The northern rockhopper penguin is found in the South Atlantic and Indian Ocean and breeds on islands in the sub-Antarctic region, especially on Gough Island, Tristan da Cunha, and St. Paul and Amsterdam Islands.
Northern rockhopper penguin populations have declined seriously in the past decades, with over 1 million birds disappearing.
On some islands, this represents a loss of 90% of the population.
Commercial fishing has made inroads into the food that the penguins eat, but other threats include increased predation, egg harvesting, and pollution from ecotourism.
The accidental introduction of the house mouse on nesting sites has led to nest robbing by the rodents. Oil spills present another hazard.
Northern rockhopper penguin populations are currently being monitored closely and an attempt to find out exactly what has caused the decline in their numbers is being sought.
Keeping commercial fishing concerns from trawling near breeding colonies can also help to stabilize populations.
Marine reserves will also give the protection this lovely little penguin needs.
