Primary enclosures used to transport live birds.
9 C.F.R. § 3.162
in effectEffective: 2024-07-01Any person subject to the Animal Welfare regulations (this part and parts 1 and 2 of this subchapter) must not transport or deliver for transport in commerce a bird unless the following requirements are met:
(a) Construction of primary enclosures. The bird must be contained in a primary enclosure such as a compartment, transport cage, carton, or crate. Primary enclosures used to transport birds must be constructed so that:
(1) The primary enclosure is strong enough to contain the bird securely and comfortably and to withstand the normal rigors of transportation;
(2) The interior of the enclosure has no sharp points or edges and no protrusions that could injure the bird contained therein;
(3) The bird is at all times securely contained within the enclosure and cannot put any part of its body outside the enclosure in a way that could result in injury to itself, to handlers, or to other persons or to animals nearby;
(4) The bird can be easily and quickly removed from the enclosure in an emergency;
(5) Unless the enclosure is permanently affixed to the conveyance, adequate handholds or other devices such as handles are provided on its exterior, and enable the enclosure to be lifted without tilting it, and ensure that anyone handling the enclosure will not be in contact with the bird contained inside;
(6) Unless the enclosure is permanently affixed to the conveyance, it is clearly marked on top and on one or more sides with the words “Live Animals,” in letters at least 1 inch (2.5 centimeters) high, and with arrows or other markings to indicate the correct upright position of the primary enclosure;
(7) Any material, treatment, paint, preservative, or other chemical used in or on the enclosure is nontoxic to the bird and not harmful to its health or well-being;
(8) A bird that has a fractious or stress-prone disposition must be contained in an enclosure that is padded on the top and sides and has protective substrate on the bottom to prevent injury to the bird during transport;
(9) Proper ventilation is provided to the animal in accordance with paragraph (b) of this section; and
(10) The primary enclosure has a solid, leak-proof bottom or a removable, leak-proof collection tray. If a mesh or other nonsolid floor is used in the enclosure, it must be designed and constructed so that the bird cannot put any part of its body through the holes in the mesh or the openings in the nonsolid floor. If substrate (newspaper, towels, litter, straw, etc.) is used in the primary enclosure, the substrate must be clean and made of a suitably absorbent material that is safe and nontoxic to the birds.
(b) Ventilation. (1) Unless the primary enclosure is permanently affixed to the conveyance, there must be ventilation openings located on two vertical walls of the primary enclosure that are at least 16 percent of the surface area of each such wall or ventilation openings located on all four walls of the primary enclosure that are at least 8 percent of the total surface area of each such wall.
(2) Unless the primary enclosure is permanently affixed to the conveyance, projecting rims or other devices must be on the exterior of the outside walls with any ventilation openings to prevent obstruction of the ventilation openings. The projecting rims or similar devices must be large enough to provide a minimum air circulation space of 0.75 inches (1.9 centimeters) between the primary enclosure and anything the enclosure is adjacent to, unless 90 percent or greater of the surface area of the enclosure wall is open (e.g., cage mesh).
(3) Any visually obscuring mesh used to provide security for the bird in the enclosure must not interfere with proper ventilation.
(4) If a primary enclosure is permanently affixed within the animal cargo space of the primary conveyance so that the front opening is the only source of ventilation for such primary enclosure, the front opening must open directly to the outside or to an unobstructed aisle or passageway within the primary conveyance. Such front ventilation opening must be at least 90 percent of the total surface area of the front wall of the primary enclosure and covered with bars, wire mesh, or smooth expanded metal.
(c) Cleaning of primary enclosures. A primary enclosure used to hold or transport birds in commerce must be cleaned and sanitized before each use in accordance with § 3.158 by the dealer, research facility, exhibitor, or operator of an auction sale.
(d) Compatibility. Live birds transported in the same primary enclosure must be of the same species or compatible species and maintained in compatible groups. If more than one bird is being transported, socially dependent birds must be able to see and hear each other.
(e) Space and placement. Primary enclosures used to transport live birds must be large enough to ensure that each bird contained therein has sufficient space to turn about freely and to make normal postural adjustments; Provided, however, That certain species may be restricted in their movements according to professionally accepted standards when such freedom of movement would constitute a danger to the birds, their handlers, or other persons.
(f) Accompanying documents and records. Documents accompanying the shipment must be attached in an easily accessible manner to the outside of a primary enclosure which is part of such shipment and must not obstruct ventilation openings.
