Adélie Blues

Adélie populations have fallen by more than 65% in the past 25 years. The biggest threat to them right now is climate change.

In parts of the Antarctic peninsula, sea ice cover has reduced by over 60% in 30 years. One of the Adélies’ main food source, krill, needs ice to breed and feed under, and the loss of ice is causing a decline in krill in some areas. Warmer temperatures can also have an affect on chick hatching times, and they may hatch at times when food is scarce.
