(a)(1) Transportation of all live birds shall be done in a manner that does not cause overheating, excessive cooling, or adverse environmental conditions that could cause discomfort or stress. When climatic or environmental conditions, including temperature, humidity, exposure, ventilation, pressurization, time, or other environmental conditions, or any combination thereof, present a threat to the health or well-being of a live bird, appropriate measures must be taken immediately to alleviate the impact of those conditions. The different climatic and environmental factors prevailing during a journey must be considered when arranging for the transportation of and when transporting live birds. Corrections may include, but would not be limited to:

(i) The temperature and humidity level of any enclosure used during transportation of live birds must be controlled by adequate ventilation or any other means necessary;

(ii) Appropriate care must be taken to ensure that live birds are not subjected to prolonged drafts detrimental to their health or well-being;

(iii) Appropriate care must be taken to ensure that live birds are not exposed to direct heat or cold if detrimental to their health or well-being; and

(iv) During prolonged air transit stops in local climatic conditions that could produce excessive heat for live birds held in aircraft compartments, the aircraft doors must be opened and, if necessary, equipment must be used to control the condition of the air within compartments containing live birds.

(2) In order to determine what climatic and environmental conditions are appropriate for a live bird, factors such as, but not limited to, the bird's age, species, physiological state, last feeding and watering, and acclimation shall be considered when such information is available.

(b) Birds that are not able to maintain a constant body temperature at ambient temperatures must be transported in a brooder or other temperature-regulating unit that effectively assists the bird in maintaining a constant body temperature during transport.

(1) The temperature of the brooder or other temperature-regulating unit must be monitored during transportation and appropriate for the live bird.

(2) Written instructions for the temperature requirements of birds transported in brooders or other temperature-regulating units must be securely affixed to the outside of the primary enclosure used for transporting the bird. The instructions must be attached in accordance with § 3.162(f) in a manner that makes them easily noticed and read.
