The rather peculiar, as well as very extensive, distribution of this " - 

 species may l)e fathered from the foregoiDg references, selected from the - 

 great number that have been recorded. The Pacific coast advices aTeJ-^J\( 

 not so remarkable as they would api)ear, did we not know that the, , ; 

 Eastern Province trends westward north of the United States, to Alaska, " , ' 

 where many characteristic Eastern birds were noticed by Mr. Ball and 7 ^ 'fi 

 Dr. Bannister. In view of this it is not surprising that individuals^^-. .^^ 

 straggle southward along that coast. But it is remarkable, that while ' 



the bird's continental breeding range is not south of Northern New'^/'*" i 

 England, it should also breed in the West Indies. Its wintering range ^j;»^ 

 appears almost anomalous. While some individuals are at that season 

 in subtropical and tropical America, others are wintering in the Middle 

 States, if not also in Southern New England. 



The Yellow-rump lays four to six eggs, measuring about 0.72 by 0.54 

 inches ; they are white, spotted chiefly in a wreath about the large eud, but 

 also sparingly over the entire surface, with various shades of brown, none, 

 however, quite reddish, but some nearly blackish, and with numerous 

 other shell-markings of neutral tint. A nest from the Yukon (June 7) 

 is rather rudely built of weed-stalks, grass-stems, and rootlets, and 

 warmly lined throughout with feathers. Another from the Arctic coast, 

 east of Anderson Eiver, is entirely composed of soft vegetable fibre, with 

 a few grass-stems for lining ; it was built in a pine-tree, about six feet 

 irom the ground. A third, from Nova Scotia, laid on the horizontal 

 fork of a tree, is composed chiefly of very slender, stiff rootlets and 

 similar hard stems, and is much flatter than either of the others.
