Need help to identify this bird.

This little guy was on the ground under my feeder today. The markings look to me like a Kinglet, but a Kinglet is olive green, and this is way more yellow/green than olive.

Can anyone tell me what kind of bird this is?

What you have there is a Pine Warbler.

Thank you. It is the first one I have ever seen, and fortunately I had my 70-200 with 2x extender taking pics.

Beautiful bird.

Great shot

Thanks guys. That bird feeder pulls in some very colorful birds, especially in the summer.
