The fish in the bill of this this Least Tern appears to be a juvenile bass (Micropterus sp.). I would guess Large-mouth bass (M. salmoides), but the fact that the spotting along the dorsal line is so heavily broken suggests a small mouth (M. dolomieui). If the bill length is close to the average of 28 mm (Birds of North America Online), then the fish is at least 60 cm or a little more than 2 bill lengths.
