I have been struck by the number of autumn events happening later than "usual"
this year. The most recent have been a big push of warbler activity during the
last week or so; and the many reports today of "late" Ruby-Throated
Hummingbirds.
Has anyone else noticed this trend? For example, are the big movements through
the Hawkwatch sights happening on time, or late this year?
