EZ answer, Jodie (in San Jose).
The recently published The
Warbler Guide (noted below in a recent article) is one fine perch to grab:
p. 116-137 features East & West Coast warbler sonograms.
An explanation to help you “read” them is also present in
this excellent new book.
I’ll share additional thoughts on other wonderful features
in this book in the next few weeks.
Meanwhile, time to go birding, so I am now a scissors,
cutting out of here (bada bum....).
