_Periplaneta americana_, Germany, Frankfurt am Main, Zoological Garden (Lederer, 1952): Newly molted cockroaches were accepted as food, but others were usually passed by or consumed unwillingly. Order SERPENTES Family COLUBRIDAE =Heterodon platyrhinos= Latreille _Synonymy._--_Heterodon contortrix_ [Dr. Doris M. Cochran, personal communication, 1957]. _Common name._--Hog-nosed snake. _Experimental prey._--_Periplaneta americana_, U.S.A. (Moore, 1946): Cockroaches containing infective acanthellas of _Moniliformis dubius_ were fed to one snake. =Garter Snake= _Experimental prey._--_Blatta orientalis_, U.S.A. (Rau, 1924). Class AVES The cockroach is always wrong when arguing with a chicken. _Spanish proverb_ (HARTNACK, 1939) Arboreal cockroaches hidden in and under bark are much more likely to be encountered by birds than by other predators, and insectivorous birds undoubtedly consume many more cockroaches than the few records would indicate. Most of the records we have located identify the birds at least by common name. Where possible we have given the scientific names for those birds whose common names are recognizably specific. We have followed the systematic classification of Wetmore (1940). Figuier (1869) stated that poultry and owls are very fond of cockroaches. Perkins (1913) made the general statement that some of the native birds of Hawaii are partial to the endemic _Allacta similis_. Asano (1937) stated that in Japan natural enemies of cockroaches may be found in the Galliformes, Strigiformes, Passeriformes, and Piciformes. Although Lederer (1952) successfully fed newly molted _Periplaneta americana_ to insectivorous birds in the Zoological Garden, Frankfurt am Main, _Blattella germanica_ were preferred by these birds. The following records are of specific birds feeding on cockroaches. Order ANSERIFORMES Family ANATIDAE =Domestic duck= _Natural prey._--_Pycnoscelus surinamensis_, Australia (Fielding 1926): The ducks became infected with Manson's eye worm of which _P. surinamensis_ is the only known intermediate host. Cockroach, Bermuda (Jones, 1859): "All kinds of poultry feed greedily upon the cockroach; tame ducks spending entire moonlight nights in their capture." Order GALLIFORMES Family PHASIANIDAE =Bambusicola thoracica= Temminck _Common name._--Kojukei. _Natural prey._--Cockroaches, Japan (Asano, 1937). =Gallus= sp. _Common name._--Jungle fowl. _Natural prey._--_Periplaneta australasiae_, Hawaii (Schwartz and Schwartz, 1949). =Phasianus calchicus karpowi= Buturlin _Common name._--Korean pheasants. _Experimental prey._--_Blattella germanica_ and _Periplaneta picea_, Japan (Asano, 1937): Adults of these cockroaches were devoured at once when they were fed with the heads cut off. =Phasianus= sp. _Common name._--Pheasant.
