| Résumé : | The changed behaviour of semi-wild Red-crested Pochards in an urban pond is described, with emphasis on breeding habits and success. In 1992 and 1993, out of 32 intraspecifically attended ducklings 21.9% reached maturity, and of 31 interspecifically attended ones 16.1%. The high percentage of losses is partly attributed to bad food conditions of the pond. |
