Lovelace, the rockhopper penguin that answers life's questions in the animated film "Happy Feet", probably would be just as stumped as the researchers who reported Friday that the population of his northern relatives has declined by 90 percent over the last 50 years.
The population of northern rockhopper penguins once reached into the millions, but now the largest colonies are estimated at between 32,000 to 65,000 pairs on Gough Island, and 40,000 to 50,000 pairs on Tristan da Cunha Island, according to a study in the journal Bird Conservation International.
Those two South Atlantic islands, which are British overseas territories, account for more than 80 percent of the total species population.
