While travelling to Yarmouth on June 3, I briefly stopped at Mavillette
Beach to look for tiger beetles.  No luck, but I did flush what first
appeared to be a Nelson's Sharp-tailed Sparrow from the marram grass on
the dunes - it landed in the grass about 10 yards away.  The orange on
the face seemed brighter than I expected, so I spished in hopes of
bringing it in sight.  A second bird promptly flushed from the same
spot, and landed with the other.  Both popped up on the grass and
watched me.  In addition to the brighter orange on the sides of their
heads, both also had dark, well-defined streaks on the undersides, and
very little in the way of buffy wash on the breast/flanks, suggesting
Saltmarsh Sharp-tailed Sparrow rather than Nelson's.  I watched for a
minute or so until they departed farther down the dune.  Unfortunately,
neither bird sang.  There were typical Nelson's songs emanating from the
salt marsh complex behind the beach.  I find this intriguing - the
northern limit of the Saltmarsh Sharp-tailed Sparrow's distribution is
approximately at the same latitude, just across the gulf in southern
Maine.

While home, I also managed to conduct point counts for the atlas in a
couple of squares.  Among the more notable records was a singing male
Willow Flycatcher at Lower Concession on June 6, in scrubby apple trees
along a field margin grading to alder swamp (Concession square).  I also
found singing Warbling Vireos at two points on June 8: near Norwood
Clearwater Lake and along the Salmon River in Harington (Hectanooga
square).  I heard another nearby on the Salmon River when I stopped to
look for a phoebe nest.  I did not find these records particularly
interesting until I later looked at the old atlas and realized there
were very little in the way of mainland NS records for Warbling Vireos.
They were in the typical habitat where one finds them reasonably regular
in central NB - riparian hardwood stands - but with the hardwoods
consisting of red maple rather than the silver maple found along most of
the lower Saint John River.  I suspect that they may be overlooked
(underheard?) to some extent in southwestern NS.
