Hi All,
Nocturnal migration over Carleton, Yarmouth County was considerably dampened
by the amount and frequency of rain occurring during the last four days of
the week. A total of 674 calls representing an estimated 532 minimum number
of individual birds was recorded. However, 51% of these calls occurred on
the night of September 12-13. This night started with a northeasterly
tailwind for southwest bound migrants. The wind gradually veered to the
southeast during the early morning hours. The most common bird of the week
was Magnolia Warbler with 120 calls. The second most common bird was
Swainson's Thrush with 100 calls. Common Yellowthroat (68 calls), Northern
Parula (38), Black-and-White Warbler (35), and Blackpoll Warbler (32) were
the most common warblers after Magnolia Warbler. American Redstarts declined
to only 26 calls for the week. Black-throated Blue Warblers continued to
impress and Cape May Warblers were down somewhat from the previous week.
Uncommon or rare birds for the week included Solitary Sandpiper (1
individual), Scarlet Tanager (2 individuals), White-crowned Sparrow (2
individuals), and Prairie Warbler (3 individuals). A possible Louisiana
Waterthrush was recorded at 4:02 am on September 8th. The night flight call
can be heard and its spectrogram viewed at
https://www.youtube.com/watch?v=5FJnGnxeYCw. The spectrographic
characteristics of this call (described at the previous link) were
consistent with Louisiana Waterthrush. However, there remains a possibility
that this species could be mistaken for an unusually modulated and longer
than normal Blackpoll Warbler call. Thus I have included it in the category
of unidentified warbler calls. As always, a summary table is provided below.
Formatted tables and other 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.
