Hi All,
Nocturnal migration was strong during the first week of September at
Carleton, Yarmouth County. A total of 1,435 night flight calls comprising a
minimum estimated number of 1,079 birds were recorded during the seven day
period. The peak night of the week and for the year so far was the night of
September 1 to the morning of September 2 when 470 flight calls were
recorded. Family composition of the flight calls during the week was 77%
warblers of 23 species, 19% thrushes of 3 species, and 2% sparrows of 4
species. American Redstart (180 calls) lost its status this week as the most
common species to Swainson's Thrush (255 calls). However these two species
were about tied in estimated minimum number of individuals. The often
spectacular pre-dawn descent of thrushes between 5:30 and 6:30 am, when
dozens of thrushes can be heard, was strong on the morning of September 2nd
and 5th. Common Yellowthroats greatly increased this week, rivalling
American Redstart for most common warbler. There was close to a doubling in
the number of Northern Parulas and Black-throated Green Warblers.
Black-throated Blue and Cape May Warblers made a good showing. As to be
expected for the first week of September, Blackpolls began to increase. The
consistently low numbers of Wilson's Warblers and Tennessee Warblers so far
this year are worrisome. The highlight of the week was an Indigo Bunting at
10:57 pm on September 4th. A summary table for the week is presented below.
Additional information and formatted tables can be found on my website:

divided by 3 and rounded up to the nearest whole number.
