The larger wood-shrike has not yet been recorded from Chiang Rai 

 Province but is common in all other parts of our area. Its normal 

 range is the more open evergreen from 2,000 to 4,600 feet, but during 

 the cold weather it may be found in the dry, deciduous forest of the 

 plains and foothills, and then it might be seen in exactly the same 

 places as its smaller relative. 



The habits of this bird do not seem to differ greatly from those 

 of the preceding species, although the flocks are usually larger (up 

 to as many as 50 individuals) and are certainly noisier. 



Examples in post ju venal molt were collected June 3 at Doi San 

 Huai Wai, and numerous older specimens from all parts of the north- 

 ern range, taken between March 31 and October 17, are in molt. 

 Those shot between May 5 and June 13 are so badly worn and bleached 

 as scarcely to have taxonomic value. 



An adult male had the irides red-brown ; the bill black ; the feet and 

 toes dark plumbeous ; the soles yellowish ; the claws horny black. An 

 immature male had the irides gray-brown; the bill pinkish brown, 

 darker at the tip ; the feet, toes, and claws dark brown. Gyldenstolpe 

 notes that his adults had the irides yellowish brown, while immatures 

 had them grayish yellow. 



The adult male has a broad, black line along the side of the head 

 from the base of the bill to behind the ear coverts; the crown and 

 nape ashy gray ; the scapulars, back, and rump ashy brown, the feath- 

 ers of the last tipped white to form, together with the white shorter 

 tail coverts, a white patch or band; the feathers of wings and tail 

 ashy brown, edged with ashy rufous; the underparts white, suffused 

 on the breast with ashy gray or ashy fawn. The adult female re- 

 sembles the male but has the crown and nape concolorous with the 

 back and the eye stripe blackish brown. 



The birds of Thailand (north of Ko Lak) are exactly intermediate 

 between pelvica and annectens but form so stable a population that 

 Kinnear's name cannot properly be disregarded. From pelvica they 

 differ in just the characters pointed out by Kinnear (loc. cit.) ; from 

 annectens, in their superior size and ashy -brown {not ashy-gray) 

 upperparts. There is, however, a real possibility that vernayi may
