THE BIRDS OF NORTHERN THAILAND 123 



20, 1935. De Schauensee collected a specimen on the Mae Kok at 

 Chiang Kai, January 6, 1929. I took examples at Chom Thong, No- 

 vember 28, 1931; Chiang Saen Kao, January 8, 1937; and at Ban Pa 

 Tao (on the Nan river, just south of our limits), April 10, 1937. 



One of my specimens had the irides dark brown; the apical half of 

 the bill black, the rest slaty blue ; the feet and toes plumbeous-olive ; the 

 claws blackish brown. 



The greenshank is much larger than any other sandpiper known 

 from our provinces and has the bill distinctly recurved. As usually 

 seen in Thailand, it has the upperparts generally gray-brown, the 

 feathers with black shaft streaks and narrow white edges ; the lower 

 back, rump, and upper tail coverts white; the underparts white, 

 sometimes with small blackish streaks on the breast.

The green sandpiper is a fairly common winter visitor to all our 

 provinces, though much less so than the wood sandpiper. At Chiang 

 Mai I recorded a single individual, July 11, 1931, but its stay there 

 normally extended from September 26 to April 1. In Stockholm are 

 six birds taken by Eisenhofer at Khun Tan, one collected by Gylden- 

 stolpe at Den Chai, and one by Fejos at Chiang Mai. I have speci- 

 mens from Mae Sariang, Ban Mae Wan, Sala Mae Tha, Chiang Mai, 

 and Ban Na Noi (April 2, 1937) and have observed it at numerous 

 other places. 



This species occurs on the plains wherever there is mud and shallow 

 water, usually in company with the wood sandpiper, but in smaller 

 numbers. 



My specimens had the irides dark brown ; the bill black, dark olive- 

 green on the basal half; the feet and toes dull olive-green or slaty 

 green; the claws black or horny brown. 



The green sandpiper may be confused with the wood sandpiper. 

 The former is a somewhat larger bird ; it has the upperparts darker, 

 usually more or less washed with oily olive-green, and the whitish 

 markings less distinct; rather heavier streaking on the breast; the
