| Abstract: | We conducted experimental photographic surveys of black brant and
Canada geese in a pre-migration staging area on the Alaska Peninsula to compare
precision and efficiency of this technique to currently employed ocular
estimates. Video and digital cameras sensitive to near infrared and visible
radiation were tested at various altitudes and with lenses of different focal
length. Using information from these tests, we constructed an artifical
population of geese to determine sampling effort and efficiency of the
technique. |
