to my house, in company with a little band of Warblers which may 

 have belonged to the same species."^ Mr. E. P. Bickuell observes:^ 

 "A female was taken [at Riverdale, on the Hudson] on October 9, 

 1876, and a second specimen seen on the 29th of the same month. 

 The former bird was shot while gleaning among the withering blos- 

 soms of a patch of golden-rods (Solidago), while the latter was hop- 

 ping about in a clump of leafless briers and shrubbery quite unsuspi- 

 ciously, allowing an approach of a few feet." 



Dmensions.— Measurements of No. 667 ^, Highland Falls, N. Y., 

 May 13, 1875, E. A. M. : length, 469; stretch, 7-25; wing, 2-22; tail, 

 1-85; bill from nostril, -30; tarsus, -69. 



27. Helminthophaga peregrina, (Wilson). Tennessee War- 

 bler. A rather rare migrant; sometimes abundant in autumn. In 

 spring a few are seen, generally in company with H. rujicapilla, dis- 

 porting themselves among the fruit blossoms. In autumn they are 

 sometimes found abundantly, along the river banks, in the willow 

 trees. I found large flocks in the willow swamps, on lona Island, 

 and on Consook Island, in September, 1876. 



Dimensions. — Average measurements of four specimens : length, 

 5-00; stretch, 7-68; wing, 2-63; tail, 1-69; bill from nostril, -32; tar- 

 sus, -65. 



28. DendroBca sestiva, (-BoddcerO- Yellow Warbler ; Summer 

 Yellowbird. a summer resident; not very abundant ; breeds. Ar- 

 rives early in May (12, 1875; 12, 1876; 17, 1877; 9, 1878), and remains 

 till autumn (September 3, 1874). 



Dimensions. — Average measurements of seven specimens : length, 

 5-10; stretch, 7-78; wing, 2-40; tail, 1-89; bill from nostril, -33; tar- 

 sus, -74. 



29. Dendroeca virens, (Gmelin). Black-throated Green War- 

 bler. A summer resident ; very abundant during its migrations ; a 

 few remain and breed. Arrives early in May (16, 1874; 11, 1875; 1, 

 1876; 12, 1877; 9, 1878; 7, 1879), and departs late in October (21, 

 1874; 28, 1876). It is found everywhere, in all kinds of woods; but 

 it is especially numerous in hemlocks growing among deciduous 

 trees. It is seen, in large companies, clinging to the tips of the 

 branches, exhibiting a fluttering of wings and incessant activity. Its 

 attitudes and notes remind one of the Titmice ; but it possesses a very 

 pleasant song, besides. Not rare in summer.

 length, 5-10; stretch, 7-72; wing, 2-46; tail, 1-99; bill from nostril, 

 •25; gape, -55; tarsus, 68; middle toe, '40; its claw, -16.
