washed-out Yellowthroat, or ?? Farmington Connecticut, 4 Sept (1 Viewer)

This rather pale warbler popped up while I was looking through several Common Yellowthroat on the edge of Farmington Meadows near Hartford.

I have not adjusted the photo except for cropping and resizing.

I'd welcome thoughts on whether it is simply a pale immatureYellowthroat, or perhaps something from the Connecticut/Nashville/Mourning Warbler group?

Cheers
Mike

Dull Common Yellowthroat. The others mentioned all have more bright yellow below.

Thanks Andy
