*631. ViREO NOVEBORACENSis fGmel.). Whitc-cyed Vireo. 



Muscicapa noveboracensis. Muscicapa cantairix. 



Geog. Dist. — Eastern United States; north to Massachusetts, 

 New York (occasionally further north), to the Great Lakes, 

 southern Wisconsin, southern Minnesota; west to eastern Ne- 

 braska, Kansas, Oklahoma and Texas (except Rio Grande Val- 

 ley) ; breeding from northern Florida and Texas northward, and 

 wintering from the South Atlantic and Gulf States southward 

 through eastern Mexico to Guatemala. 



In Missouri a common and generally distributed summer resi- 

 dent, rarer westward and most abundant in bottom land and 

 along water courses throughout the different regions. In the 

 southeast the first White-eyes return to their breeding grounds 

 in the first week of April (April 2, 1896). In the vicinity of St. 

 Louis the earliest date is April 11, 1896, but commonly the dates 

 of "firsts" fall between April 14 and 18, exceptionally as late 

 as April 24, and the bulk is always back in the last days of April 

 in the western as well as the eastern part of central Missouri 

 (Independence, April 29, 1900; April 30, 1899, Tindall). At 

 the northern border Mr. Currier's dates at Keokuk vary between 

 May 5, 1896, and May 12, 1898. The return movement south- 

 ward takes place in the middle of September, when a decrease 

 is noticeable after the species has been quite conspicuous as a 

 songster during the first half of September. A few keep up sing- 

 ing and are occasionally heard till the end of the month (Sep- 

 tember 28, 1895, September 29, 1887). The last were noticed 

 as late as October 14, 1885, but they are always scarce after 

 September 26 to September 29, even in southern Missouri.
