Haven't a clue!

I think it is a Sparrow but one I haven't seen before. It landed in the front yard this morning. Thanks for your help.

Possible, Field Sparrow

Thanks for the reply Burd. I don't think it is a Field Sparrow as I see lots of them and this is one that I don't think I've seen before. This bird appeared a bit larger than a Field Sparrow and didn't "act" like one either. I am thinking it is a juvenile but I am wrong so much of the time. Thanks again!

A rather dull immature white-crowned...

Thanks Altagardener...I never thought about a White-crowned!
