Hi All,

The heavy rains during much of the past week greatly suppressed the volume
of nocturnal migration over Carleton, Yarmouth County. When the skies
cleared during the last two nights of the week, there was a definite push of
migrants but they were primarily late warblers with relatively few sparrows.
Sparrows still only accounted for 27% of night flight calls this week, up
from 24% last week. Overall, it was the slowest migration week this year
with a total of only 327 calls representing an estimated minimum number of
267 individuals. The most numerous calls were those of the Common
Yellowthroat with 52 calls. Yellow-rumped Warbler was the second most common
bird (46 calls), followed by Blackpoll Warbler (38 calls). The most common
sparrow call was that of the Lincoln's/Swamp Sparrow complex (30 calls).
Most likely all or largely Swamp Sparrows, it is unusual for this species to
outnumber White-throated and Savannah Sparrows. The less common or rare
birds of the week included a Pine Warbler and an Indigo Bunting. A summary
is included below, and additional information can be found at:

Estimation methods for minimum individuals

Warblers and Sparrows: Number of calls of the same taxon that have an
interval of at least 60 seconds between them.

Thrushes: The number of calls of the same species during a 60 second period
divided by 3 and rounded up to the nearest whole number.
