Un esemplare di pappagallo kea allo zoo di Francoforte

Kea ‘Blacky’ sticks its head through the fence at the zoo in Frankfurt Main, Germany, 28 September 2011. Three of the young birds native to New Zealand are now at Frankfurt Zoo after being transferred from Bremerhaven to keep the lonely male ‘Robin’ company at the aviary. Keas are known for their playfulness and intelligence. (EPA/FRANK RUMPENHORST)
