Response of fall-staging brant and Canada geese to aircraft overflights in southwestern Alaska

Article Abstract:

Research undertaken at Izembek Lagoon on the Bering Sea close to the end of the Alaska Peninsula into the response of fall-staging brant and Canada geese to aircraft overflights established that 75% of the brant flocks flew in response to aircraft overflights. Brant response to aircraft at different altitudes was inconsistent. Canada goose flocks hardly ever flew in response to fixed-wing or rotary-wing aircraft. Lateral distance between aircraft and flock was the most significant parameter in anticipating response of brant and Canada geese to overflights.

Response of fall-staging brant and Canada geese to aircraft overflights in southwestern Alaska

Article Abstract:

The behavioral responses of Pacific brant and Canada geese to aircraft overflights in southwestern Alaska during fall staging were investigated. Predictive models of brant and Canada goose response to aircraft altitude, noise, type and lateral distance from flocks were developed for this purpose. Results showed that a significantly higher number of brant flew in response to overflights than did Canada goose flocks. The implications of the findings for wildlife management were discussed.
