skirt of my dress several times as if to jab it with her beak, uttering 

 a fierce hiss for so small a creature. She really looked almost fear- 

 some — a perfect little fury. She kept between me and the young 

 birds while the father tolled them to a place of safety. At one 

 moment she ran at me hissing ; the next simulated the helplessness 

 of a young bird calling for succor, cJich-cli-eh-eli, or zviet-et-et-ct. I 

 changed my position to a spot near one of the young birds. The 

 male immediately took the part of a helpless young bird, while the 

 female instantly began to draw the flock across the path into 

 another wood. 



Twenty-four hours later the parent birds were feeding the 

 young in the trees. The male bird had charge of a young bird he 

 was teaching to fly. Both young and old birds called te-tce-te-tee-te- 

 tee, constantly. The old birds had assumed the notes of the young, 

 immature birds. 



The young birds were similar to the old birds, black and white, 

 the black slightly brownish, the white a bit yellowish or dirty look- 

 ing. The breast was speckled with black, the rest of the under 

 parts white. 



The nest was built in a depression full of leaves, behind a flat 

 rock. The gray birch leaves were held in place by a fir branch. 

 Under this branch in the' midst of the leaves, the birds had hollowed 

 a space for a deeply cupped nest. The cavity was shaped on a 

 slant, the upper wall forming a partial roof. The nest was a mass 

 of leaves, with an interlining of pine needles; the lining proper con- 

 sisted of horsehair. There was not much horsehair on the side that 

 formed the roof. It looked not unlike a small-sized nest of an Oven- 

 bird. On the inside, the length was 2^ inches, width i^ inches, depth 

 2 inches. On the outside, length 3^ inches, width 2^ inches, depth 

 2^ inches. Thickness of wall at the top of nest, i inch; at the bot- 

 tom, ^ inch. (These measurements were taken after the young left 

 the nest.) 



The last migrating Black and White Warblers in 1908 passed 

 southward on the i3tli of September. In 1909, 1 saw the Black and 

 White Warbler migrating Sept. 19th, in a company of Blue-headed
