Weather:
Another pleasant day with a mix of sun and cloud cover and a light breeze
from the NE to ENE. Temps 14-17 C. Hazy with heat shimmer early and valley
fog burning off.

Raptor Observations:
A nice day for raptor diversity, but not the big Broad-winged push we were
hoping for following almost 5k birds at Clarry Hill yesterday. Harriers
started off the day as Glen found a pair circling up over the
Lyndeboroughs, and several more passed by day's end. Ospreys picked up with
winds shifting earterly later in the day. The Broad-wings came mainly in
'cups' vs. any real kettles despite no abundant lift due to a warm
landscape and ample sunshine. Stunning looks at a close juvenile harrier,
which was followed a minute later by the season's second peregrine, taking
the same path.

Non-raptor Observations:
A couple of new arrivals included a Ruby-crowned Kinglet in partial song
and two White-throated Sparrows calling in the shrubs. Also notable were
Barred Owl, two Double-crested Cormorants, two Tennessee Warblers, and the
continuing two Eastern Towhees and one immature White-crowned Sparrow.
Ruby-throated Hummingbirds 5/68
Monarchs 21/340

Predictions:
Still waiting for another big push of Broad-wings. The big day has
historically occurred on 9/17 more frequently than on any other day in the
site's history. Wind direction seems unfavorable, but it may remain light
enough to facilitate continued migration. Either way, come on up and cheer
on the home team, and admire the newly improved view.
