Birds vanishing in the Philippines

CANDABA, Philippines (AFP) – The number of birds flying south to important wintering grounds in the Philippines has fallen sharply this year, with experts saying the dramatic demise of wetlands and hunting are to blame.

Despite some harsh, cold weather across the Eurasian landmass, some waterbirds that usually migrate in huge flocks to the tropical islands have been completely absent, said Philippine-based Danish ornithologist Arne Jensen.

"The flyway populations of several waterbird species are in constant and dramatic decline," Jensen, who advises the Philippine government on species conservation, told AFP.

"Hence the urgent need to establish real and well-managed, hunting-free waterbird sanctuaries along the migratory flyways."

Candaba, a swamp two hours' drive north of Manila that has long been used as a pit stop by hundreds of species as they fly staggering distances between the Arctic Circle and Australia, appears emblematic of the downfall.

Jensen said that bird watchers routinely counted 100,000 ducks at Candaba in the 1980s as they stopped there for a rest while traversing the East Asian-Australasian flyway.

But volunteers recorded just 8,725 waterbirds and 41 species during the annual census last weekend, Wild Bird Club of the Philippines president Michael Lu told AFP at Candaba at the end of the count.

Northern pintails, common pochards, and green-winged teals were absent, and just one tufted duck was seen, while numbers for northern shovellers shrank and only garganeys were easily seen along with resident Philippine ducks.

Lu said the number of waterbirds counted at Candaba was down from more than 11,000 last year.

"The main threat is hunting," said Lu, amid occasional loud bangs that were apparently gunfire or firecrackers set off by local residents seeking to flush out the birds.

But Lu also pointed to the dramatic shrinkage in the size of the swamp over the past 50 years as the region was converted into farmland, mainly rice fields.

The swamp two generations ago covered 27,000 hectares (66,690 acres), but it is now just 77 hectares -- or less than one percent of its original size -- according to figures provided by Lu, Jensen and the local government.

Hunters, farmers, and watersports also threaten Paoay Lake, another wild bird habitat in the far north of the Philippines that is close to southern China.

The lake lacks surface plant life after the late dictator Ferdinand Marcos ordered the water lilies removed so he could jetski from his lakeside mansion, while a former local official used to shoot ducks there, Lu said.
