Visitors today were Sue Southon and Cary Graham.

We had very light winds from the N / NE, picking up very lightly towards
noon, with temperature at 22 C for an 8:30 start, rising to 28 by the end
of the watch, feeling more like 34.  Sky was hazy again, and although there
actually was very little cloud cover, visibility was only 6 to 10 km.  

Raptor Observations:
Despite weather conditions definitely not conducive to raptor flight, we
counted a total of 22 birds today from 4 species: Osprey (2), Northern
Harrier (3). Sharp-shinned Hawk (2) and American Kestrel (15).  
Local raptor species seen today included the usual Bald Eagles (3), a lone
Turkey Vulture and another Osprey which was fishing along the cliff and out
over the lake during the last hour.

Non-raptor Observations:
Thanks to visitors and regulars for their contributions to today’s
non-raptor list.  Today’s highlights were 3 New Species for this season
which were Belted Kingfisher, Carolina Wren, and Northern Waterthrush. 
Other Warbler species seen were Yellow, Magnolia, Black-throated Blue,
Blackburnian, Black & White, Am. Redstart, Tennessee, Nashville, and
Wilson’s for a total of 10 species.  In addition, we had 3 Vireo species
today including Warbling, Red-eyed and Philadelphia.  A couple of other
highlights were an Orchard Oriole spotted across from the knoll by Jim,
Wood Thrush and Ruby-throated Hummingbirds which are now being seen zipping
across the field as well as in flower patches, in the woods, etc.  These
are only highlights out of our total of 45 passerine species today.
One American Snout was still present in front of the knoll; other butterfly
highlights were Tiger and Black Swallowtails and the Monarchs, a daily
Lots of Black Saddlebags, Green Darners and 12-spotted Skimmers
(dragonflies) are being seen daily in the field.  

With probable thunderstorms moving through tonight, the wind will shift to
NE and then E by tomorrow, around 15 km / hr.  This is a slightly better
forecast for raptor migration as northerly flow is needed to push raptors
towards the lake, but the temperatures will remain very high with high
humidex values throughout tomorrow and the weekend.
