. Eastern
Screech-Owls are believed to be sedentary and there is no evidence of
any migratory (or winter) movements. Eastern Screech-Owls have both gray
and brown phase birds. The bill is a pale grayish green to greenish blue
and its eyes (iris) yellow. Length is 8 1/2" (about the size of a Red-winged Blackbird). A
nocturnal owl.
