The Bay-sreastep WazsLER, Sylvia castanea, 
comes to us about the middle of May, and remains 
a few days. In its appearance and manners it 
Strongly resembles the preceding. While here, it is 
busily engaged in searching for insects, along the 
hedges and in the highest trees. Where it goes 
when it leaves us, is not yet distinctly known. 
Audubon says that he has often seen them in Loui- 
siana, in the month of June, which would indicate, 
that, unlike the warblers in general, they remain and 
breed in the southern states. But if it is so, their 
nest has not yet been found. 
The Buack-pote WansLEn, Sylvia striata, is not 
uncommon in the latter part of May, when it is seen 
in the orchards in pursuit of cankerworms and other 
food. Its note is a low clinking sound, that can 
hardly be called a song. Audubon was fortunate 
enough to find its nest at Labrador. It was built on 
a fir tree, about three feet from the ground. There is 
something curious in the manner in which this and 
other warblers, in their migration, skip over some 
parts of the country. 
The Pine Warster, Sylvia pinus, is a summer 
resident in the State, but not much known, because 
it resides in deep, evergreen forests, where it explores 
the bark and buds of trees in search of the insects : 
which infest them. Nuttall describes a nest of this 
species, which he found at Mount Auburn, on á tree, 
forty feet above the ground. The eggs were white,
