Abstract: Large water-snails (referred to as Pomacea flagellata by Smithe, The birds of Tikal, Natural History Press, 1966) were a second item of prey taken at the water edge. A wood-rail, after finding a snail, spent from one to four minutes pounding at it on the ground before tossing the shell away and devouring the body as two separate morsels. I was able to recover the particular shell with certainty (other shells were lying about) on three occasions and found that the bird had made a hole about 0.6 cm in diameter in the side of each shell. Limpkins (Aramus guaraunu) and Everglade Kites (Rostrhamus sociabilis) have specially adapted bills that enable them to feed
