Hi John,=20

I am wondering what your data is showing regarding this year's migration as=
 opposed to last year? In general trends. Are there more birds leaving earl=
ier? Or is it about the same? I am not seeing many migrants here yet, and I=
 wonder if those who usually hit my patch are late or early?! Or have they =
changed their patterns in terms of route... Not sure why, but there seems t=
o be a change from my limited viewpoint and information. So I'm curious if =
you are seeing differences.

6462984WordSection1 {}-->Hi All,It was a busy week for nocturnal migration =
at Carleton, Yarmouth County. There was a total of 1,383 calls at a rate of=
 198 calls per night. There was an estimated minimum of 1,117 birds. Warble=
r composition fell to 79% of calls due to the influx of Swainson=E2=80=99s =
Thrushes and Veeries. The most common birds for the week were Common Yellow=
throat (190), American Redstart (160), Magnolia Warbler (152), Northern Par=
ula (125), Black-and-White Warbler (116), Swainson=E2=80=99s Thrush (88), a=
nd Black-throated Green Warbler (64). There was a more than average flight =
of Wilson=E2=80=99s Warbler, with 37 flight calls recorded. The peak for th=
e week and for the autumn season thus far was the night of 2-3 September wh=
en 469 calls were recorded. Rare birds for the week included 4 Prairie Warb=
lers, 2 Pine Warblers and 1 Indigo Bunting. A sparrow recorded at 10:22 pm =
on 6 September was a possible Seaside Sparrow. A discussion of this flight =
call can be found on at my website at http://www.johnfkearney.com/SESP.html=
. Additional graphics of the autumn nocturnal migration at Carleton can be =
seen at: http://www.johnfkearney.com/Carleton_YarmouthCounty_2016.html. A s=
