Hi All,

The volume of nocturnal migration over Carleton, Yarmouth County, was about
the same this week as the previous week. A total of 221 night flight calls
representing an estimated minimum number of 181 individual birds was
recorded. Similarly, the proportions of bird families mirrored last week's
with sparrows accounting for 50% of calls, warblers 43%, chickadees 4%, and
thrushes less than 1%. The most common bird was White-throated Sparrow with
53 calls, followed by Yellow-rumped Warbler (47), and Savannah Sparrow (19).
Common Yellowthroats keep coming. Nine calls of this species representing at
least 7 individuals were recorded. Other late warblers included Magnolia (1
individual), Nashville (2), Ovenbird (2), and Black-throated Blue (1). Other
seasonably appropriate warblers included Blackpoll (6 individuals), Palm
(3), and Orange-crowned (2). One night flight call closely resembled the
characteristics of a Hooded Warbler. Unidentified Melospiza flight calls,
probably Swamp Sparrows, continued with a total of 13 calls. Other sparrows
included  Song Sparrow (9), Chipping Sparrow (1), and Clay-colored Sparrow
(1). There was a single Hermit Thrush recorded. This report is followed by a
summary table. More detailed information, including graphs of seasonal
trends and peak count dates, can be found at:
