Mr Cutie, sorry can't help
It might be a female blue bird...they don't have as much color as the male. Have you seen it at the same time as a bright bluebird?
looks like a house wrenHelen
Maxi,On google images there was a bird that might look like your little guy or girl.... says it's a mountain blue bird which is the state bird of Idaho quite a distance from you though. I don't know.
We do have the bright bluebird --bright blue with rust breast - we have quite a few of these. We have see 3 of the unidentified birds
