Hello birders in search of the "winged-warblers" in Vermont.
These fascinating birds are back, perhaps where you have seen them before, or in newly evolving habitats as abandoned fields begin to fill with shrubs and trees. Or maybe a familiar site has changed enough that it is no longer suitable.
This would be a good time to revisit, or visit for the first time, some documents which will tell you about the winged-warbler complex, what to look for when viewing the birds and identifying each individual, and how to submit to eBird.
----- In that website is this link to a detailed article about the two species and their hybrids. Two important aspect of these birds are (a) vocalizations heard can not be used to determine whether the bird singing is one or the other of the species or a hybrid, and (b) IDs are dependent upon combinations of many plumage characteristics. Here is the link:
*******----- The last page (page 7) of that article is a table to keep handy as you bird. It has eleven diagnostic features to look for, features that will help you decide if the bird you are viewing is one of the two species, a named hybrid, a hybrid of some mix of characteristics, or not possible to figure our from what you saw or heard.
