Hi All,

Nocturnal migration proceeded at an overall slower pace during the last week
August except for the last night. From the evening of 30 August to the
morning of 31 August, 1,845 night flight calls and an estimated 1,124 birds
were recorded. It consisted of a large flight dominated by American
Redstarts (estimated 151 birds) and Swainson's Thrush (114).

 

Most of the rare birds for the week occurred in this large flight and
included 1 Wood Thrush (0225 hours), 2 Scarlet Tanagers (0214 and 0244
hours), and 1 Dickcissel (0545 hours) on 31 August. Also an Indigo Bunting
was heard for the 3rd week in a row at 0226 hours on 27 August.

 

Overall for the week, the most abundant warblers were American Redstart (344
estimated birds), Chestnut-sided Warbler (218), Northern Parula (215),
Common Yellowthroat (178), Black-and-white Warbler (163), Magnolia Warbler
(147), and Ovenbird (106). With a total of 23 warbler species, Canada
Warblers were down to 84 estimated birds compared to 133 in the previous
week while there was a noticeable increase in Black-throated Blue Warblers
from 19 to 62 birds.

 

Thrush migration was in full force with an estimated 130 Swainson's Thrush
and 22 Veery for the week. Sparrow numbers were still very low and there
were just a few shorebirds.

 

A summary table can be found at
http://johnfkearney.com/Beaver_River_Yarmouth_County_Autumn_2018.html, and
nightly data is on eBird.

 

John
