Kath identified them as a pair of Ruby Crowned Kinglets. Here's what they look like. The photo is not mine, it comes from a website on bird identification by the Cornel Lab of Ornithololgy. This is the adult male and he's really very tiny. He and his mate are in constant motion, darting down onto the road and then up into the bushes, flicking their wings as they go. Isn't he just the cutest thing?
When we lived in the city we didn't pay much attention to birds but up here on the hill there's much more evidence of bird life, especially across the street at the organic farm. Tomorrow I'll show you what they're growing there now. Hint: it's a very trendy vegetable and the word begins with K.
