I'm a couple days late getting in the report on nocturnal migration over
Antigonish County this past week. Warbler migration is well underway. This
is being noticed by a few other people doing nocturnal monitoring in other
parts of North America, as far away as Texas. It also seems to be earlier
than normal. So this past week I recorded 708 night flight calls. Of these,
636 or 90% were warblers. The most common warbler was American Redstart with
182 flight calls (29% of warblers). However, the American Redstart is easy
to identify by night flight call whereas many other warblers are quite
difficult. Other warbler species may also be quite numerous but it will not
be as apparent since they are lumped into more general categories. Here is
the summary of night flight calls for the week starting the evening of May 3
and ending the morning of May 10.
