In order to gain a better understanding
of the diversity, timing, and magnitude of the
waterbird migration
over Lake Michigan, I have been conducting
fixed-position watches
from Muskegon County beaches for the past five years.
So far this
fall, beginning September 7, I have conducted
21 such surveys.
When
the phenology and weather are favorable, the numbers of passing birds can be most
impressive. Such was the case
yesterday (
November 6), when I tallied
387 southbound Common Loons at
Hoffmaster State Park. The flight, which continued for at least three hours, was so strong that I counted as many as 27 loons during a single minute. The total easily
established a new daily record for the lake watch.
Other highlights this season include:
267 Gadwall on October 25
31 Black Scoters on October 24
120 Bufflehead on November 6
1,167 Double-crested Cormorants on
September 28
135 Bonaparte's Gulls on October 16
1 jaeger on October 17
first Great Black-backed Gull on
October 19
