New Zealand Fantails chicks. Fantails live up to their name as their tail spreads out just like a woman's fan as they hunt for insects. They're very active birds, constantly moving and rarely holding still for long. These chicks are likely waiting for parents to bring food back for them.

Arusha the Rothschild giraffe calf is nuzzled by its parents at the Schonbrunn Zoo in Vienna, Austria. Arusha - born 5ft 7ins tall after mum's 15 month pregnancy - already has a head for heights after the six foot drop to the ground when Rita gave birth standing up. "The calf was a bit wobbly but within a few minutes mum had it up on its feet and feeding," said one keeper.
