Her question set me to wondering as the playing of the "wail" tapes hadn't gotten any response; excepting, of course, red squirrels who got very nervous. Pine Siskins also seem to respond to the SSHA wail call.

First, it would be nice if you'd use your "enter" key from time-to-time,
as my mailreader presents these lines by letting them fall off the
right edge of the screen and I have to scroll to read them.

Goshawk survey protocol, at least as practiced during nesting, involves
tapes, and I do believe the same protocol is used for Coops. They're
quite territorial at this time. They aren't as responsive as, say,
northern spotted owls, according to friends who've done this, so more
birds are missed.
