tail coverts white, more or less strongly washed with buff. The adult

The bluethroat has been taken only at Sala Mae Tha and Chiang 

 Mai ; at the latter place it is a regular winter visitor in small numbers 

 at suitable localities and has been recorded between October 24 (1931) 

 and March 28 (1931). 



I found this species only at the edges of drying nong, feeding on the 

 ground at muddy places in company with stints and wagtails and, at 

 the least alarm, vanishing into the dense cover of rushes and sedges, 

 where it was as well concealed as any small rail. It seems to be a 

 solitary bird, although some numbers may occur in close proximity as 

 favorable areas become reduced by drought and the harvesting of 

 marsh vegetation. 



A male had the irides brown ; the bill black, yellow at the base ; the 

 interior of the mouth yellow; the feet and toes brown; the soles 

 yellowish ; the claws black. 



The adult male, in full plumage, has the entire upperparts grayish 

 brown, the feathers of the forehead and crown with blackish centers, 

 those of the rump and upper tail coverts sometimes partly rufous ; the 

 wings grayish brown, the greater coverts narrowly tipped with pale 

 rufous; the central pair of rectrices wholly blackish brown, the re- 

 mainder similar but with the basal half rufous (conspicuous in flight) ; 

 a narrow white supercilium ; the chin and upper throat shining bright 

 blue ; the center of the lower throat and the upper breast covered by a 

 large patch of rufous, narrowly bordered by shining bright blue; a 

 narrow black breast band succeeding the blue border and this followed 

 by a narrow white band and a broad band of rufous; the remaining 

 underparts white, washed with buff, especially along the flanks and 

 on the under tail coverts. The adult female differs chiefly in having a
