The BA also contains appendices. At Appendix V,

under the heading “Visual Monitoring Methods for the Horse

Butte Bald Eagle Nesting and Foraging Area,” the stated

goals and objectives for visual monitoring of the “Horse

Butte bald eagle nesting territory and bald eagle use of

the Madison Arm of Hebgen Lake are” to: (1) assess

occupancy and activity of the Horse Butte nesting

territory; (2) to attempt to assess the effects of the

bison capture facility on eagles nesting and foraging

activities on eagles in the Horse Butte breeding territory

and the Madison Arm of Hebgen Lake; (3) to determine

whether the Horse Butte eagles initiate nesting and

incubation; (4) to determine if the Horse Butte eagles

complete incubation, and if not when incubation ceased; (5)

to determine whether the Horse Butte nest was productive,

and; (6) to assess any changes in foraging/perching uses

“along the Madison Arm of Hebgen Lake before, during and

after capture facility operations and construction.”See

EA, Appendix V to Appendix B, p. 34 (emphasis added).
