SYSTEMATIC SYNOPSIS. — PASSEBES — OSCINES. 
Grackles (Qiiiscalus) . (See any figs., beyond.) Excepting the arboreal orioles, the feet are 
large and strong, fitted for the nnore or less ten'estrial life which all the species lead, M'alking 
on the ground with ease instead of hopping like most FringiUidce. Xo specialties of wing or 
tail; former usually pointed, latter rounded, sometimes very large and fan-shaped. 
Among our moderate number of species are representatives of four of the subfamilies into 
which the Icteridce are conveniently and quite naturally divisible. In most of the genera black 
is the prevailing color, — either uniform and of intense metallic lustre, or contrasted with 
masses of red or yellow. In Stiirnella alone the pattern is niggled." In nearly all, the sexes 
are conspicuously dissimilar, the female being smaller and brownish or streaky in the iridescent 
black species, greenish and yellowish in the brilliantly colored ones. All are migratory in this 
country. Other details are best given under heads of the subfamilies. These groups, vnth 
their component genera, may be analyzed as follows by the salient features more likely to 
attract the attention of the student than less obvious technical characters : —

QuiscALiN^. Crow Blackbirds. Terrestrial and gregarious. Bill elongate, corvine. Feet stout. Color 
of cf entirely iridescent black ; $ brown or blackish. 
Bill shorter than head ; even tail shorter than wings Scolecophagus 104 
Bill not shorter than head ; graduated tail not shorter than wings Quiscalus 105 
22. Subfamily ACEL>EIN>E: Marsh Blackbirds. 
Gregarious, granivorous species, more or less completely terrestrial, and chiefly palustrine, 
not ordinarily conspicuous vocalists ; building rather rude, not pensile, nests, laying 4-6 spotted 
or curiously limned eggs. With the feet strong, fitted both for walking and for grasping 
swaying reeds ; the wings more or less pointed, equalling or exceeding the tail in length ; the 
bill conic-acute, shorter or little longer than the liead, its cutting edges more or less inflected. 
Four well-marked genera, the species of which abound in the United States, on plain and 
prairie, in marsh and meadow. In the West, they swarm about the settlements, stage stations, 
military posts and other detestable places. 
98. DOLICHO^NYX. (Gr. doXixos, doUchos, long: ovv$, omix, claw.) Bobolinks. Sexes 
unlike, but only in the breeding season : ^ black, bulf and white; 9 brownish and yellowish. 
Bill short, conic, fringilline, not nearly as long as head. Wings long and pointed, 1st and 2d 
quills longest, others rapidly graduated. Tail stiffened, with rigid very acute feathers, almost 
like a woodpecker's, shorter than wing. Feet stout ; tarsus shorter than middle toe and claw ; 
claws all very large. One remarkable species, though there are several others in tropical 
America; noted for the peculiar changes of plumage and the ''mad music "of the ^ ; abundant 
in marsh and meadow of the Eastern IT. S.
