Albatrosses employ orientation and routing strategies similar to yacht racers.

The way goal-oriented birds adjust their travel direction and route in response to wind significantly affects their travel costs. This is expected to be particularly pronounced in pelagic seabirds, which utilize a wind-dependent flight style called dynamic soaring. Dynamic soaring seabirds in situations without a definite goal, e.

The ways in which seabirds navigate over very large spatial scales remain poorly understood. While olfactory and visual information can provide guidance over short distances, their range is often limited to 100s km, far below the navigational capacity of wide-ranging animals such as albatrosses. Infrasound is a form of low-frequency sound that propagates for 1,000s km in the atmosphere.

Contrasting movement strategies among juvenile albatrosses and petrels.

Centre d'Etudes Biologiques de Chizé, UMR 7372 CNRS &Université de La Rochelle, Villiers en Bois, France.
Animal movement is a fundamental eco-evolutionary process yet the behaviour of juvenile animals is largely unknown for many species, especially for soaring seabirds which can range widely over the oceans at low cost. We present an unprecedented dataset of 98 juvenile albatrosses and petrels (nine species), tracked for the first three months after independence. There was a startling diversity within and among species in the type and scale of post-natal movement strategies, ranging from area-restricted to nomadic patterns.

Same-sex behavior in animals fascinates scientists as well as laypeople, partly because of implications about sexual orientation in humans. After all, if animals engage in homosexuality, can it be dismissed as 'unnatural'? A recent paper by Young and colleagues documents long-term female pairs in >30% of Laysan albatross on the Hawaiian island of Oahu. The unrelated females bred successfully, challenging ideas about cooperative breeding, alternative reproductive strategies and perhaps even the evolution of sexual orientation.
