CHAKADEITJS. 



Geographi- 

 eal distribu- 

 tion. 



Young in 

 first plu- 

 mage. 



It was first discovered in Nepal, and probably ranges through the Eastern Himalayas 

 to the valley of the Yang-tze-kiang, whence it extends to all the Japanese islands. 



It appears to be nearest allied to C. minor, from which it differs only in being larger, 

 in having a more graduated tail, and when adult in having the shafts of all the primaries 

 brown. Young in first plumage, which may be recognized by the buff margins of the 

 feathers of the upper parts, have the shaft of the first primary white, as in C. minor 



Like the Little Ringed Plover, it is more partial to the banks of rivers and lakes than 

 to the sea-shore, and, like that species, the variation in colour attributable to differences of 

 sex or season are very slight. The fact that in young in first plumage the black is replaced 

 by brown probably denotes that its ancestors were shore birds.
