Fewer migratory birds seen at Candaba Swamp this year
CANDABA, Pampanga — Water birds, which took refuge from the cold Siberian winds in two spots at the Candaba Swamp here, number only 1,449, the lowest recorded migration rate since 2010, according to the combined tally made on Saturday by the Wild Bird Club of the Philippines (WBCP) and the Department of Environment and Natural Resources (DENR) for the 2018 Asian Waterbird Census (AWC).
Migratory fowls normally make the trip to the swamp from October to February.
“For the first time, I did not use a calculator to count the birds,” said Mike Lu, a WBCP executive committee member, when he joined the recent tabulation at the farm of former Candaba Mayor Jerry Pelayo at Sitio Doña Simang in Barangay Vidal San Pablo here. The community is one of the bird sanctuaries covered by the Saturday census.
The census was timed with the peak migration season.
According to the DENR, the AWC counted 13,160 birds in 2010; 8,725 in 2011; 10,456 in 2012; 5,475 in 2013; 5,149 in 2014; 3,596 in 2015; 5,145 in 2016; and 6,467 in 2017.
Lu said the declining number was a cause for concern. “Like a highway, Candaba is a stopover point for these birds. Ducks like fresh water but there are few of them here at this time,” he said.
Grass have overgrown around ponds at Pelayo’s farm, leaving little room for birds to hibernate or feed. Farmers have also drained other ponds earlier to grow rice, Lu said.
No strong typhoons caused floods last year in this part of the 32,000-hectare swamp that extends to Bulacan province on the south and Nueva Ecija province on the northeast, unlike in 2011 because of Typhoons “Pedring” (international name: Nesat) and “Quiel” (international name: Nalgae).
Mark Vincent Malana, AWC coordinator in Pampanga province, said the local government should intensify efforts to stop duck poaching in the area, as well as understand how climate change might be affecting the flight of birds to Candaba.
The Candaba Swamp is listed by the DENR as an “important bird and biodiversity area in danger.”
The Saturday census did not break any record for the Philippines.
