Resumo(s)
A Gray-headed Albatross (Thalassarche chrysostoma) was recorded traveling, in the
course of a foraging trip, at a minimum average ground speed of >110 km h–1 for ~9 h with virtually
no rest. A er taking into account the sinuosity of albatross fl ight, actual mean ground speed
was predicted to be ≥127 km h–1, achieved in association with high tailwinds during an Antarctic
storm. Despite its high speed and the storminess of the sea, the albatross still managed to successfully
locate and capture prey at a rate comparable to that achieved under less extreme conditions.
This individual’s performance suggests that albatrosses have the capacity to maintain positive
energy budgets while quickly covering long distances and taking advantage of the strong winds
that are frequent in the Southern Ocean.
