What warbler?

[Taylorjane]

This little bird was seen in my backyard in SW Montana. I believe it's a Nashville Warbler but not 100%.  Any help with a positive ID would be greatly appreciated. The photos aren't great. It was quite active, and I was taking the pictures through a window.

Nashville Warbler is correct.

That's a good bird for Montana if I'm not mistaken. I don't think I've ever had one up there.

I checked eBird and sightings are few around here, and in all cases the past couple years it's only been one that's been observed.

Nice Find!

Thank you all!  I wanted to be sure on this one as it would be a life bird for me.

Nashvilles are regular in small numbers spring and fall in Colorado, particularly on the West Slope. The species should be expected on MT’s West Slope and the eBird map shows such: https://ebird.org/map/naswar?neg=true&env.minX=&env.minY=&env.maxX=&env.maxY=&zh=false&gp=false&ev=Z&mr=1-12&bmo=1&emo=12&yr=all&byr=1900&eyr=2021
