Warbler, Black-Throated Blue 



It treats a tree as a staircase, hopping up a branch at 

 a time, often stopping on the landings to follow the limbs 

 out to their tips, and then, instead of vaulting into the 

 air or dropping off in somersaults as do many of its acro- 

 batic relatives, stops still, turns its head over and looks 

 up before going on up the next stair.

WARBLER, BLACK-THROATED GREEN 



This is one of the most welcome birds to the would-be 

 ornithologist, because it is so easily recognized. The 

 black inverted V of its under parts (A), the yellow cheeks 

 and large areas of white on the tail, are unmistakable.

The "black-throated greens" are, to me, with perhaps 

 the exception of the pine warblers, the most attractive 

 members of their family, on account, I think, of their 

 pleasing, familiar, and oft-repeated songs, . . . which 

 form so fitting an accompaniment to the whispering of 

 the pines.
