Parrots are gregarious and usually feed and roost in companies, but are at least temporarily monogamous.
They are unable to fly till nearly two years old, and continue for a considerable time after taking wing to roost and hunt with their parents.
They are remarkably heavy sleepers, and are readily captured by the inhabitants ascending the trees on which they roost, and noosing them before they awaken.
On the same side of the Great Valley, south of the Potomac, are the Pinnacle (3007 ft.) and Pidgeon Roost (3400 ft.).
The tidal currents, or races, or roost (as some of them are called locally, from the Icelandic) off many of the isles run with enormous velocity, and whirlpools are of frequent occurrence, and strong enough at times to prove a source of danger to small craft.
