Tufted Titmouse

I love these little things! They're like little grey cardinals, sort of. They make that high pitched chirp you can hardly hear. We have 4 houses up and we always get them in all of the houses. Well, at least when the sparrows don't get in there first.

I enjoy these cute birds also. So far I haven't had any nest in my boxes. I only have Bluebird houses. What kind of box do they like at your place?
