Tricky Geothlypis Warbler – Harrisburg, PA

Alex Lamoreaux|

Check out these photos taken by Sue Hannon of a Geothlypis warbler found today in Highspire Park near Harrisburg, PA. The bird is absolutely a Mourning OR MacGillivray’s Warbler, but which one? The eyering is thicker on the top of the eye and below the eye, but there is a narrow line connecting them behind the eye. The white-ish throat, blue patch on the upper breast, and long tail are also good field marks for MacGillivray’s Warbler, not to mention it is November 22nd. Let’s hope the bird sticks around for more birders to study and photograph tomorrow, but in the meantime – what do you think? Here is the link to all of Sue’s photos. There is only one record of MacGillivray’s Warbler in PA.

I have few examples of Mourning or MacGillivray’s to post as a comparison, but here is a photo of a MacGillivray’s Warbler that was captured and banded in South Carolina this fall by Josh Lefever.

  • We arrived at the Highspire Reservoir at about 3:30 and stayed to 4:25. It took a while but at about 4:15 the MacGilllivary’s, which is supported by Sue’s photos, was located in the brush just past the first bend in the boardwalk trail, before the bench and woodpile and behind a tree trunk with a “Private Property” sign. We were able to see the white eye arcs, not a complete eye ring, and the gray head, throat, and upper breast. Richard, because of a slightly different angle, also noticed the darker gray mark in the center of the gray/yellow breast line … also shown in Sue’s photos.
    Great find Sue and supper photos !
