We had a fairly good crowd today, including Joan, who saw her first Golden

We warmed up fast today, though when the wind shifted to blow cold air at
us from over the lake (at about the time the sun dipped behind the trees
behind us!), it was a bit cold. Barometric pressure dropped steadily after
8, and visibility decreased in the afternoon due to haze. 

Raptor Observations:
The highlight of our day was probably the 'lowlight' of the day of three
Great Blue Herons who were startled by a very low flying Golden Eagle. As
the big raptor soared to the west of us, flashing its white wing patches,
our local Cooper's Hawk flew very low over the water directly at us, adding
to the afternoon excitement. We also spotted a distant 'grey ghost' (which
is an adult, male Northern Harrier), and a Merlin harassing a migrating
Sharp-shinned Hawk right in front of us. 

Non-raptor Observations:
At least 450 Red-winged Blackbirds bounded/flapped above the count site, as
did over 300 Blue Jays (but they don't bound). A couple more American Crows
were spotted today, and will likely be seen in great numbers relatively
soon. Rusty Blackbirds and Common Grackles were present. Eight Monarchs
were counted today.

It will likely rain throughout the day tomorrow, which might impede
migration. The dropping barometric pressure today may have indicated to the
birds what is coming, as we counted relatively few birds.
