Environment enhancement to promote psychological well-being.
9 C.F.R. § 3.154
in effectEffective: 2024-07-01Dealers, exhibitors, and research facilities must develop, document, and follow a species-appropriate plan for environment enhancement adequate to promote the psychological well-being of birds. The plan must be approved by the attending veterinarian and must be in accordance with the regulations in this subpart and with currently accepted professional standards as cited in appropriate professional journals or reference guides. This plan must be made available to APHIS upon request, and, in the case of research facilities, to officials of any pertinent funding agency. The plan, at a minimum, must address each of the following:
(a) Social grouping. The environment enhancement plan must include specific provisions to address the social needs of species of birds known to exist in social groups in nature. Such specific provisions must be in accordance with currently accepted professional standards as cited in appropriate professional journals or reference guides. The plan may provide for the following exceptions:
(1) If a bird exhibits vicious or overly aggressive behavior, or is debilitated as a result of age or other conditions (e.g., arthritis), it can be housed separately;
(2) Additionally, birds that have or are suspected of having a contagious disease must be isolated from healthy animals in the colony as directed by the attending veterinarian. When an entire group or room of birds is known to have been or believed to be exposed to an infectious agent, the group may be kept intact during the process of diagnosis, treatment, and control.
(3) Birds may not be housed with other species of birds or animals unless they are compatible, do not prevent access to food, water, or shelter by individual animals, and are not known to be hazardous to the health and well-being of each other. Compatibility of birds must be determined in accordance with generally accepted professional practices and actual observations as directed by the attending veterinarian, to ensure that the birds are in fact compatible. Individually housed social species of birds must be able to see and hear birds of their own or compatible species unless the attending veterinarian determines that it would endanger their health, safety, or well-being. If individually housed social species of birds are unable to see and hear birds of their own or compatible species then special attention regarding enhancement to their environment must be provided as specified in paragraph (c)(4) of this section.
(b) Environmental enrichment. The physical environment in the primary enclosures must be enriched by materials or activities that would provide the birds with the means to express noninjurious species-typical activities. Species differences should be considered when determining the type or methods of enrichment. Examples of environmental enrichments include providing perches, swings, mirrors, and other increased cage complexities; providing objects to manipulate; varied food items; using foraging or task-oriented feeding methods; and providing interaction with the care giver or other familiar and knowledgeable person consistent with personnel safety precautions.
(c) Special considerations. Certain birds must be provided special attention regarding enhancement of their environment, based on the needs of the individual species and/or individual bird and in accordance with the instructions of the attending veterinarian. Birds requiring special attention are the following:
(1) Nestlings, chicks, or fledglings;
(2) Those that show signs of being in psychological distress through behavior or appearance;
(3) Those used in research for which the Institutional Animal Care and Use Committee (IACUC)-approved protocol requires restricted activity; and
(4) Individually housed social species of birds that are unable to see and hear birds of their own or compatible species.
(d) Restraint devices. Birds must not be permitted to be maintained in restraint devices unless required for health reasons as determined by the attending veterinarian or by a research proposal approved by the IACUC at research facilities. Any restraining actions must be for the shortest period possible. If the bird is to be restrained for more than 12 hours, it must be provided the opportunity daily for unrestrained activity for at least 1 continuous hour during the period of restraint, unless continuous restraint is required by the research proposal approved by the IACUC at research facilities.
(e) Exemptions. (1) The attending veterinarian may exempt an individual bird from participation in the environment enhancement plan because of its health or condition, or in consideration of its well-being. The basis of the exemption must be recorded by the attending veterinarian for each exempted bird. Unless the basis for the exemption is a permanent condition, the exemption must be reviewed at least every 30 days by the attending veterinarian.
(2) For a research facility, the IACUC may exempt an individual bird from participation in some or all of the otherwise required environment enhancement plans for scientific reasons set forth in the research proposal. The basis of the exemption shall be documented in the approved proposal and must be reviewed at appropriate intervals as determined by the IACUC, but not less than annually.
(3) Records of any exemptions must be maintained by the dealer, exhibitor, or research facility for at least 1 year in accordance with § 3.81(e)(3) and must be made available to APHIS upon request, and, in the case of research facilities, to officials of any pertinent funding agency.
