Hi All,
The highest nocturnal count of the autumn so far at Carleton, Yarmouth
County, occurred this week on the night of 9-10 September. This peak, with
542, calls was roughly equivalent in number to the peak for the entire
season last year that occurred on the night of 16-17 September. After the
9th of September, the strength of migration was light to moderate, giving a
total of 926 calls for the week or a mean of 132 per night. Warblers
composed 87% of all calls, thrushes, 7%, and sparrows, 4%. The most common
species for the week were Northern Parula (103 calls), Common Yellowthroat
(93), Blackpoll Warbler (85), Black-throated Green Warbler (82), Magnolia
Warbler (71), and Swainson's Thrush (61). A good flight of Cape May Warbler
(30), and Black-throated Blue Warbler (21) continued this week. Rare birds
for the week included 1 Upland Sandpiper, 2 Pine Warblers, 1 Prairie
Warbler, and 1 Vesper Sparrow.
There continues to be a good correlation between the density of echoes on
the weather radar at Caribou, Maine and the number of flight calls detected
acoustically at Carleton, Nova Scotia. This was true on the night of 9-10
September when parts of the sky in Maine had an echo (bird) density of 600
per cubic kilometer. This was the highest I have seen this year. The echoes
moved in the direction of south-southeast in the early evening and veered to
south-southwest as the night progressed. This seemed to indicate a movement
to the coast from northern New Brunswick/Maine and then along the coast of
Maine.
Further details along with graphs and tables can be found at my website:
http://www.johnfkearney.com/Carleton_YarmouthCounty_2016.html. A summary for
the week can be found in the table that follows.
