I'm an urban bird watcher. As such I see my share of pigeons, seagulls and little black birds that could be almost anything. Even though Philadelphia is 111 miles up river from the Atlantic Ocean, we get more than our share of seagulls -- especially along the Delaware Avenue parking lots from Home Depot and Wal-Mart where they scavenge from Christmas shoppers. I took this photo in Chicago on the banks of Lake Michigan, where seagulls perch on street lights like parking meters on Chestnut Street. Look there, a space just opened up.
