There is one interesting record which seems to suggest that Swinhoe's Bee-Eater (_Melittophagus swinhoei_) may exercise that discrimination in the butterflies it attacks which is demanded on the mimicry theory. Lt.-Col. Bingham on one occasion in Burma noticed this species hawking butterflies. He records that they took _Papilio erithonius_, _P. sarpedon_, _Charaxes athamas_, _Cyrestis thyodamas_, and _Terias hecabe_, and probably also species of the genera _Prioneris_, _Hebomoia_ (Pierines), {111} _Junonia_ and _Precis_ (Vanessids). And he goes on to say: "I also particularly noticed that the birds never went for a _Danais_ or _Euploea_, or for _Papilio macareus_ and _P. xenocles_, which are mimics of Danais, though two or three species of _Danais_, four or five of _Euploea_, and the two above-mentioned mimicking _Papilios_ simply swarmed along the whole road[62]." Marshall also quotes a case of attack by a green bee-eater on a _Danais_ in which the butterfly was caught and subsequently rejected, after which it flew away. Little stress, however, can be laid upon this case in view of the more recent data brought together by Col. Manders and Mr Fryer. Discussing the attacks of birds on butterflies in Southern India and Ceylon, Col. Manders gives the following quotation[63] from a letter of Mr T. N. Hearsy, Indian Forest Service: "Coimbatore, 6. 6. 10.... I have frequently seen the common green bee-eater (_Merops viridis_) and the king-crow (_Buchanga atra_) take butterflies on the wing, the butterflies being _Catopsilia pyranthe_, _C. florella_, _Terias hecabe_ and _Papilio demoleus_. The bee-eater I have also seen taking _Danais chrysippus_ and _Danais septentrionis_, and I remember to have been struck with their taste for those latter...." Col. Manders also brings forward evidence for these Danaids and Euploeas being eaten by Drongos and by the paradise flycatcher. Still more recently an interesting contribution to the matter has been made by {112} Mr J. C. F. Fryer[64]. The Ashy Wood-swallow (_Artamus fuscus_) had been recorded on two occasions as having attacked _Euploea core_. Mr Fryer was fortunate in coming across this bird in the gardens at Peradeniya, near Kandy, at a time when _Euploea core_ and _Danais septentrionis_ were particularly abundant, and he watched a number of them systematically hawking these presumably unpalatable species. As he observes, "in Ceylon a resemblance to the genera _Danais_ and _Euploea_ is doubtfully of value; in fact in the neighbourhood of Wood-swallows it is a distinct danger." Fryer also noted that the mimetic forms of _P. polytes_ were taken as well as the non-mimetic.
