§. XXXVIII. 
It appears from the works of Hernandez Fiso, J and several other writers, that many of the passenger birds of 
Pennsylvania, and other parts of the United-States, are also natives of Mexico, Brasil, and other southern parts of 
America, I shall here mention a few of these birds ; viz. the Vultur Aura, Psittacus pertinax, Oriolus phoeniceus, 
Oriolus Baltimore ? Gracula Quiscula, Gracula Barita, Pious principalis, Picus carolinus, or Carolina Woodpecker, 
Alcedo Alcyon ? Trochilus Colubris, Oolumba niigratoria, Columba carolinensis, Columba passerina, Turdus Poly- 
glottos, Turdus minor, Motacilla aurocapiUa, Ampelis Garrulus, Emberiza Oryzivora, Emberiza Ciris,* or Painted 
Bunting, Tanagra cyanea, Tanagra rubra, Muscicapa Tyrannus, or Fork-tail-Flycatcher, Motacilla Sialis, Muscicapa 
Kuticilla, Motacilla casrulea, Motacilla Guira,* or Guira Warbler, Platalea Ajaja,* or Roseate Spoon-Bill, Ardea 
canadensis, or Brown Crane, Ardea Nycticorax ? Tantalus Loculator,* or Wood-Ibis, Tantalus ruber,* or S.carlet 
Ibis, Charadi'ius Iliaticula,* or Ringed Plover, Charadrius Himantopus, or Long-Legged Plover, Haematopus 
Ostralegus, or Pied-Oyster-Catcher, Anas sponsa, and many others, § This circumstance renders it very probable, 
that many of our migratory birds pass their winters in these southern climates. How much is it to be wished, that 
some intelligent naturalists would furnish us with a list of the migratory birds of Mexico, Brasil, the West-India- 
Islands, &c. noting down, with care, the times of their disappearance from those countries, and the periods of 
their return to them. This would throw great light upon the difficult question which I am examining. Mean- 
while, I have little doubt it will be found, that several of these birds visit us about the time they leave the warm 
countries just mentioned. Some of the birds which I have mentioned, in the above list, are known to migrate from 
and to Mexico, Brasil, and the West-Indies. 
§. XXXIX. 
My learned and candid friend Mr, Pennant (whose name 1 never mention but with pleasure and with gratitude ; 
wrhose works have contributed much to my information, and whose example has stimulated me to the study of na- 
tural history) thinks there is the " greatest probability," that numbers of the birds of Kamtschatka are common to 
fsorth-America, " and that they pass there the seasons of migration." II I may observe, on the other hand, that 
it is likely that many of the North-American species pass into Asia and Europe, making between these continents 
ind the new-world regular migrations. I think (for I write from memory) that it is Professor Biseke who has lately 
jhown, that several of the North- American birds annually visit the neighbourhood of Mittau, in Courland. Among 
}ther8, I particularly recollect that this writer mentions the Loxia Cardinalis, or Cardinal Grosbeak. In the farther 
nvestigation of the subject of the migration of birds, we shall discover, that many species (many more than is 
renerally imagined) are common to the old and. to the new-world ; and that several species are occasionally passing 
nto countries which before they had not visited. I am not afraid, that genuine naturalists will suppose, that the 
•egularity of migration, which I have mentioned, between the two continents, is altogether imaginary. I certainly 
lo not carry my birds as far, in search of food, of resting places, and of better climes, as did Cotton Mather, 
)f New-England, who fancied that the Wild-Pigeons, on leaving us, repaired "to some undiscovered Satellite, 
iccorapanying the Earth at a near Distance,"^

^ In this list I have not given the English names of any of those birds which occur in the Tables. I have annexed the mark of doubt to a few which . 
■erhaps, are not entirely the same species in the United-States and in Southern America. Those which are designated with an asterisk are not known 
a Pennsylvania. Mr. Pennant (Arctic Zoology. You II. P. 107.) mentions the Motacilla Guira as a native of New- York. The Embenza Cms has 
ever (that I can learn) been seen farther north than Cape-Fear in North- Carolina, and not more than one mile from the salt water. The Spoon-BiU 
} sometimes (though rarely) seen about the mouth of Cape-Fear-River. They are common about St. Augustine, in East-Florida, and even as far north 
; 9 the Savanna-River. Mr. William Bartram.
