Quick answers
How does dynamic soaring let an albatross fly cheaply?
The bird climbs and dives through wind-speed gradients above waves, converting shear into airspeed. Heart-rate loggers show travel costs closer to rest than to flapping flight.
Who is Wisdom the Laysan albatross?
A female banded in 1956 by Chandler Robbins at Midway. She has fledged chicks into her seventh decade — a longevity record that made a single band number famous.
Why are longlines the central threat?
Baited hooks look like squid. One set can kill dozens of birds. Night setting, weighted lines and tori lines cut the kill when fleets actually use them.
What did Coleridge actually do to the bird?
The 1798 Rime made killing an albatross a moral crime. The poem outran the biology and still titles newspaper bycatch stories.
Why is Taiaroa Head important?
The northern royal albatross colony near Dunedin is a mainland breeding site with public hides — rare for a family that usually needs remote islands.
Do mice really eat albatross chicks?
On Gough and some other islands, introduced house mice attack chicks of albatrosses and petrels. Eradication attempts are now as central as hook rules.
Operating a albatross life is a loop: sense, decide, act, and stay inside an energy and legal envelope.
Steps are type-level -- hunt, migrate or spawn -- not a promise that every individual follows the same film sequence.
Principles
Energy in, work out
Squid, fish and fishery offal taken at the surface. Cheap travel, expensive landing — breeding islands are the rare pause.
Information before motion
Olfaction is stronger than in most birds; a surface slick can be smelled before it is seen. Magnetic and wind cues steer basin-scale loops.
Replacement rate
Slow breeders (whales, apes, albatrosses, tigers) cannot outrun a short political cycle. Fast clutch species still fail if the nest site vanishes.
Place is part of the phenotype
A albatross without its lake, ice, anemone or gravel is a different, usually failing, animal.
Human systems are now habitat
Quotas, feeders, reserves and films rewrite survival as much as weather. A hooked bait is an evolutionary mismatch. Mice on nursery islands and plastic in the gyre are the other two ceilings.

Life-cycle steps
02 Climb the shear
Dynamic soaring extracts energy from wave-top wind gradients.
03 Take surface prey
Squid night-rise and discards pull birds onto hooks.
04 Return on a wind
Breeding adults commute thousands of kilometres between chick and forage.
05 One slow chick
Biennial breeding in great albatrosses — a low replacement rate.
06 Fledge into the gyre
Juveniles wander years before first return; Wisdom’s cohort shows how long that ledger runs.
Hard limits
Physiological envelope
A hooked bait is an evolutionary mismatch. Mice on nursery islands and plastic in the gyre are the other two ceilings.
Place dependence
Without the breeding site or forage pulse, brochure behaviour is theoretical.
Human and legal limits
Quotas, listings and trade rules now bound real populations as tightly as weather.
