The youug bird killed iu March is just completing its 

 moult, but has some whitish edgings to the scapulars and 

 innermost secondaries. The other young bird shot in April 

 is also in full moult, and still has the old primaries. The 

 throat and chest are much suffused with ashy.

In some of the adult birds there are slight remains of 

 dusky streaks on the throat and breast. The female procured 

 in October is in worn plumage and appears to have been 

 breeding. The examples killed in March are immature and 

 have remains of rufous edgings on the feathers of the upper 

 surface, although the moult is nearly completed (with the 

 exception of the long primaries), shewing that these evidences 

 of immaturity last a little time after the moult into the first 

 mature plumage : the rufous edgings are still to be seen in 

 April specimens, nor is that killed in May entirely devoid of 

 them.
