where it crosses the Choeng Doi road a few miles east of Chiang Mai, 

 and I have also seen this species along the railway between Chiang 

 Mai and Lamphun. 



In 1936 (loc. cit.) I related as much as I knew of the history of this 

 bird's introduction. I may repeat here that a few individuals were 

 brought from Java by H. H. the late Chao Kaeo Nawarat na Chiang 

 Mai, at the time of his visit to that island, and that they were set free 

 east of the town near where the railway station now stands. In time 

 the species may be recorded at any cultivated part of the great Chiang 

 Mai plain, but it is not likely ever to cross the mountains into the 

 neighboring provinces without human assistance. 



A specimen taken on February 15 had the gonads greatly enlarged. 



On June 28, 1930, I listened to a joint concert by what seemed to 

 be a mated pair perched at the top of a tree. The song was a soft 

 whistled coo-d-coo-coo or coo-d-d-coo-coo or coo-d-d-coo-coo-coo, the 

 sound resembling that made by blowing into the mouth of a bottle. 



A female had the irides pale gray ; the orbital skin light blue ; the 

 bill plumbeous-blue, darker over the nares and becoming light blue at 

 the base of the maxilla ; the tarsi blue- white behind, the scutes in front 

 dark brown, edged blue- white ; the soles yellowish ; the claws brownish 

 horn. 



This is the smallest of the northern pigeons ; it is usually seen on 

 the ground in pairs. The adult has the forecrown and throat ashy 

 gray; the hindcrown light brown; the nape closely barred blackish 

 brown and brownish white; the remaining upperparts light brown, 

 with irregular bars formed by the narrow blackish tips of the feathers ; 

 the central rectrices light brown, the outer blackish brown with broad 

 white tips; the sides of the breast closely barred black and white, 

 changing to black and pale buff on the flanks ; the center of the breast 

 vinaceous-pink, changing to pale buffy on the abdomen and to white 

 on the under tail coverts.
