Around a dozen park visitors stopped by as well as a couple volunteers.

A weak cold front passed through overnight, the first of any significance
this fall migration season during a very hot, hazy and humid stretch of
weather the past two months. High pressure built in from southeastern
Canada giving us a NE flow that veered E then S here on the coast with the
seabreeze while providing extensive cloud cover. Semi-cooperative
conditions plus those in-between moderate winds added up to conducive
flight variables for our site. Temperatures were in the low 80s with drier
but still muggy air.

Raptor Observations:
While the raptors have not been held back by rain, most days have featured
hot and uncooperative S flow conditions. Some have undoubtedly trickled
through but clearly we are just beginning as the early moving OSPR were
built up a bit. A few local OSPR, TUVU, BAEA and RTHA were all noted. Birds
flew at varying heights, most locked in thermals or cruising out at
mid-levels. Some were at the limit of binocular range. They were spread
across the sky but following the most frequently used NE to SW corridor.
Raptors did continue and pick up in numbers despite the local and low-level
winds shifting and may have all afternoon. Obligations made us depart, not
the birds!

Non-raptor Observations:
Southbound migrants included:
Chimney Swift  107
Ruby-throated Hummingbird  11
Tree Swallow  24
Bobolink 15

Migrants in the park included:
House Wren  1
Gray Catbird  1
Common Yellowthroat  2
Yellow Warbler  1
Prairie Warbler  1
warbler sp. (Parulidae sp.)  3
Scarlet Tanager  1

Other notable birds included:

One would think it would be slow with a mostly easterly flow turning
southerly, but today was productive, and it may be again.
