Overview

The largest bird in the Galápagos and the only albatross species that breeds in the tropics. Almost the entire world population nests on a single island: Española.

Physical Characteristics

A wingspan of up to 2.3–2.5 metres, a cream-colored head and neck, and a brown body finely marked with wave-like barring — the source of its name — along with a long, pale yellowish bill.

Habitat

Nests on Española’s rocky, sparsely vegetated coastal terrain.

Distribution

Breeding is almost entirely confined to Española, with a very small number of pairs on Isla de la Plata off mainland Ecuador. Outside the breeding season, birds disperse widely over the eastern Pacific as far as Peru.

Diet

Fish, squid, and crustaceans, supplemented by food taken from other seabirds.

Feeding Behaviour

Forages by seizing prey at the surface while floating on the water, and travels vast distances using dynamic soaring over ocean swells.

Reproduction

Lays a single egg per season, typically around April or May. Both parents share roughly two months of incubation and continue to share chick-rearing duties afterward. Pairs are monogamous and often remain together for life.

Courtship

One of the most elaborate courtship displays among seabirds, involving bill circling and clacking, sky-pointing, bowing, and a distinctive side-to-side sway. Young birds often take several years of practice before successfully pairing.

When to Observe It

Present on Española roughly from April to December; birds disperse out to sea for a few months, typically around January to March, once the breeding season ends.

Evolution

The species’ near-total dependence on a single small island is thought to relate to Española’s specific combination of steady onshore winds — needed for such large birds to take off — and its historical lack of ground predators.

Conservation

Listed as Critically Endangered by the IUCN. Longline fishery bycatch across its foraging range and the extremely concentrated breeding population make the species highly vulnerable to any single localized threat.

Galápagos Connection

One of the archipelago’s signature endemic encounters, associated overwhelmingly with a single landing site: Punta Suárez on Española.

Naturalist Insight

Waved albatrosses take off from Española’s cliffs by essentially falling off the edge to catch the wind. Despite ranging over thousands of kilometres of open ocean, the species has never established a comparable breeding colony anywhere else — Española’s wind and cliff geography appear to be, for this bird, effectively irreplaceable.
