fully an inch deep at its junction with the fourchette, which is wide.
The heart and liver are large ; the cesophagus is extremely wide, enabling
the bird to swallow very large portions of its food at once. The skin
may be drawn over the head without any difficulty, and from the body
with ease. The male weighs 4 lb, the female 4| lb. avoirdupois.
The observations which I have made induce me to believe that the pure and rich light-yellowish whiteness of this species belongs to both sexes after a certain age. I have shot specimens which were, as I thought, so young as to be nearly of a uniform light-brown tint, and which puzzled me for several years, as I had at first conceived them to be of a different species. This, indeed, led me to think that, when young, these birds are brown. Others were more or less marked with broad transverse lines of deep brown or black ; but I have seen specimens of both sexes perfectly free from spots, excepting on the occiput, where I have never missed them.
Some twenty years passed; and, during that time, scarcely was there a winter which did not bring several of these hardy natives of the north to the Falls of the Ohio at Louisville. At the break of day, one morning, when I lay hidden in a pile of floated logs, at the Falls of the Ohio, waiting for a shot at some wild geese, I had an opportunity of seeing this Owl secure fish in the following manner:—While watching for their prey on the borders of the " pots," they invariably lay flat on the rock, with the body placed lengthwise along the border of the hole, the head also laid down, but turned towards the water. One might have supposed the bird sound asleep, as it would remain in the same position until a good opportunity of securing a fish occurred, which I believe was never missed ; for, as the latter unwittingly rose to the surface, near the edge, that instant the Owl thrust out the foot next the water, and, with the quickness of lightning, seized it, and drew it out. The Owl then removed to the distance of a few yards, devoured its prey, and returned to the same hole ; or, if it had not perceived any more fish, flew only a few yards over the many pots there, marked a likely one, and alighted at a little distance from it. It then squatted, moved slowly towards the edge, and lay as before watching for an opportunity. Whenever a fish of any size was hooked, as I may say, the Owl struck the other foot also into it, and flew off with it to a considerable distance. In two instances of this kind, I saw the bird carry its prey across the Western or Indiana Shute, into the woods, as if to be quite out of harm's way. I never heard it utter a single note on
