COW-PEN BIRD.

Towards the end of September, the old and young Cow Birds congregate in vast numbers, and are seen wending their way southward, sometimes by themselves, more frequently intermingled with other species such as the Purple Grakles and the Redwings, which they join in their plundering expeditions. They are to be seen in the Middle States until near the end of October, although unusually severe weather sometimes forces them southward at an earlier period.

This species derives its name from the circumstance of its frequenting cow-pens. In this respect it greatly resembles the European Starling. Like that bird it follows the cattle in the fields, often alights on their backs, and may be seen diligently searching for worms and larvæ among their dung. In spring, the cattle in many parts of the United States are much infested with intestinal worms, which they pass in great quantities, and on these the Cow-bird frequently makes a delicious repast.

It has no song properly so called, but utters a low muttering sort of chuckle, in performing which, it is seen to swell out its throat, and move the feathers there in succession, in a manner very much resembling that of the European Starling.
