Happily frolicking with our visitors at the bird feeders is our usual guest the tufted titmouse bird. It's a nice song bird with a series of clear whistle calls peter-peter-peter. Their territory, our neighborhood, have a specific songs differentiates from others. They hear and recognize each other solely by voice or song. There is also a distress call to warn others. Song call wording by Bird Songs, 250 North American Birds in Song. It's a delicate bird and very subtle in manner as I watch them.
