nape. Males have gray-blue wings and rufous cap,
back and tail.

Merlin
male
(detail)

by Brown and Amadon
McGraw-Hill, New York.
The facial pattern
of this 12 inch bird is less striking than that of
the American Kestrel; the mustache is poorly
defined. The underside striations appear as
stripes, and the dark tail has light bars. Males
have slate blue-gray back and wings. Females and
juveniles are like males but dark brown
above.
Stanford Note. In
winter, a male is often found atop a redwood on
Amherst Avenue just off Stanford Avenue. So
reliable is its annual return, that Kendric Smith
has produced a web page documenting its
stay:
