As you have no doubt noted, the "winged-warblers" are back. Now is a
good time to read, or read again, the article Vermont eBird has
published on its website:
The article will help you know what to look for if you see one of these
birds, and what to do if you hear one but don't see it. There are
detailed instructions as to how to report what you saw or heard.
Please contact me if you have any questions.
And thanks for all those reports to eBird! Every one of them helps the
on-going research and conservation activities for this complex by
Audubon Vermont. Read about the project at:
Best wishes for good birding.
