In my book there are five varieties of titmice (laughing in my head). The field mark they all share is a tiny crest on their tiny little head. And big, dark eyes. However, they're all a wee bit different from one another. Most titmice live out west. In Iowa we have the Tufted Titmouse (still laughing in my head). Whenever I see one of these little guys in my lawn I'm kind of surprised by them, they're funny. This is how they're described in the book.
(this describes the field marks) A small, grey, mouse colored bird with a tufted crest. Forehead and underparts pale, sides rusty. Their song is a whisled "peter peter peter peter (laughing in head) or Here Here Here." Their sound is similar to a chickadee but more nasaly, wheezy and complaing.
Nasaly, wheezy, and complaining? If I was a titmouse I'd be offended. I know I make fun of the word titmouse a lot but when it comes down to it, what a great title for a tiny, discreet, bird. Titmice.
