Abstract: | The post‐fledging dependence period is extremely important because it allows young birds the opportunity to develop behavioural skills required for later life. We raised 12 hatchling Brown Boobies Sula leucogaster and attached a miniaturized GPS logger to each bird to examine how flight improves after fledging. The Boobies made daily trips and increased the maximum distance, total distance travelled each day, trip duration and flight speed. Young Boobies seemed to gradually acquire flight skills towards independence. |
