Naturalists may have concluded that for want of such information, those Birds absent themselves in a different Manner. If the Immenseness of the Globe be considered, and the vast Tracts of land remaining unknown but to its barbarous Natives, 'tis no Wonder we are yet unacquainted with the Retreats of these itinerant Birds.

The Reports of their lying, torpid in Caverns and hollow Trees, and of their telling in the same State at the Bottom of deep Waters, are Notions so ill attested and absurd in themselves, that they deserve no farther Notice.

If with Submission I may offer my own Sentiments, I must join in the general Opinion, with this additional Conjecture, viz. that the Place to which they retire is probably in the same Latitude of the southern Hemisphere, or where they may enjoy the like Temperature of Air, as in the Country from whence they came: By this Change they live in perpetual Summer, which seems absolutely neccessary for their Preservation, because all Summer Birds of Passage subsist on Insects only, and have tender Bills adapted to it, and consequently are unable to subsist in a cold Country, particularly Swallows, Martins, and a few others that feed only on the Wing.

Tho' the warm Parts of the World abound most with Animals in general, Water Fowl may be excepted, there being of them a greater Number and variety of Species in the northern Parts of the World, than between the Tropicks, yet rigid Winters compell them to leave their native frozen Country, and retire southward for Food, and tho' they sometimes approach within a few Degrees of the northern Tropick, very few are ever seen within it, and at the Return of the Spring, they go back again to the North, and there breed: Why Water Fowl particularly should abound most in cold Climates, I can no otherwise attempt to account for, than that as Nature has endowed all Creatures with a Sagacity for their Preservation, so these Birds to avoid the Danger of voracious Animals (to which they are more exposed than Land Birds) choose to inhabit where they least abound: All Rivers and Watery Places in the southern Latitudes abound so with ravenous Fish, Turtles, Aligators, Serpents, and other destructive Creatures, that the extinction of Water Fowl would probably be in Danger, were they wholly confined to these Latitudes: Yet there are some Species of the Duck Kind, peculiar to these torrid Parts of the World, which pearch and roost upon Trees for their greater Security, of these are the Whistling Duck.
