brownish white ! The nest is also found sometimes suspended 

 to the extremity of a bundle of ivy, which escapes from the 

 branches of a tree, or from a wall ; but it is always con- 

 cealed in the foliage. When the female hatches, the male 

 sings a short song, not without agreeableness ; he also 

 relieves her in the middle of the day from the cares of 

 incubation. 



This species is extended throughout all Europe, from 

 Sweden to Italy. It is also found in Asia, as far as Bengal, 

 and even in the United States of America, where it principally 

 frequents the northern provinces, not advancing southwards, 

 except in the autumnal season of the year. 



M. Vieillot says that there are two races of this bird, one, 

 which has been described, and another which he calls crested 

 Avren, with mustachios ; the cry of the latter, according to 

 this naturalist, is stronger than that of the other. It remains 

 at the summit of the highest trees, and is seen only in couples, 

 male and female. It is also more distrustful and approached 

 with greater difficulty ; neither is it met with precisely at the 

 same period as the other. 



The Yellow Wren Warbler (M. Trochilus, et Pouillo of 

 Buifon) is a very small bird, spread universally throughout 

 Europe, as far north as Sweden. It is with us a bird of 

 passage, coming in spring and departing in autumn, pro- 

 ceeding doubtless towards more southern climates. It is 

 known by various names in the different countries which it 

 inhabits, derived either from its habits or its cry, which is 

 nothing but the frequent repetition of the monosyllables tuit,

During the fine season, this bird remains in the woods, 

 where it lives on small insects, such as gnats, &c. It fixes 

 its nest in tufted plants or bushes. This nest is composed 

 with much art and care. Externally it is constructed of 

 moss, and internally furnished with horsehair and wool. It 

 has the form of a little ball, and no other aperture than a
