50 CFR § 21.3 - Definitions.

§ 21.3 Definitions.

In addition to definitions contained in part 10 of this chapter, and unless the context requires otherwise, as used in this part:

Armed Forces means the Army, Navy, Air Force, Marine Corps, Coast Guard, and the National Guard of any State.

Bred in captivity or captive-bred refers to raptors, including eggs, hatched in captivity from parents that mated or otherwise transferred gametes in captivity.

Captivity means that a live raptor is held in a controlled environment that is intensively manipulated by man for the purpose of producing raptors of selected species, and that has boundaries designed to prevent raptors, eggs or gametes of the selected species from entering or leaving the controlled environment. General characteristics of captivity may include, but are not limited to, artificial housing, waste removal, health care, protection from predators, and artificially supplied food.

Conservation measures, as used in § 21.15, means project design or mitigation activities that are reasonable from a scientific, technological, and economic standpoint, and are necessary to avoid, minimize, or mitigate the take of migratory birds or other adverse impacts. Conservation measures should be implemented in a reasonable period of time.

Falconry is caring for and training raptors for pursuit of wild game, and hunting wild game with raptors. Falconry includes the taking of raptors from the wild to use in the sport; and caring for, training, and transporting raptors held for falconry.

Hacking is the temporary release of a raptor held for falconry to the wild so that it must survive on its own.

Hybrid means any bird that results from a cross of genetic material between two separate taxa when one or both are listed at 50 CFR 10.13, and any progeny of those birds.

Imprint, for the purposes of falconry, means a bird that is hand-raised, from 2 weeks of age until it has fledged, and has identified itself with humans rather than its own species. An imprinted bird is considered to be so for its entire lifetime.

Livestock depredation area means a specific geographic location in which depredation by golden eagles has been recognized. The boundaries and duration of a livestock depredation area are declared by U.S.D.A. Wildlife Services or by a State governor.

Military readiness activity, as defined in Pub. L. 107-314, § 315(f), 116 Stat. 2458 (Dec. 2, 2002) [Pub. L. § 319 (c)(1)], includes all training and operations of the Armed Forces that relate to combat, and the adequate and realistic testing of military equipment, vehicles, weapons, and sensors for proper operation and suitability for combat use. It does not include (a) routine operation of installation operating support functions, such as: administrative offices; military exchanges; commissaries; water treatment facilities; storage facilities; schools; housing; motor pools; laundries; morale, welfare, and recreation activities; shops; and mess halls, (b) operation of industrial activities, or (c) construction or demolition of facilities listed above.

Population, as used in § 21.15, means a group of distinct, coexisting, conspecific individuals, whose breeding site fidelity, migration routes, and wintering areas are temporally and spatially stable, sufficiently distinct geographically (at some time of the year), and adequately described so that the population can be effectively monitored to discern changes in its status.

Raptor means a migratory bird of the Order Accipitriformes, the Order Falconiformes, or the Order Strigiformes listed in § 10.13 of this chapter, including the bald eagle (Haliaeetus leucocephalus) and the golden eagle (Aquila chrysaetos).

Resident Canada geese means Canada geese that nest within the lower 48 States and the District of Columbia or that reside within the lower 48 States and the District of Columbia in the months of April, May, June, July, or August.

Secretary of Defense means the Secretary of Defense or any other national defense official who has been nominated by the President and confirmed by the Senate.

Service or we means the U.S. Fish and Wildlife Service, Department of the Interior.

Significant adverse effect on a population, as used in § 21.15, means an effect that could, within a reasonable period of time, diminish the capacity of a population of migratory bird species to sustain itself at a biologically viable level. A population is “biologically viable” when its ability to maintain its genetic diversity, to reproduce, and to function effectively in its native ecosystem is not significantly harmed. This effect may be characterized by increased risk to the population from actions that cause direct mortality or a reduction in fecundity. Assessment of impacts should take into account yearly variations and migratory movements of the impacted species. Due to the significant variability in potential military readiness activities and the species that may be impacted, determinations of significant measurable decline will be made on a case-by-case basis.
