Résumé |
Obtaining aerial high-resolution images of bird nesting colonies using remote-sensing technology such as satellite-based remote sensing, manned aircraft, or Unmanned Aerial Vehicles might not be possible for many researchers due to financial constraints. Kite Aerial Photography (KAP) provides a possible low-cost alternative. We collected digital images of ground-nesting seabirds (i.e., cormorants and penguins) in two different ecosystems using a kite-based platform equipped with consumer-grade digital cameras with time-lapse capability to obtain estimates of breeding population size. KAP proved to be an efficient method for acquiring high-resolution aerial images. We obtained images of colonies of seabirds ranging in size from hundreds to several hundreds of thousands breeding pairs during flights lasting from a few minutes up to three hours, from flat to very steep areas, and in contrasted wind conditions (from 0.5 to 6 Beaufort force). KAP is an efficient low-cost method for acquiring high-resolution aerial images and an alternative to ground-based censuses, especially useful in rugged areas. |
