Eagle Disturbance Take Permits and Nest Take Permits
Protections
Eagle Disturbance Protections
The Bald and Golden Eagle Protection Act affords protections to eagles including assuring they are not disturbed. Disturbance to eagles is one of the forms of "take" prohibited by the law (16 U.S.C. 668d). Disturb means "to agitate or bother a bald or golden eagle to a degree that causes, or is likely to cause, based on the best scientific information available, (1) injury to an eagle, (2) a decrease in its productivity, by substantially interfering with normal breeding, feeding, or sheltering behavior, or (3) nest abandonment, by substantially interfering with normal breeding, feeding, or sheltering behavior" (50 CFR 22.6).
Note that disturbance to eagles may be caused not only by visible human activity and/or human noise, disturbance to eagles can also come in the form of removing eagle habitat (including breeding, foraging, and sheltering habitat) from the landscape to the extent that an eagle pair abandons their territory and the territory is lost.
Eagle Nest Protections
Along with protecting eagles, the Bald and Golden Eagle Protection Act also protects eagle nests. Eagle nests are protected at all times, not just when the nests are in use by eagles. This means eagle nests can never be removed, destroyed, moved, tampered with, or obstructed, no matter what time of year it is, without a permit.
An eagle nest is defined as "any assemblage of materials built, maintained, or used by bald eagles or golden eagles for the purpose of reproduction. An eagle nest remains an eagle nest until it becomes so diminished, or the nest substrate upon which it is built fails, that the nest is no longer usable and is not likely to become usable to eagles, as determined by a Federal, Tribal, or State eagle biologist" (50 CFR 22.6).
The following are all considered eagle nests and are protected (unless the nests are determined by a Federal, Tribal, or State eagle biologist to no longer be usable):
- Any nest constructed by an eagle, even if the nest is never finished or used.
- A nest built by another bird that is subsequently used by an eagle for reproduction.
- A nest constructed by an eagle that is subsequently used by another species, such as owls or osprey.
Note that if nest take removes all available nesting substrate from an eagle pair's territory, this can lead to abandonment and loss of the eagle territory, which constitutes a form of disturbance take.
