Aerial Photographic Census of Birds in the Windmill Islands in 1990-91
Entry ID: ASAC_1219_AAT_Img_C_90

Abstract: Population data derived from counts of penguins on aerial photographs taken at 500m altitude. Odbert Island colonies were not photographed as the island is within ASPA 103. 23 flight runs were made. Census data for Whitney Point and Shirley Island were included in Woehler et al 1994. Census data for the remaining islands will be incorporated into a regional synthesis following aerial photography planned for 2004/05.

Penguins were counted from the photographs by eye.

This project was instigated under a one off ASAC project (ASAC_234), but has now been subsumed under ASAC_1219.
