 central feathers often immaculate ; the throat white or rufous- white, 

 each feather with a narrow dark gray shaft streak; the under tail 

 coverts white; the remaining underparts varying, according to age 

 of specimen, from pinkish rufous with indistinct, narrow buffy bars 

 to immaculate vinaceous-pink ; the under wing coverts white, washed 

 with buff. Immature birds have the crown brownish slate; the 

 remaining upperparts dark brown; the exposed portion of the tail

This large accipitrine is not common but seems to be generally dis- 

 tributed in the northern provinces throughout the year. A female 

 in the Stockholm Museum, taken by Eisenhofer at Khun Tan in 

 1914, is probably the bird listed by Gyldenstolpe in 1915 ; a specimen 

 in Hannover was taken by the same collector at Pha Hing, May 4, 

 1912. I obtained a male about 6 km. south of Muang Chiang Dao, 

 August 17, 1935. 



Gyldenstolpe has observed that the species seems to avoid evergreen 

 jungles and the lower valleys with their dense vegetation, and it was 

 met with only in the deciduous forest or in thin tree jungle. My own 

 experience has been precisely the same. The stomach of my specimen 

 contained small frogs. 



The bird had the irides golden-orange ; the orbital region and lores 

 greenish yellow; the cere and rictus yellow; the maxilla black; the 

 mandible plumbeous, tipped black; the feet and toes bright yellow; 

 the claws black.
