Six visitors and all pro observers.

A weakened high, with a reduced pressure gradient, stayed parked near
Delmarva providing light NW winds that actually turned SW/W at the end of
the afternoon. An occasional gust to 4-7MPH really helped momentarily it
seemed, and when winds went near calm it was slow. The dry air warmed to
the mid 70s under completely clear and deep blue skies. Every hour had 0%
cloud cover.

Raptor Observations:
It was a difficult day considering the positive conditions, the date and
the lack of clouds. One would have hoped we would have far more raptors,
especially BWHA, but they seem to be bottled up more N sections of New
England still, or further W. Perhaps the heat of the past few weeks delayed
things more than we anticipated. The same general themes continued with
many OSPR and similar breakdowns for other species. Those OSPR are
single-handedly saving the season so far. Birds were often very high and
very far. The BWHA we did have were all streaming, and one group of seven
was the maximum.

Non-raptor Observations:
Again, where were the diurnal passerine migrants in these conducive
conditions? They cannot be as backed up as the raptors and these counts are

Southbound migrants included:
Chimney Swift  6
Ruby-throated Hummingbird  7
Tree Swallow  11

Migrants in the park included:
Northern Flicker  2
House Wren  1

Six Monarch migrants plus an American Lady and a Viceroy. Thousands of
Common Green Darner and hundreds of Black Saddlebags filled the sky all
afternoon. There were a couple dozen Wandering Gliders, at least two
Carolina Saddlebags, and one Twelve-spotted Skimmer.

The wind will continue being very light and variable, likely shifting to a
S flow in the afternoon. The birds may be in the vicinity now but the winds
and zero cloud cover will not help, and they may not move far.
