        Forgive the untimely addition to a two-week old thread.
        My life and still only Brewster's Warbler was in the exact same
location as Steve Sanford's.  This was circa 1978, on a MOS trip with
few participants, but including Bob Ringler, maybe Rick Blom, and Pete
Webb as I remember.  Could it have been Bob's May 28 Brewster's staked
out?
        And is there some sort of nest fidelity operating here, over
four or five generations of two species (I understand that Brewster's
like the one described by Steve are first-generation crosses), or is the
area simply good for Blue-wingeds, so that repeat occurrences of
Brewster's are coincidental but not improbable?
