at one while she was sitting on her nest, and she almost 

 permitted me to touch her before she flew oiF. 



By the first week in September, the old birds and young, 

 apparently in a group by themselves, leave for the South, 

 and winter in Panama and the Bahamas.

Male. — Crown, nape, and upper half of the head black ; the lower half, including 

 the ear coverts, white, the separating line passing through the middle of the eye ; 

 rest of upper parts grayish-ash, tinged with brown, and conspicuously streaked with 

 black; wing and tail feathers brown, edged externally (except the inner tail feathers) 

 with dull olive-green ; two conspicuous bars of white on the wing coverts, the ter-

 throat from the chin 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, except that the upper parts are olivaceous, and, even on the
