UROCISSA FXAVIROSTRIS ROBINI Delacour (?) 



Urocissa flavirosiris rohini Delacour, L'Oiseau, vol. 11, p. 393, 1930 (Fansipan, 

 Tonkin). 



Two immature males, Pak Chong, Jime 20, 1934. 



These two birds belong without much doubt to U. flavirostris , but 

 not very likely to the above form. They are placed. here only be- 

 cause it is the nearest race geographically. I have no immature 

 specimens of any of the forms of U. jlavirostris with which to com- 

 pare them but have immature specimens of U. e. magnirostris and 

 U. e. erythrorhyncha with which they do not agree. They are nearly 

 of adult size, but the tails have not reached their ultimate length. 



They differ from immature U. e. magnirostris in having the breast 

 and abdomen baryta j^ellow instead of white; the shafts, the inner 

 m.argins, and bases of the primaries beneath baryta yellovv' instead 

 of white or pinkish white; the under surface of the tail, shafts of the 

 feathers (except in the black subterminal bar), and the tips of tail 

 feathers yellow, instead of bluish with white tips; outer margins of 

 the primaries at the sinuation chamois instead of light blue; the back 

 a duskier less bright blue; the light occipital patch does not extend 

 as far forward or as far back and is of a more bluish cast with yellow- 

 ish bases to the feathers instead of wldte; the legs are j-ellowish in- 

 stead of reddish. The bills are dusky at the base, but the tips are 

 becoming horn color. 



They resemble the description by Sharpe ^■* of what he took to be 

 young of Urocissa flavirosiris and lie is probably right. 



The queer thing about securing the two above 5'Oung at Pak Chong 

 is that U. flavirostris is supposed to be a high-altitude species, and, 

 while the village is a mountain one, the elevation would hardly be 

 sufficient for a bird of this kind.

 Smith gives the color of the soft parts as: Eyelid, bill, and feet red. 



The immature male from the Khun Tan Mountams is of about 

 adult size. It resembles the adult, except the breast and abdomen 

 are pure white, only the throat and foreneck being washed with light
