I promised you some pictures of the robin nesting outside my kitchen window. Below is a mosaic of images – click to enlarge!
The robin on the far right is, as far as I can determine, the male (American robins can’t always be sexed by plumage alone, or so Wikipedia tells me!)
The central image is the newest – shot just a couple of hours ago. I’m fairly convinced, based on the beak and eye markings, that the robin who began building the nest is not the one who occupies it now.
