His frequent choice of an old dovecote as a home was misunderstood. The ignorant countryman thought it was in order to prey on the young pigeons that he selected a corner there, whereas--and Waterton was the first to record the bird’s reason, after watching the doings of a pair of Barn Owls in his dovecote--the Owls were there to prey on the pigeons’ enemies, and Owls and Pigeons lived amicably together in the same home. Lord Cathcart, in a paper contributed to the Royal Agricultural Society, said: “Our ancestors, wiser than we, always made in their great barns ingress for Owls--an owl-hole, with often a stone perch.” And the Rev. F. O. Morris tells of a pair of this species which lived in a barn near Norwich, and were so fearless that they would stay there whilst the men were threshing; they waited on the flails as rooks do on the plough, and if a mouse were dislodged by the removal of a sheaf they would pounce upon it without minding the men’s presence. They hunt mice amongst the stacks, too, in the farmyard, staying there all night often, if mice abound. As E. Newman says, “The farmer pays the price of a sack of grain for every Owl nailed to his barn door, because that Owl would have destroyed mice every night, and these mice, being relieved of their oppressive enemy, would, in a very short time, consume a sack of wheat, peas, or beans.” Owing to its very deep plumage, the Barn Owl looks larger than it is. Its eye is dark-coloured, almost black: its glance is directed forwards. The facial disk is very prominent; at rest, it is heart-shaped, and it is edged with white and rust-colour. The bill is yellowish in colour, and is slightly hooked. The legs are scantily feathered, and the toes almost bare: the claw of the middle toe is serrated along its inner edge. The body-plumage is soft as silk, and yielding, and thickly pearled with white and dark markings on the beautiful ash-grey back. The flanks are pale with a reddish tinge, in places very bright, and sprinkled with tiny pearl-like spots of light and dark colour. THE TAWNY OR WOOD-OWL. (_Syrnium alúco._) The Wood Owl, known also as the Brown or Tawny Owl, has the admirable trait of constancy, for it is said he mates for life and the pair return year after year to the same tree to nest. In the month of September you will hear him hooting in the woods more than at any other time of the year. He is not so constant in his choice of locality, but like many other birds he and his kind will disappear from a district without any apparent reason, to return to it again after a time. No doubt they follow their food supply; the small creatures they feed on--mice, rats, shrews, and squirrels--all disappear in the same fashion to re-appear elsewhere; the movements of these being no doubt ruled by the same conditions of suitable food, its scarcity or its plenty. * * * * *
