In ordinary seasons this well-known bird arrives in vast numbers from

the United States, in the month of October, and scattering over the

lowland plains, and slopes of the sea-side hills, assembles in the

guinea-grass fields, in flocks amounting to five hundred or more.

The seed is then ripe, and the black throngs settle down upon it, so

densely, that numbers may be killed at a random discharge. To procure

the seed, the birds perch on the culm, but as the weight would bear

down a single stalk, each grasps several culms in its foot, while it

rifles the panicles. At this time, the males are dressed in the sober

livery of the females. Early in November they depart for the southern

continent, but during their brief stay they are in great request for

the table. Dr. Chamberlaine only echoes the general estimation, when

he says:—“The Butter-bird is a bonne bouche; it is but a mouthful, but

a luscious and delightful one. Their note,” he adds, “during their

migration hither, is simply _ping, ping, ping_:—what it may be in its

native woods, I do not know. But wounded birds have been secured and

kept in cages, and when placed in the same room with a Canary have soon

acquired similar notes, and in time warble with equal strength and

melody.” (Jam. Alm. 1840; p. 25.)

When the spring rains have set in, usually in the month of April, they

again become our transient guests for a few days, on their northward

migration, when the males are conspicuous in their nuptial dress.

Other species of grass are now seeding, and the nutritive farinaceous

grains of many neglected weeds afford them a supply during their brief

sojourn.
