The rockhopper penguins have put NIWA scientists into a quandary.
These birds move out of uninhabited Campbell Island situated nearly 300 nautical miles away from Stewart Island and come back in early October – where do they go?
This has been reported in nzherald.co.nz dated 12th of June 2012.
The birds have distinctive bright red eyes and yellow crests and in the period of between 1942 and 1985, its population has dropped drastically from over 800,000 to hardly 51,000.
The experts rule out extinction but it is a matter of concern because these birds lay two eggs at a time and usually, the first chick does not survive!!
Their diet consists of little krill, crustaceans, juvenile and small fish and small squid.
