Résumé

Gentoo (Pygoscelis papua) penguin colony population behavior and phenology have been systematically studied on Galindez Island during several seasons since 2015. The detailed observation of bird arrival, nesting, hatch, and crèche has been provided in two colonies at the GAI CEMP site at Galindez Island near the Akademik Vernadsky Ukrainian Antarctic station. Here, we discuss the visual survey results from these colonies obtained during the 2024/25 season. The data validation experiment results, provided for photo captures from time-lapse cameras of the CEMP monitoring project of CCAMLR, obtained during the 2022/23, 2023/24, and 2024/25 seasons, are compared with earlier validation data and discussed.
