heard it sing with a low warbling note which was very 

 pleasant. 



90. Melospiza Lincolnii, Baird. — Lincoln's Sparrow. 

 Very rare. Mr. S. Jillson has taken it at Hudson on one 

 or two occasions in spring. 



91. Passerella iliaca, Swain. — Fox-colored Sparrow. 

 Common during the migrations. Have taken it in spring 

 from March 14th to April 13th. While with us at this 

 season it has a most pleasing .song. Passes us in the 

 autumn in October. 



92. Passer domestica, Leach. — European House 

 Sparrow. Introduced, but common already in localities ; 

 will soon, without doubt, be generally distributed. 



93. Enspiza Americana, Box. — Black-throated Bunt- 

 ing. Very rare summer visitor, or straggler, from the 

 south. My young friend, John Thaxter, shot a specimen 

 June 26, 1867; it was a female, and, as I should judge, 

 from the peculiar appearance of the ovaries and oviduct, 

 had laid her eggs ; while the bare and swollen appearance 

 of her breast seemed to indicate that she was incubating. 

 Mr. Samuels speaks of two instances of its capture.* 



94. Guiraca Ludoviciana, Swatn. — Rose-hreasted 

 Grosbeak. Common summer resident. Breeds, nesting in 

 trees and bushes. Amves from May 8th to 2 2d ; leaves 

 early in September. Frequents open woods. 



The Blue Grosbeak (Guiraca coerulea, Swain.) perhaps 

 rarely occurs ; it has been taken in Calais, Maine, " where 

 it is very uncertain, but was common in the spring of 

 1861." t 



95. Cyanospiza cyanea, Baird. — Indigo-Bird. 

 Common summer resident. Breeds, nesting in low bushes. 

 Arrives from May 10th to 22d; in autumn found in flocks
