Catalogue of the Birds of Illinois. 
18. C. ossifragus , Wils. — S. and E. A species supposed to be peculiar 
to the vicinity of the sea-coast, but possibly ascending the Mississippi and its 
larger affluents as far as Southern Illinois (see note on page 183). 
Genus Perisoreus, Bonaparte. 
19. P. canadensis (Linn.) Bp. Canada Jay. — N. Obtained by Dr. Hoy, near 
Racine, Wisconsin, in the winter of 1859 (Nelson, p. 113). Possibly a very rare 
winter visitant to the extreme northern portion of the state. 
Genus Aphelocoma, Cabanis. 
20. A. floridana (Bartr.) Caban. Florida Jay. — S. E. The Florida Jay is 
considered to be peculiar to a limited portion of the peninsula of Florida; but we 
see no reason to suppose that its range is thus restricted. The laws of geo- 
graphical distribution most emphatically suggest a wider distribution. Indeed, 
it has been recorded from Kentucky by certain authors; and, though the evi- 
dence upon which this record was based appears insufficient, it seems extremely 
probable that, like Peuccea cestivalis, it may eventually be discovered far beyond 
its previously known range. It is a species which inhabits thickets of bushes 
or low trees, and should be carefully looked for in such localities, which, in the 
form of “oak barrens ” and the scrubby growth of crab-apple, wild plum, &c., 
abound in the southern part of Illinois. 
TYRANNID JE. — Tyrant Flycatchers. 
Genus Tyrannus, Cuvier. 
21. T. vociferans , Swains. Cassin’s Kingbird. — S. W. A bird of the 
Great Plains, ranging as far north as Cheyenne, Wyoming. May occur 
in the semi-prairie districts of Western Illinois. 
22. T. verticalis, Say. Western Kingbird. — W. A great wanderer, hav- 
ing been obtained at many eastern localities, as Iowa (Allen, Mem. Boston 
Soc., I., 1868, 498); New Jersey (Turnbull, Birds E. Penn. & N. J., 1869, 41); 
Maine (Bryant, Pr. Boston Soc., 1865, 96); and District of Columbia (Jouy, 
Field and Forest, April, 1877, p. 178). 
Genus Milvulus, Swainson. 
23. M. tyrannus (Linn.) Bp. Fork- tailed Flycatcher.— S. A tropical species, 
but a great wanderer, having been obtained in several of the eastern United 
States; e. g. Henderson, Kentucky, New Jersey, and Mississippi (Audubon). 
24. M.forficatus (Gmel.) Sw. Scissor-tailed Flycatcher. — S. W. Essen- 
tially a southern species (but chiefly Mexican), and, like the preceding, a great 
wanderer. Common in the semi-prairie districts from Texas to the Indian 
territory, where known as the “ Scissor-tail,” and “ Bird of Paradise.” Has 
occurred at Fort Riley, Kansas (Snow, Catal. Birds Kansas, 1873, 3), and at 
Trenton, New Jersey (Abbott, Am. Nat. 1872, 367). 
CAPRIMULGIDiE. — Goatsuckers. 
Genus Phal/enoptilus, Ridgway. 
25. P. nuttalli (Aud.) Ridgw. Poor-will. — W. Breeds as far east as 
Eastern Kansas (Allen, Bull. Mus. Comp. Zool., II., 1872, 179; Snow, Catal. 
Birds Kansas, 1872-3, 3). If occurring in Illinois, would be found on the dryer 
prairies.
