Worm hunting

These robins, which I saw on Monday the 19th, were my first sightings of robins this year.  There were actually four of them.  As I approached I saw a couple high in a tree, and at first wasn't sure what they were, as one of the birds was making a decidedly un-robin-like sound.  They were in the same spot where robins have been nesting for at least the last two years, so likely are returnees.  Sprigs of green grass are already poking through, brought on by the unusually warm weather.
