A penguin's waddle is one of nature's weirdest walks
Puddle - a Humboldt penguin - seems more than a little bemused.
And with good reason.
A team of scientists have come to Penguin Beach at London Zoo, installed a hi-tech track and are now trying to lure Puddle and his penguin pals across it.
"Go Puddle, go!" encourages Prof Hutchinson, from the Royal Veterinary College (RVC)
And at last - with a fishy treat to help him along the way - the little bird waddles along the runway.
It is this distinctive walk that scientists from RVC and University of Texas at Austin are here to study.
Beneath the track lie force plates loaded with sensors, which allow the researchers to analyse how these birds get around.
"Penguins move in a really weird way," explains Prof Hutchinson.
"They have a very upright posture like a human, but they also have very short, crouched legs - it is very comical."
