Visitors:
181. Lots of visitors enjoying the holiday weekend, with many curious about
the hawkwatch. Hello again to Silas.


Weather:
Patchy fog during the morning followed by one short drizzle, and then
plenty of sunshine for the afternoon. Temperature was a chilly 50 degrees
in the morning but it reached 57 degrees by late afternoon. Light north
wind, becoming stronger in the afternoon and occasionally shifting to the
northwest.

Raptor Observations:
Excellent migration day for this early in the season! In fact, today was
the biggest day for the first week of September in the history of the
regular count. Steady flow of sharpies and broad-wings (including a few
kettles), with a diversity of other raptor species mixed in. Birds
continued to fly late in the day, so we counted a half hour longer than
usual.

Fun behavior observations included a Merlin checking out Gina, another
Merlin catching and releasing a Monarch, and a raven and sharpie playfully
diving on one another.

Non-raptor Observations:
Two male Black-throated Blue Warblers perched together on the same branch,
posing for pictures. Other highlights included a couple Chimney Swifts
flying through, a Black-and-white Warbler playing hide and seek in the
undergrowth, and several hummingbirds zipping by.

Ruby-throated Hummingbirds: 8/36
Monarchs: 31/139

Predictions:
Looks like a good day tomorrow: warm and sunny with a nice northwest wind.
