THE BIRDS OF NORTHERN THAILAND 99 



Northern Thai birds are inseparable from topotypical specimens of 

 bicalcaratum. 



The provenance of Lowe's bailyi (Ibis, 1925, p. 482) is unknown but 

 is believed by the describer to lie somewhere in our provinces. The 

 male of this form is said to have the ground color of a darker brown 

 than bicalcaratum and the spotting almost pure white rather than buff. 

 Northern birds I have seen do not fit this description, nor do the odd 

 wing and tails from Lorn Sak, just beyond our limits, mentioned (1938) 

 by Riley. 



PAVO MUTICUS MUTICUS Linnaeus 



Javanese Green Peafowl 



[Pavo] muticus Linnaeus, Systema naturae, ed. 12, vol. 1, 17G6, p. 268 (Japan, 



error ; Java designated as type locality, by Hartert, Nov. Zool., vol. 9, 1902, 



p. 538).

(Den Chai, Pak Pan) ; 1916, p. 159 (Chiang Saen) ; Ibis, 1920, p. 738 



("Throughout the country"). 



The peafowl is well distributed in the northern lowlands, except in 

 the immediate vicinity of the larger towns, where it has been ex- 

 tirpated. Gyldenstolpe heard its calls in the deciduous forests near 

 Den Chai and Pak Pan and later collected one at Chiang Saen. Eisen- 

 hofer sent to Stockholm two males, taken at Khun Tan in 1915. It is 

 common in the neighborhood of Chiang Dao, where I took an adult 

 female, January 1, 1932. It is said to occur in the dry forests at the 

 foot of Doi Ang Ka. In Nan Province it appears to be common every- 

 where and is seen by all who travel down the Mae Nan by boat. In 

 December 1935 I saw a flock at the edge of the Mae Ping near Ban 

 Mut Ka. 



These giant pheasants inhabit the deciduous jungle, the more open 

 evergreen, and the second growth. If they must go uphill to escape 

 clanger, they run rapidly, making as much noise as deer in the dry 

 leaves ; on the level or downhill they leave the ground after a running 

 start and fly strongly, sometimes taking refuge even in the highest 

 trees. In December and January 1931-32, 1 found them in large bands 

 along the Mae Ping east of Chiang Dao, coming down at dusk and 

 dawn to feed and drink in the ricefields along the river and spending 

 the hot hours of the day on the dry, low hills of the left bank, where 

 they rested on the ground, concealed among the clumps of coarse grass. 



Gyldenstolpe records that his immature male had the irides brown ; 

 the bill horn color ; the feet and toes brown. 



Since the peafowl are such familiar birds to residents of Thailand 

 and only one species is likely to occur in the Kingdom, no detailed 

 descriptions need be given.
