While checking my ebird weekly route for shorebirds, none yet, I was trying to get an estimate on the number of Tree Swalows flitting around. A Merlin flew into the field and landed in a lone tree. The Tree Swallows coalesced (making an estimate of 100 a little easier) around the tree and began to mob the Merlin until it flew on.
