A ton of visitors today...too many to note here. I do want to thank
everyone who helped with spotting birds and recording today's count...it
would've been a tough day without all the eyes keeping a lookout!  :)

The day started out with intermittent light showers all the way from Lake
Huron almost down to Hawk Cliff itself...but skies cleared fairly quickly
from the west and soon (as so often happens) we were wishing for cloud to
come back!. Eventually, some nice cumulus built back in.

The winds were very light to start then picked up a bit from the NW. The
air dried quickly and buteos and TVs were up within the next hour.  It
would appear that ground-level winds were still lighter than what the birds
were experiencing at flight levels (approx. 300-500m) since several of the
Broadwing streams were being pushed right out over the lake and were having
to angle back inland.  Temps were initially cooler to start at 10C then
climbing to 20C (though it felt much warmer in the direct sunlight). 

Raptor Observations:
After a rough start it turned into a great hawkwatching day today.  Our
total birds were 1904 with an excellent flight of Broadwings (1447)...just
a hint of what should be the main push by the end of this week. At one
point the birds were all over the sky and at several different flight
levels which made counting them challenging! There were also good flights
of Sharpies (278), Kestrels (101) and of Bald Eagles (32)....at one point
there were 6 Bald Eagles circling together...with another 4 not far
away...also Osprey (6) and N. Harrier (27) including the last 3 birds of
the day hunting together low over the bean field in front of the
observation knoll...a few Merlin and a lone adult Peregrine that sped past
just north of the counters.

Non-raptor Observations:
A lot of the usual species that've been reported over the past week,,,,only
8 species of warler including Mourning and Wilson's...a nice overflight of
3 Great Blue Herons right over the knoll and continued flights of Am.
Goldfinch.  Ther seemed to e a movement of Swainson's Thrushes with 4
reported in and around the hawkwatch along with a single (and early) Hermit
Thrush...a couple of Barn and Cliff Swallows...3 Chimney Swifts...a few
Blue-Gray Gnatcatchers and a Baltimore Oriole.  

Not as many Monarchs today...other species included Viceroy, Fiery Skipper
with fresh looking Painted Lady and Red Admiral...and a couple of Black

Looks great for Monday...predicted NW and N winds.
