Overall it was pretty quiet in the area this past week. On November 6 there
was a single Snow Goose and multiple migrating flocks of Tundra Swans at Rapids
Lake MVNWR. I counted 111 swans in 5 flocks. I also heard 3 additional
flocks that I was unable to find in the sky. Also at the unit were Killdeer,
several Bluebird, Purple Finch, and White-winged Crossbill. On November 8 at
Rapids Lake there were a single Bluebird, a couple Swamp Sparrow, and decent
numbers of Red-winged and Rusty Blackbird along with the usual residents. I
did have a flyover winter finch which was probably a Common Redpoll based on
the call. I assume that the American Bittern seen on November 9 reported by
Craig Mandel was the same bird I saw the day before, as the location described
was pretty much where I saw it. Note that most of the stretch along North
Shore Rd. is private property. Also on November 8 there were 3 Wilson's Snipe
at Chevalle wetlands.
Here is the breakdown of warbler species seen during the fall 2012
season followed by the 2008-2011 season percentages. Below that are the
adjusted numbers including this year's totals. Yellow Warbler,
Redstart, and Yellowthroat are excluded due to inconsistent counting of
these species over the years. I did a better job counting those
species this year but still likely overlooked some. Prothonotary and
Cerulean Warbler while not included in the percentages for all the years
are likely in the .02%-.04% range. In total there have been nearly the same
number(around 4000) of the below species counted during the 2008-2012 spring
seasons vs. those counted during the 2008-2012 fall seasons.
