De Schauensee's specimen had the irides creamy yellow ; the orbital 

 region olive-yellow ; the bill black, with base, nares, and rictus olive- 

 yellow; the feet and toes bluish olive. My juvenile had the irides 

 yellow. 



The juvenile has the upperparts generally pale sandy rufous (scap- 

 ulars darker), streaked with black on crown and scapular tract, nar- 

 rowly barred elsewhere, and with a pair of parallel black lines sep- 

 arating the center of the back from the scapulars and another similar 

 pair at the sides of the rump; a black streak from the base of the 

 mandible below the eye to the lower edge of the ear coverts ; the throat 

 buffy white; the lower neck and upper breast pale sandy rufous, 

 indistinctly streaked blackish; the lower breast and flanks pinkish 

 buff; the belly whitish, tinged buffy ; the under tail coverts pale rufous ; 

 the quills and rectrices just beginning to appear from the sheaths, 

 so that the wing is outwardly bordered by a white bar (coverts) which 

 is inwardly edged black. 



This is a huge ploverlike bird with a very heavy, somewhat re- 

 curved bill. It has the upperparts sandy brown; the wings sandy 

 brown with the shoulder area blackish brown and a white patch at 

 the center of the outer primaries ; a streak above the white eyebrow, 

 the ear coverts, and a mustachial streak black; the underparts white 

 with a broad, indistinct brownish breast band.

On the Chiang Mai plain the collared pratincole appeared rather 

 irregularly and in small numbers between March 23 (1929) and June 

 27 (1931) (one seen, February 16, 1937) but was unknown at other 

 seasons. At Ban Mae Chai I collected a male from a flock. Other- 

 wise the species is unrecorded from our provinces, although it might 

 be expected to occur on occasion almost anywhere in the lowlands. 



This swallow-plover avoids the rivers and keeps to the fields 

 (whether fallow or plowed) and moist areas overgrown with low 

 grass. Here it may be seen in loose flocks : some individuals feed on 

 the ground, making short running dashes after their insect prey; 

 others wheel through the air with graceful flight, somewhat resembling
