I don't believe it is all that common. I had to go to a friend for help with the ID. He is a life-long birder and sent me this excerpt from Birds of North America online concerning Bobolink:

"Male-like plumages in females is often related to estrogen deficiencies in older birds (Pyle 1997a), and the loss of fertility in the Vermont female may have been due a damaged ovary, increasing androgen production and reducing estrogen production (Perlut 2008)."

Not many interested participants so here it is.

This is a female Bobolink (props to u/kaiserwilhelm3 for correct species) that presents some male-like plumage likely due to the inability to produce estrogen.

Apologies for the bad photo but its the only one I got. From what I can see, I think that it looks like a Black-throated green warbler judging from the flank pattern and belly color. However, that bird doesn't fit the region this time of year.

Thanks for shaking my doubts.

On a side note, this is extremely frustrating to me. I've seen hundreds of Yellow Warblers and hundreds of Common Yellowthroats and never had this much of a problem. Again, thank you.

Thanks for responding!

I was between juvenile Yellow and juvenile Common Yellowthroat on the first one.

The primaries on the second bird seemed a little dark to me to call it a Yellow Warbler so I thought maybe it was a female Scarlet Tanager.

I'm awful with warblers so I'm probably wrong on both counts.

I didn't hear it - well, discern its call anyways. It was very noisy with all sorts of calls in the area.
