Schauensee ^° recorded a specimen from Chiengmai, February 1 ; 

 Herbert ^^ says it is said to breed at Bang-pa-in and Ayuthia and 

 winters at Wat Koh Yai, Sambok; Gyldenstolpe ^^ reports that the 

 night heron is only a winter visitor to Siam. It probably breeds in 

 limited numbers, how^ever, in suitable localities. It has not been 

 recorded from Peninsular Siam but probably occurs there in winter. 

 This heron has a wide range, breeding from Holland and Germany 

 east to Japan and China and south to India, Indo-Cliina, Siam, the 

 Sunda Islands, the Plulippines, and Africa.

(Sumatra). 



One immature male, Hupbon, near Sriracha, October 22, 1931; one 

 immature male, Kao Sabap, November 8, 1933. 



Dr. W. L. Abbott collected an adult male at Lay Song Hong, 

 Trang, November 25, 1896; and two immature males in the Langkawi 

 Group (Pulo Lada, November 30, 1899, and Pulo Terutau, November 

 16, 1903). 



Dr. Abbott describes the soft parts of the adult male from Trang as 

 follows: Iris greenish yellow; orbital skin green; biU dark horn brown 

 above (the label here has had the ink dissolved by grease and the 

 color of the lower mandible cannot be read); feet brow^nish green, 

 yellowish behind toes. 



This form ranges from Ceylon and the Malabar coast east to 

 Assam, Burma, Siam, Indo-China, and south through Peninsular 

 Siam, to the Malay States, Sumatra, Java, Borneo, and the 

 Philippines. 



Besides those listed above, specimens have been obtained in north- 

 em and eastern Siam by other collectors, and the bird probably occurs 

 throughout the country in suitable locaUties. Owing to its nocturnal 

 habits, however, it is seldom taken. WUUamson informed Robinson 

 and KHoss ^^ that he found it breeding in heavy forest at Pak Chong 

 in June and August.
