_Owls._--When an owl hoots or screeches, sitting on the top of a house, or by the side of a window, it is said to foretel death. "The fact," says Forster, "seems to be this: the Owl, as Virgil justly observes, is more noisy at the change of weather, and as it often happens that patients with lingering diseases die at the change of weather, so the Owl seems, by a mistaken association of ideas, to forebode the calamity." _Peacocks_ squalling by night often foretel a rainy day. Forster adds, "This prognostic does not often fail; and the indication is made more certain by the crowing of Cocks all day, the braying of the Donkey, the low flight of Swallows, the aching of rheumatic persons, and by the frequent appearance of spiders on the walls of the house." _Pigeons._--It is a sign of rain when Pigeons return slowly to the dove-houses before the usual time of day. _Ravens_, when observed early in the morning, at a great height in the air, soaring round and round, and uttering a hoarse, croaking sound, indicate that the day will be fine. On the contrary, this bird affords us a sign of coming rain by another sort of cry; the difference between these two voices being more easily learned from nature than described. The Raven frequenting the shore and dipping himself in the water is also a sign of rain. _Redbreasts_, when they, with more than usual familiarity, lodge on our window-frames, and peck against the glass with their bills, indicate severe weather, of which they have a presentiment, which brings them nearer to the habitations of man. _Rooks_ gathering together, and returning home from their pastures early, and at unwonted hours, forebode rain. When Rooks whirl round in the air rapidly, and come down in small flocks, making a roaring noise with their wings, rough weather invariably follows. On the contrary, when Rooks are very noisy about their trees, and fly about as if rejoicing, Virgil assures us they foresee a return of fine weather, and an end of the showers. _Spiders_, when seen crawling on the walls more than usual, indicate rain. "This prognostic," says Forster, "seldom fails, I have noticed it for many years, particularly in winter, but more or less at all times of the year. In summer the quantity of webs of the garden spiders denote fair weather." _Swallows_, in fine and settled weather, fly higher in the air than they do just before or during a showery or rainy time. Then, also, Swallows flying low, and skimming over the surface of a meadow where there is tolerably long grass, frequently stop, and hang about the blades, as if they were gathering insects lodged there. _Swans_, when they fly against the wind, portend rain, a sign frequently fulfilled. _Toads_, when they come from their holes in an unusual number in the evening, although the ground be still dry, foreshow the coming rain, which will generally fall more or less during the night.
