Another ID Request - Warbler
I don't think this a yellow warbler, what with the lower black eye stripe? Any help would be great.
Location - Northwest Jersey; yesterday.
Thanks in advance,
Rebecka

I'm no expert, and I approach ID of warblers with fear and trembling, but my call is female prairie warbler (dendroica discolor)

I'm not an expert either, but I agree that it is a prairie warbler, but I think it is a male.

Could be. I wouldn't argue either way.

Female Prairie Warbler. Slightly atypical plumage, but there's not much else it can be.

I agree, a Prairie Warbler. A common nesting bird in NJ.

From Bill Boyle's A Guide to Bird Finding in New Jersey

Uncommon migrant in overgrown fields; fairly common summer resident in overgrown fields (especially those with Red Cedars) in the northwest and very common summer resident in the Pine Barrens. Regular in late April-early May and September at the usual migrant spots; during the breeding season: ****Glassboro Woods, Lebann, Wharton, Whitesbog; ***Brigantine, Cape May, Dividing Creek, Tuckahoe.

For my learning purposes I am wondering why you guys think its a female? The black lines on the face look pretty dark and the book I was looking at they seem more prominent in the males. Thanks in advance.

The male has darker and bolder stripes. Also, more of them, I think.

Good question, Scott. Note that I did not say male or female as I think this could be either depending on the date the image was made, and I think Jim has hedged his ID with this "Slightly atypical plumage" line as well.

You can see the typical variation in Prairie Warbler plumage on Plate 19 in Dunn & Garrett's Warblers volume in the RTP series, where it shows that first fall males can look almost as plain as breeding females.

But assuming that Rebecka photographed this bird recently in NJ it should be a breeding adult.
