Ornithology of Northern Borneo. 441 



some seasons districts on the coast are frequented by numbers 

 of a certain species, where in other seasons it would be im- 

 possible to procure a specimen. 



Pitta bert(B, of which species there are but few specimens 

 known, is, in all probability, a migrant from Formosa or 

 China to Borneo. 



P. cijanura of Java frequents the coffee-plantations, the 

 females being apparently separated from the males in certain 

 seasons, as I collected a number of males in one forest and 

 did not see a female, while in another forest I collected 

 nothing but females. 



The note of these birds is generally a two- or three- 

 syllabled whistle: that of P. erythrogastra, "Wow-wa" 

 whistled ; of others " Quop-quop ;" while P. ussheri has a 

 prolonged whistle. 



Pittas hop over the ground, moving along at a great pace. 

 The young have a plumage distinct from the adults, those of 

 P. muelleri and P. sordida having less white on the primaries, 

 pale pink abdomens, yellowish breasts, white throats, and 

 dull green backs, the head being brownish. The young of 

 the P. erythrogastra group are of a uniform brown, darker 

 on the back. 



The flesh of these birds is white and sweet.]

There is no difference in the colouring of the sexes ; but 

 the female has scarcely such a finely developed necklace. 



[I met with this beautiful Pitta on Kina Balu at from 2000 

 to 4000 feet in true forest, where it frequented the thick 

 bamboo-jungle. Iris black ; bill dark brown, greyish at base 

 of lower mandible ; legs slate-grey.]
