There was not much nocturnal migration the week of September 21-28 (a large
flight the night of 28-29 September will be included in next week's report).
Heavy rains appeared to bring migration to a standstill. It also became
increasingly difficult to keep microphones dry! Only 464 night flight calls
were recorded during the week with the most common bird being Savannah
Sparrow, followed by Common Yellowthroat, White-throated Sparrow, and
Black-throated Green Warbler. Rare or unusual birds this week included
Scarlet Tanager and White-crowned Sparrow. The summary of night flight calls
for the week beginning the evening of September 21 and ending the morning of
September 28 is as follows:
