November 21, 2015 – Grey-headed Albatross (Thalassarche chrysostoma)

Breeding on sub-Antarctic islands, these albatrosses are found mostly in the South Atlantic Ocean, though some circumnavigate the globe between breeding cycles. They eat fish, squid, and crustaceans, feeding mostly lampreys to their chicks. Breeding every two years, they build nests from mud and grass and lay one egg which is incubated mostly by the male. Chicks spend three or four days hatching and aren’t able to breed until they are at least seven years old. They are classified as Vulnerable by the IUCN, mostly due to deaths from longline fishing. Rising sea-surface temperatures also seem to be causing a shortage of food for them.
