If an example of gyldenstolpei can appear in winter well within the 

 range of hessei, it seems likely that a similar tendency to wander may 

 be shown by occasional individuals of other northern subspecies ; such 

 stragglers could easily be responsible for the apparent instability of 

 many of the races discussed by Greenway in his valuable study of 

 winter-taken specimens (Auk, 1940, pp. 550-560).

This race of the lesser yellow-naped woodpecker is at present known 

 in our area only from the Thanon Thong Chai range and from Chiang 

 Saen, but it may confidently be expected to occur also in Mae Hong 

 Son Province and throughout Chiang Rai. 



The bird is almost confined to hilly districts, where both de 

 Schauensee and I found it only in evergreen forest. On Doi Suthep 

 it was very common from 3,500 to 4,500 feet, slightly less so down to 

 2,400 and up to 5,500 feet ; on Doi Ang Ka it was equally common in 

 clumps of trees in the semicleared valley below Pha Mon (4,000-4,500 

 feet) and in the dense evergreen but was not observed above 5,000 

 feet. It probably occurs at low elevations wherever the evergreen 

 reaches the plains, as at Doi Pha Sakaeng and Chiang Saen. 



This is a very striking species along shaded forest tracks, flying 

 before one (usually in pairs) from tree to tree and attracting atten- 

 tion by the shining gold of its erected nuchal crest. Stomachs I ex- 

 amined contained only ants. 



An adult male had the irides crimson ; the maxilla yellow with the 

 culmen blackish slate; the mandible bright yellow, tipped blackish 

 slate ; the feet and toes olive ; the claws horny plumbeous. 



The coloration of this bird not only varies a great deal individually, 

 but, as is the case with other woodpeckers, may be much altered by
