30 LAND-BIRDS AND GAME-BIRDS 



or five, and like those of the Robin, but smaller, measuring 

 1-10 l-OOX'70 of an inch. Those of the first set are usually 

 laid near Boston in the last week of May those Of the second, 

 if any, in the early part of July. 



(c). The Wood Thrushes probably represent the highest 

 type among birds ; excelling all others, except their immediate 

 relatives, in details of structure, in the quiet beauty of their 

 coloration, and in the refinement of their habits ; and they are 

 certainly to be ranked among the finest singers of the world. 



Though possessed of comparatively little power of flight, 

 yet the Wood Thrushes, like most other birds, migrate very 

 far (more than a thousand miles), about the tenth of May 

 reaching Massachusetts, to the northward of which, in New 

 England, they rarely go. But they are common in southern 

 New England from the time of their arrival until that of their 

 departure in September or October ; during the summer-months 

 inhabiting groves and woods of various kinds, oftenest, per- 

 haps, those which are swampy or of low growth. In such 

 places they build their nest and rear their young, and there 

 obtain the necessary supply of insect-food, either from the 

 ground, over which they can run with some rapidity, or from 

 the bushes and trees, among which they move with such leisure 

 and dignified grace as would become a prince. The most con-

 apparent modesty and the actual love of privacy or solitude, 

 which they generally, though not invariably possess. These 

 lend a charm to the study of their habits and their music, but 

 they also cause difficulty in acquiring an intimacy with them, 

 a difficulty, however, which can be overcome. Though the 

 Wood Thrushes are so fond of individuality and retirement, 

 that they are never properly gregarious, and that they prefer 

 retreats in woodland, where they are, unlikely to be disturbed, 

 to all other suitable haunts, yet they often build their nests in 

 quite conspicuous places, and frequent the immediate neigh- 

 borhood of man. Nor are they then more shy than under 

 other circumstances, in fact, the female is generally prompted 

 by instinctive motherliness to sit as bravely on her nest, when
