Bird keepers at the UK's Dudley Zoological Gardens celebrated the royal engagement by naming two rare baby penguins after William and Kate. Humboldt Penguins live on South America's rocky Pacific coastswhere they burrow homes within mountains of accumulated guano (but we're confident the Zoo meant no disrespect!). Vulnerable to extinction in the wild due to over-fishing and ocean acidification, Humboldt Penguins are protected by the US Endangered Species Act. Dudley Zoo's colony of 60 Humboldt Penguins is the UK's largest. 

By royal appointment: Dudley Zoological Gardens Keeper Sam Grove with the rare Humboldt chicks born this week staff at the Midlands tourist attraction have named William and Kate.
