Autumnal plumage : young male. Above similar to adult, but darker,

20. Mniotilta varia. 



" First plumage. Similar in general appearance to the adult female, but 

 markings, especially the two stripes of the pileum and the streaks beneath, 

 much less sharply defined ; the streaks of the breast indistinct grayish-
