“An animal normally falling within an established category of ferae naturae shall nevertheless be classified as domitae naturae (a) if it is born, spawned or hatched in captivity; or (b) having been brought into captivity after birth, spawning or hatching, its captor or such other person to whose custody it is transferred evinces an intention to retain the same in captivity, in either case unless and until it is released from captivity by its captor or such other person.” (a) if it is born, spawned or hatched in captivity; or (b) having been brought into captivity after birth, spawning or hatching, its captor or such other person to whose custody it is transferred evinces an intention to retain the same in captivity, in either case unless and until it is released from captivity by its captor or such other person.”
“There is no absolute property in wild animals while living, and they are not goods or chattels. There may, however, be what is known as a qualified property in them, either: (1) per industriam; (2) ratione impotentiae et loci; or (3) ratione soli and ratione privilegii. This qualified property is defeasible, for if the animal has no intention to return, but resumes its wildness and is at large again and not under pursuit, it is free and may be taken by another person. Thus the special right of property, called qualified property, if conferred ratione impotentiae et loci, ratione soli or ratione privilegii, is in substance an exclusive right to reduce the wild animal into possession, but if acquired per industriam it is an exclusive right to the possession of the wild animal which, in the case of a living animal, will continue while it has the intention to return.”
“The property in animals ferae naturae while they are on the soil belongs to the owner of the soil and he may grant a right to others to come and take them by a grant of hunting, shooting, fowling and so forth; that right may be granted by the owner of the fee simple, and such a grant is a licence of a profit à prendre.”
“With respect to wild and unreclaimed animals therefore, there can be no doubt that no property exists in them so long as they remain in the state of nature. It is also equally certain that when killed or reclaimed by the owner of the land on which they are found, or by his authority, they become at once his property, absolutely when they are killed, and in a qualified manner when they are reclaimed.”
“If a person chooses to pay for the amusement of catching fish and leaving them in the water of course he can do so, but that is not what is understood by lawyers or men of sense as a right of fishing.”
“For if I have a singing bird, though it be not pecuniarily profitable, yet it refreshes my spirits and gives me good health, which is a greater treasure than great riches. So if anyone takes it from me he does me much damage for which I shall have an action.”
“§67. For wild beasts, birds, and fishes, as soon as they are captured, become, by natural law, the property of the captor, but only continue such so long as they continue in his power; after breaking from his custody and recovering their natural liberty, they may become the property of the next occupant; for the ownership of the first captor is terminated. Their natural liberty is deemed to be recovered when they have escaped from his sight, or, though they continue in his sight, when they are difficult to recapture. §68. In the case of those wild animals, however, which are in the habit of going away and returning, as pigeons, and bees, and deer, which habitually visit the forests and return, the rule has been handed down, that only the cessation of the intention of returning is the termination of ownership, and then the property in them is acquired by the next occupant; the intention of returning is held to be lost when the habit of returning is discontinued.”
“A qualified property may subsist in animals ferae naturae per industriam hominis; by a man’s reclaiming and making them tame by art, industry and education, or by so confining them within his own immediate power that they cannot escape and use their natural liberty. … it may happen that [animals ferae naturae] shall be sometimes tamed and confined by the art and industry of man. Such as are deer in a park, hares or rabbits in an enclosed warren, doves in a dovehouse, pheasants or partridges in a mew, hawks that are fed and commanded by their owner and fish in a private pond or in trunks. These are no longer the property of a man than while they continue in his keeping or actual possession; but if at any time they regain their natural liberty his property instantly ceases unless they have animum revertendi, which is only to be known by their usual custom of returning.”
“It is not every custodia, therefore, which is sufficient; whoever, for instance, keeps wild animals in a park, or fish in a lake, has undoubtedly done something to secure them, but it does not depend on his mere will, but on a variety of accidents, whether he can actually catch them when he wishes, consequently possession is not here retained; quite otherwise with fish kept in a stew “Stew” in this context means “a pond or tank in which fish are kept until ready for the table”: Oxford English Dictionary, meaning 2a. or animals in a yard, because then they may be caught at any moment.”
“The whole of this argument comes down to what Blackstone means when he says ‘and have power to pursue them’” and later “It follows, therefore, that you cannot demand entry upon another man’s land for the purpose of retaking animals”
“12. Wild beasts, birds, fish and all animals, which live either in the sea, the air, or the earth, so soon as they are taken by anyone, immediately become by the law of nations the property of the captor; for natural reason gives to the first occupant that which had no previous owner. And it is immaterial whether a man takes wild beasts or birds upon his own ground, or on that of another. Of course anyone who enters the ground of another for the sake of hunting or fowling, may be prohibited by the proprietor, if he perceives his intention of entering. Whatever of this kind you take is regarded as your property,so long as it remains in your power, but when it has escaped and recovered its natural liberty, it ceases to be yours, and again becomes the property of him who captures it. It is considered to have recovered its natural liberty, if it has either escaped out of your sight, or if, though not out of your sight, it yet could not be pursued without great difficulty.”
“To a certain extent, and as far as Barbeyrac appears to me to go, his objections to Puffendorf’s definition of occupancy are reasonable and correct. That is to say, that actual bodily seizure is not indispensable to acquire right to, or possession of, wild beasts; but that, on the contrary, the mortal wounding of such beasts, by one not abandoning his pursuit, may, with the utmost propriety, be deemed possession of him; since, thereby, the pursuer manifests an unequivocal intention of appropriating the animal to his individual use, has deprived him of his natural liberty, and brought him within his certain control. So also, encompassing and securing such animals with nets and toils, or otherwise intercepting them in such a manner as to deprive them of their natural liberty, and render escape impossible, may justly be deemed to give possession of them to those persons who, by their industry and labour, have used such means of apprehending them.”
“9. Qualified property per industriam. A qualified property in living animals ferae naturae obtained per industriam arises by lawfully taking, taming, or reclaiming them. Animals ferae naturae become the property of any person who takes, tames, or reclaims them, until they regain their natural liberty. Animals such as deer, swans, and doves are the subjects of this qualified property, which is lost if they regain their natural liberty, and have not the intention to return. Thus a claim for trespass or conversion will lie for taking a captive thrush, singing bird, muskrat, parrot or ape, because, although they are ferae naturae, they have been held to be merchandise and valuable when in a state of captivity; and for taking doves out of a dovehouse, hares, pheasants, or partridges in a warren or inclosure, deer in a park, a hawk if tame, fish in a stew pond, rabbits in a warren, swans marked or in private waters, or bees in a hive. …”
