Wildlife authorities said Tuesday they had seized nearly 100 exotic animals that had been smuggled into the southern Philippines in the second such haul in just two weeks.

Among the creatures confiscated were 66 wild birds, including a rare Pesquet's parrot, as well as assorted reptiles and mammals such as a long-beaked echidna, a Malayan box turtle, and 10 sugar gliders -- squirrel-like animals that can glide from tree to tree.

A total of 93 animals from Indonesia and Australia were seized by maritime police in the waters off the southern island of Mindanao on Saturday, including vulnerable and critically endangered species, said Ali Hadjinasser, the regional chief of the government wildlife board.

Five Filipinos who were transporting the animals were arrested and will be charged with illegal possession and transport of those species, he told AFP.

Some of the animals did not survive their extended confinement in small cages, he said, adding that he was also worried about how to care for and feed the exotic creatures.

The seizure came just a week after wildlife officers, also in the southern Philippines, found almost 100 similar animals from Australia and Indonesia, being transported by van to Manila.

"They (the two shipments) could be connected. They may have one source because the animals were almost the same types. They may have a large stock so they may have divided it into two," Hadjinasser told AFP.

He said the animals were so rare even the wildlife officials could not identify them, and had to ask Filipino hobbyists for help.

The head of the government's wildlife division, Josefina de Leon, said the shipments were suspected to have originated from the same international syndicate which sells the animals to local collectors.

She said the two large seizures in two weeks were a sign of improved training of wildlife authorities and better cooperation from the public.

"Enforcement is better because there are concerned citizens who are now assisting us in catching the perpetrators," she said.

Wildlife officials believe the animals are transported from Indonesia to Malaysia, and then across the porous maritime border to the southern Philippine island of Mindanao.

Aside from endangering the exotic animals, officials fear the smuggling could spread disease to local animal populations.
