Crane's kung-fu kick is what comes naturally
Don't worry. They're only showing off – apparently.
These two young Eurasian cranes are displaying natural kung-fu skills which, in the wild, will come in very handy.
The two youngsters were showing off in front of each other at the Great Crane Project in Gloucestershire, before being released next month on to the Somerset Levels.
At the project (a partnership between the Wildfowl and Wetlands Trust, the RSPB and Pensthorpe Conservation Trust) they have been taught how to forage and avoid danger by human carers, who wear disguises to prevent the cranes from becoming tame.
WWT aviculturist Amy King said: ''We are surrogate parents to the birds and try to teach them all they need to survive, but some things they just pick up on their own.
"Here the young cranes are sparring, as many young animals do. It looks dramatic but for now it is just practice.
"Once in the wild, they'll use these skills to determine their place in the pecking order and, if they need, to battle potential predators."
Cranes were once a widespread and culturally significant part of British wildlife but by 400 years ago, they had become extinct as a breeding bird because of the drainage of wetlands and over hunting.
