20 NORTH AMERICAK WARBLERS. 



The full records are: Alligator Reef, March 4, 1889; Sombrero Key, 

 March 7, 1887, March 10, 1888, and March 3 and 11, 1889. 



The average date of earliest arrival at Raleigh, N. C, from 1885 to 

 1899, inclusive, is March 27, with extremes of March 19, 1891, and 

 April 1, 1885. At Statesville, directl}^ west of Raleigh and but little 

 higher, the average date of earliest arrival in 1885, 1887, and 1888 is 

 also ^larch 27. Corresponding records have been received from 

 Chapel Hill, Greensboro, and the southern part of Bertie Count}^, 

 while near Asheville, N. C, in the mountains, at 2,000 feet, the average 

 date of arrival for the five years 1890 to 1894 is April 3. 



The statements of writers on the migration of this species through 

 Florida, etc., may be thus summarized: Tarpon Springs, first arrival 

 during the last part of March; Palatka, first arrival March 13, 1885 — 

 species common March 21; first arrival at Gainesville, March 15, 1887; 

 at Pensacola, March 21, 1885; at Perdido Light, March 22, 1885; at 

 Shelby, Ala., March 18, 1898; at Coosada, Ala., March 13, 1878; near 

 Beaufort, S. C, April 6, 1885, April 5, 1889, and March 29, 1887; 

 and at Savannah, Ga., April 1, 1891. The average of nine years at 

 Kirkwood, Ga., is April 2, with extremes of March 21, 1899, and 

 April 10, 1895. Farther north some average dates of arrival are 

 recorded as follows: French Creek, W. Va., April 13; Washington, 

 April 13: Beaver, Pa., April 22; Philadelphia, April 27; Englewood, 

 N. J., April 26; southeastern New York, April 28; central Connecti- 

 cut, April 28; eastern Massachusetts, April 28; southern New Hamp- 

 shire, May 1; southern Maine, Ma}^ 3; Montreal, Ma}^ 9; Quebec, 

 Ma}^ 12; St. John, New Brunswick, May 11; North River, Prince 

 Edward Island, May 17. 



The Mississippi Valley furnishes two extended and excellent sets of 

 records of first arrival of this species — at Helena, Ark., and Eubank, 

 Ka\ At Helena the average for the six years from 1896 to 1901 is 

 March 31, with extremes of March 21, 1897, and April 7, 1901. The 

 record of eight years at Eubank, Ky., is remarkabl}^ regular for a 

 single species at a single place: April 3, 1887, April 1, 1888, April 4, 

 1889, April 3, 1890, April 3, 1892, April 2, 1893, April 3, 1894, April 

 6, 1895, average, April 3. No records south of Helena harmonize 

 with these. If the birds alight on the Gulf coast and then move 

 northward, they should be abundant at New Orleans and should be 

 seen there on the average about March 20, and sometimes several days 

 earlier. The facts are that the}^ are not common at any place in south- 

 ern Louisiana and southern Mississippi, and the dates of arrival are 

 late: Near New Orleans, April 8, 1898, March 31, 1899, March 25, 

 1900; Shell Mound, Miss., April 7, 1892; Rodney, Miss., April 2, 

 1889. A possible explanation of this may be that the black and white 

 warbler prefers forests growing on high, dry land, and consequently 

 the early, strong-flying individuals, after crossing the Gulf of Mexico,
