The next, which makes the largest Figure, but is not in reality the largest
Bird, is the Cropper; it is so named, because they usually do, by
attracting the Air, blow up their Crops to an extraordinary bigness, even
so sometimes as to be as large as their Bodies. This sort is esteemed the
better, as it can swell its Crop to the largest Size. The Bodies of this
sort are about the bigness of the smaller Runt, but somewhat more slender.
This sort, like the former, is of various Colours in the Feathers.

The next are those Pigeons call'd Shakers, and are said to be of two sorts,
_viz._ the broad-tail'd Shaker, and the narrow-tail'd Shaker: The reason
which is assign'd for calling them Shakers, is, because they are almost
constant in wagging their Heads and Necks up and down; and the Distinction
made between the broad and narrow-tail'd Shaker, is, because the broad
tail'd sort abounds with Tail-Feathers, about twenty-six in number, as Mr.
_Ray_ observes, and the narrow-tail'd Shakers have fewer in number. These,
when they walk, carry their Tail-Feathers erect, and spread abroad like a
Turkey-Cock. They likewise have diversity of Feathers.

The next I shall take notice of, are the Jacobines, or Cappers: These are
called Cappers from certain Feathers which turn up about the back part of
the Head. There are of these that are rough-footed: these are short-bill'd,
the Iris of their Eye of a Pearl Colour, and the Head is commonly white.

The next is the _Turbit_, commonly so call'd, but what is the occasion of
the Name, is not known, unless _Turbit_, or _Turbeck_, is a Corruption of
the Word _Cortbeck_, or _Cortbeke_, which is the Name the _Hollanders_ give
them, and seems to be derived from the _French_, where _Court-bec_ would
signify a short Bill, which this Pigeon is remarkable for; the Head is
flat, and the Feathers on the Breast spread both ways. These are about the
