Mexican authorities have put eight lions, two lynxes, a puma and a coyote aboard two military planes for a special trip to a Colorado wildlife sanctuary after the animals were found mistreated or abandoned.

Wednesday's flight aboard two Mexican Navy aircraft was the second instalment in an airlift that will eventually take about two dozen animals to The Wild Animal Sanctuary in Keenesburg, Colorado.

Biologist Ignacio Millan said it was the first time Mexico's Navy had participated in the animal relocation effort.

Millan said the lions, lynxes and puma had been taken from private homes, zoos or circuses where they were often mistreated.

The coyote had been used in witchcraft ceremonies.

Millan said that nine tigers still remain to be transferred to the sanctuary, where animals can roam relatively freely
