bushes, about three and one-half feet from the ground, 

 and was a bulky thick-walled structure of grasses, out- 

 side as large as a Robin's nest, with a proportionally 

 small cavity. The eggs of this species are not distin- 

 guishable from those of the White-throat. The song 

 is however quite different. The irregularity of the 

 migration is witnessed by the great abundance of the 

 bird some seasons in particular localities, and its rarity 

 or entire absence at other times and places, render- 

 ing it difficult to speak of these matters with desirable 

 precision. It has occurred in the vicinity of Portland 

 "in almost unprecedented numbers," says Mr. N. C. 

 Brown (Bull. Nutt. Club, i, 1876, p. 95). Mr. Allen 

 has seen it in Massachusetts as late as June 6th. In 

 Connecticut, according to Mr. Merriam, it has been 

 found from October to December, and from March 

 20th to the middle of May.
