Birds -- North America
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.
