The shikra is a very common permanent resident throughout north- 

 ern Thailand. In the vicinity of Chiang Mai it occurred everywhere 

 on the plain and ascended Doi Suthep, along the trails and in the more 

 open forest, to 3,500 feet. A specimen in Hannover was taken by 

 Eisenhofer at Pha Hing. The same collector sent to Stockholm one 

 example from Huai Pu, and no less than 19 from Khun Tan. I took 

 it at Chom Thong, Ban Nong Khiat, Ban Tha Nong Luang, Chiang 

 Saen Kao, Ban Noi, Ban San Sai Mun, Ban Mae Dok Daeng Nai, 

 Chiang Mai, and Doi Suthep and have seen it in Nan Province. 



This is a fearless little hawk, more often observed in the neighbor- 

 hood of human habitation than in wilder areas. One frequently seen 

 in my compound at Chiang Mai used to conceal itself in the crown 

 of a coconut palm, whence it would dash out after some unsuspecting 

 myna ; a great chase would then take place, the pursuer and pursued 

 wheeling and dodging among the trees until the starling at last 

 found shelter in the dense heart of a palm or fell victim to the bandit. 

 One of my specimens, a large female, was shot while in the act of 

 tearing to pieces a dove (Streptopelia c. tigrina) , and de Schauensee 

 (1929) took examples that had fed, one on a small bird, another on 

 a small rodent; most stomachs examined, however, have contained 

 insects, frogs, and lizards. A bird observed in northern Nan Province 

 was beating the edge of an extensive grass fire, catching grasshoppers 

 and other insects as they tried to escape the flames. 



Apparently no birds in actual breeding condition have been taken 

 in our area. Eisenhofer took juveniles at Huai Pu, June 4, 1912, and 

 at Khun Tan, June 6, 1913, while Gyldenstolpe took similar examples 

 at Pang Hua Phong, May 26 and 27, 1914. A number of my speci- 

 mens had paired ovaries. 



An adult male, taken by me on August 15, retains a few traces of 

 the brown subadult plumage on the head and back. The third pri- 

 mary on each side has been molted and the new feather is still in 

 sheath.
