SYLVICOLID^E — THE WARBLERS. 309 



Audubon states that in tlieir migrations they move from busli to bush by 

 day, and frequently continue their march by night. Their flight at all times 

 is short and irregular. He also states that when on the ground they squat,, 

 jerk their tails, spring on their legs, and are ever in a state of great activ- 

 ity. Although the existence of this bird north of Pennsylvania is generally 

 disputed, I have no do\d.)t tliat it has always been, and still is, a constant 

 visitor of Massachusetts, and has been found to within a score of miles of 

 the New Hampshire line. Among my notes I find that a nest was found 

 in Brookline, in 1852, by Mr. Theodore Lyman ; in Dan vers, by Mr. Byron 

 Goodale ; in Lynn, by Messrs. Vickary and Welch ; and in many other parts 

 of tlie State. It certainly breeds as far south as Georgia on the coast, and 

 in Louisiana and Texas in the southwest. On the Pacific coast it is replaced 

 by the long-tailed variety, longicauda. 



A nest of tliis species from Concord, Mass., obtained by Mr. P>. P. Mann, 

 and now in the collection of the Boston Natural History Society, has a 

 diameter of four inches and a height of three and a half. The cavity has a 

 depth of two and a quarter inches, and is two and a half wide. This is built 

 upon a base of coarse skeleton leaves, and is made of coarse sedges, dried 

 grasses, and stems of plants, and lined with long, dry, and wiry stems of 

 plants, resembling pine-needles. Another from Ponifret, Conn., oljtained by 

 Mr. Sessions, is a much larger nest, measuring five inches in diameter and 

 three and three quarters in height. The cup is two and a half inches deep 

 by three in widtli. It is made of an interweaving of leaves, bark of the 

 grapevine, and stems of plants, and is lined with fine, long wiry stems and 

 pine-needles. 



Their eggs are of a slightly rounded oval shape, vary in length from .85 

 to .95 of an inch, and in breadth from .65 to .70. They have a white ground 

 with a very slight tinge of yellow, and are marked with reddish -brown and 

 a few fainter purplish and lilac spots.
