A baby elephant misjudged the size of her backside and found herself stuck between two trees.

The two-year-old jumbo named Valentine was out for a morning walk with her handler when she tried to squeeze through the gap.

Footage shows how Valentine's rear end was wedged between the two trees in the jungle in Chiang Mai, northern Thailand on August 6.

The elephant had to force its way through the trunks before breaking loose and stumbling and slipping over onto her knee.

Valentine's mahout said he was unharmed after the minor scrape. He added: ''She is fine and is being taken well care of with the other elephants."

Thailand has at least 2,000 elephants living in the wild and a similar number in captivity. They live in sanctuaries, elephant parks, zoos, tourist resorts or with private owners who use them for weddings and religious ceremonies.

Valentine lives at the Elephant Freedom Village, a non-profit organisation that rescues elephants to ''undo the damage done by humans'' and over time ''return them to the forest where they belong.''

The organisation said their elephants spend 90 per cent of their time in the forests and 10 per cent in sheltered paddocks at night, where ''they are given fresh piles of food to graze from; enough to sustain them until the morning hours.''
