GEOKICHLA. . 551 
mm. Legs, feet, and claws flesh-color. Wing, 108 to 102; tail, 61 to 
53; culmen, 19.5 to 18; tarsus, 29 to 28. The adult plumage of the 
sexes appears to be alike, nor is it known that any important change takes 
place by abrasion. 
Young in first plumage appear to have the whole of the upper parts 
dull chestnut, each feather having a pale shaft and obscure pale center; 
the white bars on the wings are suffused with chestnut, and the black on 
the under parts is confined to two moustachial lines on the cheeks, the 
rest being dull chestnut. ‘This plumage is immediately molted to the 
adult plumage in the first autumn, except that certain birds, which I take 
to be females, have the slate-gray of the upper parts replaced by dark 
olive-brown.” (Seebohm.)
