The pale-legged willow warbler is known from our area by only two 

 specimens : A male collected by Gyldenstolpe at Den Chai, February 

 8, 1912, and an unsexed bird taken by de Schauensee on Doi Suthep, 

 5,000 feet, February 27, 1933. 



Gyldenstolpe notes that his example had the irides dark brown; 

 the bill horn color ; the feet and toes pale brownish yellow. 



This species has the upperparts olivaceous-brown, dark and dull 

 on the head but bright on the mantle and strongly suffused with 

 ochraceous on the rump, upper tail coverts, and rectrices; the wing 

 like the mantle but with the greater and median coverts tipped buffy 

 yellow or yellowish white to form two indistinct bars; the lores and 

 postocular streak blackish olivaceous-brown; the long, broad super- 

 cilium pale buff or buffy white; the underparts white, more or less 

 strongly washed with brownish buff along the flanks; the under tail 

 coverts pale buff or pale buffy yellow ; the bend of the wing and the 

 axillaries pale buffy yellow; the under wing coverts white (sometimes 

 tinged with pale buffy yellow). 



PHYLLOSCOPUS CORONATUS CORONATUS (Temminck and Schlegel) 



Japanese Crowned Willow Warbler 



Ficedula coronata Temminck and Schlegel, in Siebold, Fauna' Japonica, Aves, 

 1847, pp. 48-50, col. pi. 18 (Japan). 



Phylloseopus occipitalis coronatus, de Schauensee, Proc. Acad. Nat. Sci. Phila- 

 delphia, 1934, p. 230 (Doi Suthep, Doi Chiang Dao). 



Acanthopneuste occipitalis coronatus, Deignan, Journ. Siam Soc. Nat. Hist. 

 Suppl., 1936, p. 117 (Doi Suthep, Chiang Mai). 



At one time I believed the crowned willow warbler to be a common 

 winter visitor to all the northern provinces, from the level of the plains 

 to at least 5,500 feet and, at Chiang Mai, occurring from September 

 26 (1936) to March 1 (1933). It now appears that I have confused 

 coronatus in the field with the various forms of reguloides, and the 

 true status of the former must for the present remain in doubt. I 

 have collected a specimen of coronatus at Ban Sa-iap (Phrae Province) 

 as early as September 8 (1936). 



This is probably the willow warbler with conspicuous coronal bands 

 frequently encountered in gardens and orchards, associated with P. i. 

 inornatus. 



A male had the irides brown ; the maxilla dark brown ; the mandible 

 horny yellow ; the feet and toes horny brown ; the claws horn.
