Subject: [VTBIRD] Winged-warblers – observing, documenting, and submitting to eBird
Hello all spring birders!

With the warblers returning, it's time for this little note on how to
observe, document, and submit observations of the "winged-warblers":
Blue-winged
Warbler, Golden-winged Warbler, and their hybrids.

It takes work to observe critical features when viewing and photographing
(submit several photos per bird if possible) these birds. Understanding how
to recognize a hybrid is critical. It helps to recognize females, which are
often elusive. Audio recordings are very welcome. They, however, are of
little help in differentiating the two species, since the songs can come
from either species or a hybrid!

---- This article tells how to report winged-warbler submissions to eBird:
http://content.ebird.org/vt/news/golden-blue-winged-warbler
-potpourri-how-to-submit-to-ebird/

Note: in the categories where both species are mentioned, the article lists
Blue-winged first. Current practice lists Golden-winged first. For example
"Golden-winged/Blue-winged Warbler.

---- This Vermont Audubon website tells about the research on this group in
Vermont:
https://vt.audubon.org/conservation/golden-winged-warbler-conservation

---- The Audubon website refers you to this article:
https://vt.audubon.org/sites/default/files/static_pages/attachments/winged-
warblers._how_to_tell_a_pure_species_from_a_hybrid._7-10-19e.pdf

In the PDF are three tables that are very useful in highlighting critical
features when observing, documenting, and eBird-IDing.*You can use the
table to determine if a bird is a hybrid or pure species.*

Give a holler if you have any questions.

Good birding to all!

Best,
