Crow

After Robbie (the robin) has been in to feed, and after a brief visit from the female blackbirds, generally next to arrive is this fella.
Colin the carrion crow, (I'm not very inventive with bird names) is the avian equivalent of a hoover.  Once he arrives, he locates the mealworms and has his not insignificant fill.
Despite their reputation, I have always liked corvids.  Their intelligence and characters make them, for me, an easy bird to enjoy watching.
