170 BLAGK-TEROATEB GREEN WABBLEB. 



are almost entirely white, having on the outer web only a faint black 

 stripe, which is broader at the tip, and towards the rump is almost 

 lost in the black shaft; the third tail feathers also have on the inner 

 webs a large white spot. Beak, feet, and iris, brown black. 



The form of this little bird is elegant, though the beak is rather 

 strong in proportion to the size of the bird; the feet are somewhat 

 feeble. The tail is almost evenly notched; the outer pair of feathers 

 are rather the shortest. Wings are tolerably pointed; the first and 

 fourth primaries are of equal length, the second and third only a 

 trifle longer; the second, third, and fourth, are near the tips of the 

 outer web very strongly notched. 



The whole length of the bird, from the forehead to the point of 

 the tail, five inches; length of the wing in repose two inches and six 

 lines; of the tail two inches; an inch of the tail uncovered by the 

 wings. Beak five lines; tarsus nine lines; middle toe three lines; 

 claws two lines; hinder toe three lines, and the very curved claw of 

 ditto two lines and a half." 



The bird has been preserved in spirits. 



Dendroica mre7is belongs to the group of Leaf Warblers. Its habits 

 are so well described by Audubon, that I take the liberty of tran- 

 scribing the following from his work upon the "Birds of America." 



"I have traced this species from Texas to Newfoundland, although 

 at considerable intervals, along our Atlantic coasts, it being of rare 

 occurrence, or wanting in some parts, while in others it is abundant: 

 but in no portion of the United States have I met with it so plentiful 

 as around Eastport, in Maine, where I saw it in the month of May. 

 Many remain all summer in that State, as well as in Massachussetts 

 and the northern parts of New York; and some are found at that 

 season even in the higher portions of Pennsylvania. On the coast of 

 Labrador it was not observed by me or any of my party, and it is 

 not mentioned by Dr. Richardson, as having been seen in the Fur 

 Countries. Its habits are intermediate between those of many of our 

 Warblers and the Vireos, the notes of which latter it in a great 

 measure assumes. 



It usually makes its appearance in Maryland and New Jersey about 

 the first week in May, when it is observed to be actively engaged in 

 searching for food, regardless, as it were, of the presence of man. 

 Its movements when proceeding northward are rapid, and it advances 

 through the woods solitarily, or nearly so, it being seldom that more 

 than two or three are found together at this time, or indeed during 

 the breeding-season, at which period each pair appropriates to itself 

 a certain extent of ground. Its retrograde march is also rapid, and
