Although so essentially a bird of the sea-shore, yet in August many scores of these birds come up the Delaware River as far as tide-water extends, feeding upon the mud-flats and gravel-bars, and occasionally wending their way up along the courses of the creeks until they find themselves well into the country. It is interesting to watch them as they run in and out among the little hills and hollows of the mud in quest of their prey. They are happy, light-hearted fellows, who do not begrudge, when some racy tidbit has rewarded their hunting, to pipe a few notes of thanks to Him who watches as tenderly over them as over the mighty lords of the earth. BOB WHITE. Somewhat related to the grouse is the Quail, as he is called in the Northern States, or “Bob White,” his universally recognized appellation. His scientific name is _Ortyx Virginianus_. Differing from the Old World partridges, he has been assigned a place in the sub-family Odontophorinæ, of which five genera are said to exist, most of them being restricted to the extreme south-west of our country. His habits and history are full of interest to everybody. Quails are restless, uneasy birds, attached to one place while rearing their family, but immediately upon the brood becoming able to travel, commencing their wanderings. There is no accounting for these movements, which sometimes deprive a whole district of their presence for a time, to populate a neighboring region previously without them. When such journeys are undertaken, a large number of birds participate, travelling on foot, and passing steadily through districts where food is plentiful, and seemingly without any definite destination in mind, so loath are they to use their wings, that in attempting to cross wide rivers and inlets immense numbers are said to perish. A limited and partial migration, it is highly probable, takes place annually from the more northern to warmer latitudes, influenced in its extent by the comparative severity of the seasons, being more distinctly migrating west than east of the Delaware River.
