This handsome cuckoo occurs in the lowlands of northern Thailand 

 as a rather common bird of passage in spring and autumn and as a 

 very rare summer resident ; it has never been recorded with us in win- 

 ter. In the neighborhood of Chiang Mai the migration periods ran 

 from February 9 (1929) to March 14 (1936) and from September 3 

 (1930) to November 16 (1929). Eisenhofer sent to Hannover two 

 specimens from Pha Hing, taken April 23 and May 1, 1912; the same 

 collector sent to Stockholm five undated examples, including one 

 juvenile, from Khun Tan. The occasional presence of this species in 

 summer is indicated by a juvenile brought to me at Chiang Mai, June 

 19, 1935, and by an adult observed at a village on the Mae Ping, near 

 Mae Kim, July 27, 1935. 



At Chiang Mai I saw only solitary individuals and always found 

 them perched in giant bamboo or on a coconut palm in the immediate 

 vicinity of houses or even in the heart of a village. In Nan Province, 

 however, in the spring of 1936, I met with a loose flock in a wholly 

 uninhabited area overgrown with bamboo. Attention is sometimes 

 drawn to this cuckoo by its raucous scream, but in northern Thailand 

 it is usually silent. Specimens I examined had fed entirely on cater- 

 pillars. 



A bird from Chiang Mai, September 27, has not completed the post- 

 juvenal molt : it still has the ju venal quills in wings and tail and a few 

 brown feathers in the crown. 



This immature example, a male, had the irides brown; the bill 

 black, with the basal half of the mandible orange beneath; the rictus 

 and interior of the mouth orange; the feet and toes plumbeous; the 

 claws horny brown. 



The adult has the head and conspicuous crest black glossed with 

 steel blue; a narrow white nuchal collar; the wings rufous; the re- 

 maining upperparts black, glossed with steel green on scapulars and 

 back, with steel blue on the tail; the throat and upper breast fer- 

 ruginous, fading to ferruginous-white on the abdomen; the thighs 

 smoky brown ; the under tail coverts black, glossed with steel blue.
