MIGRATION. 



Certain phases of bird migration in New Hampshire are per- 

 haps of sufficient interest to warrant a few remarks in addition 

 to the notes given under the several species in the following 

 list. 



The coastwise migration of many of the smaller land birds is 

 worthy of much further study. Mrs. Celia Thaxter ('70, p. 

 581, et seq.) has given a short account, written in her charming

 Isles of Shoals. Here, at some six or seven miles off the coast

 to the mainland. Yellow-birds \Dendroica cestiva\ and king- 

 birds occasionally build here, but very rarely By the 



23rd of April come the first swallows, and flocks of mar-

 the tiny ruby-crowned wren \_Regnlus calendula}, and troops of 

 many other kinds of birds ; kingfishers that perch on stranded 

 kellocks, little nuthatches that peck among the shingles for hid- 

 den spiders All these tarry only awhile in their passage 



to the mainland Now and then a bobolink pays us a fly- 

 ing visit, and, tilting on a blackberry spray, pours out his in- 

 toxicating song ; some morning is heard the fairy bugling of 

 an oriole ; a scarlet tanager honors the place with half a day's 

 sojourn." These migrants may very likely be. cutting across 

 the curve of the coast to strike the Maine shores farther north, 

 and in fall there seems to be a somewhat similar movement in
