hello everyone,

I stumbled across a delightful video created by the Cornell Lab of O that
discusses the meaning in some of the sounds produced by crows and ravens --
and you also learn how to distinguish these two species based on their
voices alone:

needless to say, i plan to feature more Lab of O videos on "caturday" in
the future.

happy birding
