Hi John,

"and Indigo Bunting (probable) with 4 calls within a few seconds of each
other."

How far apart, in time, do the calls have to be before you count them as,
in this case, four birds, instead of one (calling repeatedly)? Thanks for
these reports...I wonder if we have a secret enclave of breeding Indigos up
here!

Randy
