adults select more optimal (i.e., large) prey than do juveniles, which 

 indiscriminately feed on prey they encounter. This may be the result 

 of larger animals being able to choose from a greater range of prey 

 sizes, whereas smaller individuals are largely restricted to small prey, 

 as is apparent in P. crucifer (Oplinger 1967). This shift would account 

 for the lower diversity of prey species taken by adult P. ocularis. 

 Second, the adult sample used in our comparisons consisted entirely 

 of males. Several authors have reported a sharp decline in feeding 

 activity by adult male frogs during the breeding season (Jenssen and 

 Klimstra 1966, Lamb 1984). The males in our study were not breeding 

 (the pond was completely dry) and only sporadically calling at the 

 time of collection (5 June), although breeding had been previously 

 observed at this site in March. Mount (1975), however, reported breeding 

 congregations of P. ocularis as late as 29 July in nearby Houston 

 County, Alabama, and Harper (1939) recorded vigorous chorusing in 

 the Okefenokee during August and September. Therefore, since P. 

 ocularis does breed throughout the summer, we cannot rule out the 

 possibility of lower feeding activity in adult males during the time of 

 our collections.
