No. 216c Sahuaro Screech Owl A. O. U. No. 373L Otus asio gilmani Swarth. Synonyms.—Arizona Screech Owl. Formerly called Mexican Screech Owl. Description.—Adult: Somewhat similar to 0. a. bendirei, but much paler and grayer,—ashy gray tone sustained nearly throughout; under plumage heavily and finely mottled gray (with customary'black streaks); the upper plumage slightly rufes- cent; the disc-feathers of throat somewhat modified, those of the middle broadly black-ribbed, those of the side with rib suppressed distally, and sharply cross-barred instead. Length of adults: (); male: wing (); tail (); bill from cere (.51); female: wing (); tail (); bill (-53)- Remarks.—This form represents the extreme in another line of divergence from 0. a. ncevius, viz., the maxwellice-aikeni-gilmani group. There is a hiatus between its range and that of bendirei (or qnercinus Grinnell), and there is no suspicion of inter- grading between them. This also is known as a monochromatic form, i. e., it has no recognized rufescent phase; but a specimen taken by Dr. Cooper at Ft. Mohave on the Colorado River in 1861 (Mus. Vert. Zool. No. 4395) is decidedly warm in tone throughout, possibly the effect of fading. IIO4. Please note that these images are extracted from scanned page images that may have been d
