A German zoo's plans to tempt its gay penguins to go straight by importing more females has been declared a failure.
The female penguins were flown in especially from Sweden in an effort to encourage the Humboldt penguins at the Bremerhaven Zoo to reproduce.
But the six homosexual penguins showed no interest in their new female companions and remained faithful to each other.
Zoo Director Heike Kueck said: "The relationships were apparently too strong."
A keeper confirmed that the male couples had adopted rocks which they were guarding like eggs in their caves.
