Fam. XI. ICTERIDÆ, or TROUPIALS.

The Icteridæ or Troupials constitute a large group of Passerine birds

allied to our Starlings (_Sturnidæ_), of which they take the place in

the New World. They are at once structurally distinguishable from

the Starlings by having only 9 primaries in the wing, just as the

Mniotiltidæ of the New World are in a similar manner distinguishable

from the Sylviidæ.

In America the Icteridæ play an important part, numbering some 130

species, and extending throughout the two continents from north to

south. Of these, 15 species occur in Argentina, and amongst them are

three species of Cow-bird (_Molothrus_), remarkable for their parasitic

habits, of which Hudson's observations have enabled him to give a full

and, for the first time, a tolerably complete account.
