 to the sides of the neck, where it runs into a close patch of black streaks continued along 

 the breast and sides to the root of the tail. Outer two tail-feathers with an oblique patch 

 on the inner web near the end ; the others edged internally with white. Female similar,

Tlie autumnal dress of young birds is yery different from that of spring. 

 The upper jiarts are light olive-green, obsoletely streaked with brown ; be- 

 neath greenish-yellow, obsoletely streaked on the breast and sides, the under 

 tail-coyerts pure white, a yellowish ring round the eye, and a superciliary 

 one of the same color. In this dress it is scarcely possible to distinguish it 

 from the immature B. castanea. The ditl'erences, as far as tangible, will be 

 found detailed under the head of the latter species. 



The young bird in its first dress is also quite different, again, from the 

 autumnal-j)lumaged birds. The upper parts are hoary-grayish, the lower 

 \vliite ; each feather of the whole body, except lower tail-coyerts, \\ith a ter- 

 ininiil bar or transverse spot of blackish, those on the upper parts approach-
