Tue habits of this beautiful species, like those of the preceding, 
are not consistent with the shape and construction of its bill; the for- 
mer would rank it with the Titmouse, or with the Creepers; the latter 
is decisively that of the Warbler. The first opportunity I had of 
examining a living specimen of this bird, was in the southern parts 
of Georgia, in the month of February. Its notes, which were pretty 
* As with many others, there has been some confusion in the syaonyines of this 
species, and it has been described under different names by the same authors. 
That of 'flavicollis, adopted by our author, is characteristic of the markings ; whereas 
vensilis, of Latham and Vieillot, is applicable to the whole group ; and perhaps re- 
storing Wilson’s name will create less confusion than taking one less known. The 
genus Sylvicolo, with the sub-genus Vermivora, have been used by Mr. Swainson 
to designate almost all those birds in North America, which will represent the Eu- 
ropean Sylviane, or Warblers. They are generally of a stronger make; the bill, 
hongt slender, is more conical, and the wings have the first and second quills of 
nearly equal length. The general dress is chaste and unobtrusive ; but, at the same 
time, we have exceptions, showing great brilliancy and beauty of coloring. Their 
habits are precisely the same with our Warblers. They frequent woods and thick- 
ets. They are in constant motion, creeping and ey dal about the branches, and 
inspecting the crevices in the bark, or under sides of the leaves, in search of insects 
en their duties of incubation are over, they become less retired, and, with their 
broods, assemble.in the gardens and cultivated grounds, where they find sustenance 
in the various fruits andl berion, The notes of all are sprightly and pleasant ; and 
a few possess a melody hardly inferior to the best songsters of Europe. 
Mr. Audubon has figured the following birds, which appear to rank under this 
enus, as hitherto undescribed :— Sylvia Rathbonia, Aud., male and female, plate 
xv. He met with this species only once ; it is entirely of a bright yellow color, 
about four and a half inches in length. The bill appears more bent than in the 
typical species. Sylvia Roscoe, Aud. plate xxiv. male; looking more like a 
ichas, shot on the Mississippi, the only one seen. The colors of the wy per parts 
are dark olive, a slender white streak over each eye, and a broad black band from 
the eye downwards ; the under parts, yellow. Sylvia Childrenii, Aud. plate xxxv. 3, 
killed | in the state of Louisiana; only two specimens were met with. General color 
of the plumage, yellowish green ; length, about four inches and three quarters. 
We cannot but regret the want of specimens of these interesting and rare species. 
Their authority will rest upon Mr. Audubon’s plates. It is impossible, from them 
alone, to say, with precision, that they belong to this genus ; and they are placed 
in it provisionally, with the view of making the list as complete as possible, and 
to pela them out to others who may have the opportunity of examining them.
