Hi All,

There was a steady migration of warblers each night during the last week,
with about 100-200 calls detected per night. Magnolia Warbler slightly
surpassed American Redstart as the most common warbler species for the week.
Chestnut-sided Warblers continued to be higher than normal. Common
Yellowthroat, Black-throated Green Warbler, and Northern Parula were species
that were seen in good numbers for the first time. Cape May Warbler and
Canada Warbler continued their relatively high numbers. 

Thrush migration also began this week, led by Swainson's Thrush, as is to be
expected.

Among sparrows, there was an increase in Savannah Sparrows moving.

The sound of duck wings beating were tentatively identified as Black
Scoters. The males have a distinctive wing sound. So also the American
Woodcocks were identified by the sound of their wings.

Flycatchers rarely give their flight calls but one Alder Flycatcher obliged.
Vireos have no known night flight calls.

Rare birds for the week were Dickcissel and Indigo Bunting.

A total of 791 night flight calls were recorded.

A complete list of species detected and the number of night flight calls
