on the agth of September, 1889, by Miss Cox and presented to the Provincial Museum. 
The larger species of this group, the 7yrannidae, are somewhat prone to wander but this is 
perhaps the most remarkable instance upon record, 
B. C. & H. No. 1x. 
AMERICAN BARN OWL, 
A. O. U. No. 365. Aluco pratincola (Bonap.). 
Description.—Adult; General color of upperparts ochraceous yellow; this lightly over- 
laid or mottled with gray, the typical mottled gray feathers having dusky centers and white 
tips; indistinct dusky bars on wing-quills and tail-feathers, clearest centrally; entire under- 
parts white, usually more or less washed with fulvous or tawny, and sparingly but sharp] 
speckled with dusky; facial disk white or whitish or tinged variously with oc’ caneinenete 
dark brown, or even claret; the edges of the disk rusty and dark brown on the tips of the 
feathers; bill light; feet light, nearly naked. The folded wing extends to or beyond the 
end of the tail. Nestlings are covered with fluffy white down. Length 14,00-18.00; wing 
12.25-1'4.00; tail 5.25-7.50; tarsus 2.25-3.25; bill along culmen 1.00-1.25. 
Recognition Marks.—Crow size; light colors. especially below; strongly marked facial 
disk; top-heavy appearance. 
Nesting.—Nest: in hollow trees or in crevices about towers, pigeon-houses, earth-banks, 
etc., lined scantily with sticks and trash. Eggs: 5-11, white, ovate. Av. size, 1.70 x 1.30. 
General Range.—United States, rarely to the northern border, and Ontario, southward 
through Mexico; normal northern limit of breeding range about latitude 41°. 
Occurrence in British Columbia.—A breeding female just captured (April, 1909) near 
Ladner’s Landing gives this southern species an established place upon our records. The 
bird is so exclusively nocturnal in its habits that our former oversight is not at all to be 
wondered at. 
Presumed Occurrence in Washington.—There are a number of Oregon records for 
this species and the record above noted makes a strong case for the Barn Owl as a bird of 
Washington. 
B. C. & H. No. x2. 
GREAT HORNED OWL. 
A. O. U. No. 375. Bubo virginianus (Gmel.). 
Description.—Similar to B. v. lagophonus (q. v. p. 478) but coloration averaging darker. 
Western examples probably represent merely individual variation of B. v. lagophonus or 
_ v. saturatus, since B. virginianus is strictly non-migratory. W. L. D.] 
General Range.—Eastern North America north to Labrador, west to eastern border 
of Great Plains, or, northerly, to Rocky Mountains (?). 
Occurrence in British Columbia.—T wo specimens taken at Chilliwack when laid along- 
side of an Eastern (Ontario) bird were absolutely indistinguishable, being very rufous and 
moderately light-colored.

RED-BELLIED HAWK, 
A. O. U. No. 330b. Buteo lineatus elegans (Cass.). 
Description.—Adult: Above rich chocolate-brown, fuscous and grayish brown, varied 
by rufous and ochraceous, especially on head and back, and by whitish on scapulars and 
inner quills; lesser wing-coverts extensively rufous, forming a red “shoulder”; wing-quills 
and greater coverts dusky-barred and white-spotted and -tipped, forming irregular bars; ends 
of primaries and tail principally blackish, the latter crossed by four or five narrow, white 
bands, and tipped with white; upper tail-coverts barred and tipped with white, affording 
occasional suggestion of white rump; four outer primaries deeply emarginate; underparts 
rich chestnut-rufous, of variable intensity, sometimes dark enough to obliterate all markings,

tibia, but under-pattern of tail always distinct. Cere and feet chrome-yellow; bill blackish; 
claws black. /mmature: Different: dark brown or fuscous above, only traces of rufous on 
wing-coverts, etc.; spotting of quills ochraceous; tail dusky, with seven or eight grayish 
bars which become more ochraceous and gradually obsolete basally; underparts not so 
richly colored as in adult, heavily streaked and meine with dark brown, Adult male, length: 
18.00-20.00; wing 11.50-13.50; tail 7.50-9.00. Adult female, length: 20.00-22.00; wing 12.00-
