Yellow warbler

For the first time in 10 years, I saw today an adult male yellow warbler.

Because of the stunningly bright yellow color, I thought at first that it is an American Goldfinch. But moving closer, it was apparent this is different bird. A bit smaller, lacking the bold black marking of the goldfinch, and having prominent streaks on the breast. It was inside a bush, well hidden, and had it not flew from another tree into the nearby bush, I would not have noticed it.

I took a few photos of it. Here is the best one, cropped:
