Nice... as always, Curt!
Concerning the BaOw, Odom & Mennil, in a 2010 Condor article 112(3) p549 s=
ay in the free abstract:
" Calls of females were higher in pitch with longer terminal notes and more=
vibrato than those of males. Using these differences, cluster analysis ass=
igned owls to two groups corresponding to predicted sex with 91% accuracy."
Has anyone looked at the article and tried to use their ideas?
I know people who claim to be able to tell the sex of a BaOw when they hear=
it and I believe them because I like them lots and because they're first c=
lass naturalists. But I haven't ever been able to test their claim or get =
them to offer opinions on my recordings.
It'd sure be fun to be able to sex the callers, though!
