Many thanks to Cynthia, Mike, and David for your observations on
towhees.
Today (October 13) there was no indication of the Eastern Towhee
female here in Norwich village where present yesterday.
The Eastern Towhee as a whole has declined sharply in numbers in the
northeastern U.S.A. in recent decades as reported by John Hagen in a
1993 article (in Auk, volume 110, pages 863-874; article obtainable
for free on line through Google searching under "towhee decline"). As
discussed by John Hagen, natural changes in vegetation have tended to
replace early successional stages with more mature woodland, and those
changes have been unfavorable for Eastern Towhees.
In recent years in the Upper Valley there have been a relatively small
number of known sites for finding Eastern Towhees in the nesting
season, and a few such sites where towhees have been regularly found
are listed in the recent second edition of the Connecticut River
Birding Trail map for the Upper Valley. Examples from the map are the
powerline area of Boston Lot in Lebanon, NH, and in the vicinity of
the overgrown orchard on the prison property along Marton Road in
Windsor, VT. In the Upper Valley in general, the species appears to
be spottily distributed as a breeder but seemingly might occur almost
anywhere during migration.
Murin and Pfeiffer in their 2002 book "Birdwatching in Vermont"
indicate that the species has been found in the state throughout the
year but is of regular occurrence only from the latter part of April
into October. They also point out that towhees are more frequently
found in the southern Vermont than in the north.
I've not found towhees during the breeding season along Tigertown Road
in Norwich,
but my time in that large area has been limited to a few hours at most.
