YELLOW-TKROATED FLYCATCHER.

note, which it repeats with some little variation, every ten or 
twelve seconds, like preed , preed , &c. It is often heard in 
company with the Red-eyed Flycatcher ( Muscicapa olivacea) 
or Whip-tom-ke!ly of Jamaica; the loud energetic notes of 
the latter, mingling with the soft languid warble of the former, 
producing an agreeable effect, particularly during the burning 
heat of noon, when almost every other songster but these two 
is silent. Those who loiter through the shades of our magni- 
ficent forests at that hour, will easily recognize both species. 
It arrives from the south early in May ; and returns again 
with its young about the middle of September. Its nest, 
which is sometimes fixed on the upper side of a limb, some- 
times on a horizontal branch among the twigs, generally on a 
tree, is composed outwardly of thin strips of the bark of grape 
vines, moss, lichens, &c. and lined with fine fibres of such like 
substances ; the eggs, usually four, are white, thinly dotted 
Bonaparte and Swainson of species which were not at first contemplated as 
belonging to it. 
The group is peculiar to both continents of America, — they inhabit woods, 
feed on insects and berries, and in their manner have considerable alliance to 
the Warblers and Flycatchers. By Mr Swainson they are placed among the 
Ampelidce, or berry eaters, but with a mark of uncertainty whether they should 
stand here or at the extremity of some other family. The Arctic Expedition 
has added a new species much allied to V. olivaceus. Mr Swainson has 
dedicated it to the venerable naturalist Bartram, the intimate friend of Wilson, 
and mentions, that, on comparing seventeen species, Vireo Bartramii was 
•much smaller, the colours rather brighter, the wings considerably shorter and 
more rounded, and the first quill always shorter than the fifth, — that 
V. olivaceus is confined to North America, while V. Bartramii extends to 
Brazil. The species of the Arctic Expedition were procured by Mr David 
Douglas on the banks of the Columbia. Mr Swainson also met with the 
species in the Brazils ; and, from specimens sent to us by that gentleman, I 
have no hesitation in considering them distinct, and of at once recognizing the 
differences he has pointed out. 
Mr Audubon has figured another species which will rank as an addition to 
this genus, and, if proved new, will stand as Vireo Vigorsii ; he has only met 
with a single individual in Pennsylvania, and enters into no description of its 
history, or distinctions from other allied birds. — Ed.
