Hi,
I ventured out to Bayside Sunday morning to join the Big Sitters. We had a
fairly good and varied flight of warblers, sparrows, kinglets, and
blackbirds. When the morning flight culminated around 11am I decided to
put my boots on and wander out into the saltmarshes in the cove north of
the Bayside campground. That turned out to be a very smart choice as I
found most of the species listed by Matt H. as missing on the Big Sit
list:

Great Egret: 40+
Snowy Egret: 2
Tricolored Heron: 3 juvies
Little Blue Heron: 1 ad. + 1 juv.
