I have discovered something I probably already knew – that there was a great reason my cats used to keep their little noses pinned to the window when there was a bird in the vicinity. They are such a delight to behold (birds, I mean, though cats are, too)! We have a nest on our porch – will write more about it later, as until the babies have fledged, I shall not exhale. But in the meantime, enjoy this video of birds singing opera – oh yes, they are!
