That these two very different plumages are entirely independent of age, sex, or season, and that they are purely individual, there can be no doubt; since in one nest there may often be found both red and gray young ones, while their parents may be either both red or both gray, the male red and the female gray, or vice versa. Occasionally specimens (such as No. 39,093, ♂, Neosho Falls, Kansas, April 13; parent of five eggs, and captured on the nest with a gray male) are exactly intermediate between these two plumages, it being difficult to decide which predominates; the combination is not only of the tints, but of the markings, of the two stages.
Habits. The habit of all the varieties of Scops asio in their different localities will be found after their zoölogical description.
Scops asio, var. floridana, Ridgway.
Scops asio, Allen, Bull. Mus. Comp. Zoöl. and other citations from Florida.
Char. Similar to var. asio, but much smaller, and the colors deeper. The gray stage very similar to that of var. asio, but the red phase very appreciably different, in there being a greater amount of rufous on the lower parts, the breast being nearly uniformly colored, and the rufous broken elsewhere into transverse broad bars, connected along the shaft. Wing, 5.50–6.00; tail, 2.75–3.10.
Hab. Florida and Lower Georgia.
This extreme southern form is much smaller than the more northern ones, being about the same in size as the var. enano (see p. 1374) of Middle America, and the S. atricapilla, Temm., of Tropical America generally. The colors, as may be expected, are also darker and richer.
In the collection of the Smithsonian Institution there are both red and gray birds from Florida; a red one (No. 5,857, Indian River; Dr. A. W. Wall) measures, wing, 5.50; tail, 2.70; culmen, .55; tarsus, 1.05; middle toe, .65; ear-tufts, .70. The colors are much darker than those of typical asio. The rufous of the neck, all around, shows obsolete darker transverse bars; the black border to the white scapular spots is restricted to the tip, as in the gray plumage; the inner webs of the ear-tufts are scarcely paler than the outer; the neck and face are deeper rufous, while the rufous of the lower parts is more general, and more in transverse rays; tibiæ and tarsi plain rufous; the middle of the abdomen and the anal region only are pure white.
