Life-history trade-offs and #senescence in black-browed #albatrosses from Kerguelen and Bird Island
Black-browed #albatrosses breeding in more variable environments display slower life histories (slow, late-onset reproductive senescence) and greater among-individual variation in life-history strategies
Key areas vital to #EndangeredSpecies like #albatrosses and #penguins lack full #sanctuary protections, and some high-conservation zones will still permit #fishing. Now is the time to continue pushing for more!
This is a huge moment for #MarineConservation, but we need to demand #governments to really do all they can!

Reproductive and #Foraging Energetics of High Latitude #Penguins, #Albatrosses and Pinnipeds: Implications for Life History Patterns

Animals cover astonishing distances when they are looking for food. While caribou, reindeer and wolves clock up impressive mileage on land, seabirds are unrivaled in their traveling distances. Arctic terns travel from the Arctic to Antarctica and back as part of their annual migration. Wandering albatrosses (Diomedea exulans) fly the equivalent of ten times to the moon and back over their lifetimes.
World's Largest #Seabirds Follow Sound Across The #Ocean to Faraway Food

#Albatrosses orient toward #infrasound while foraging https://www.pnas.org/doi/10.1073/pnas.2314980120
"areas of high wave activity can be associated with upwellings – where #fish are brought to the surface. Infrasound could provide information about where these areas are, and inform #birds of good foraging patches."
First evidence that #albatrosses use infrasound to navigate long journeys

#Albatross movement suggests sensitivity to #infrasound cues at sea: Natasha Gillies et al. https://www.pnas.org/doi/10.1073/pnas.2218679120
"#Microbaroms are a type of infrasound associated with colliding #ocean waves. Such wavy areas are also associated with strong winds, which albatrosses depend on to help them fly efficiently."
A new study by the University of Liverpool provides the first evidence that wandering albatrosses, one of the widest-ranging seabirds, may use infrasound to help them navigate long and featureless foraging trips covering thousands of miles.
