WBCP Joins the 2023 Asian Waterbird Census

By Tinggay R. Cinco and Mike Lu

The Asian Waterbird Census (AWC) is part of the global effort by the International Waterbird Census done to monitor the status of migratory waterbirds.  In the Philippines, the assigned government agency tasked to conduct these surveys is the Biodiversity Management Bureau (BMB) of the Department of the Environment and Natural Resources (DENR).

Throughout the years, the WBCP members have volunteered and assisted the DENR in counting waterbirds in the various regions of the country during designated dates from the 2nd to the 3rd week of January, only having a hiatus due to the quarantine restrictions of the Covid-19 pandemic from 2021 to 2022.  The annual AWC is one of the major activities of the WBCP to promote bird conservation awareness and appraise current wetland conditions that may determine the status of bird populations.

For 2023, the BMB-DENR scheduled the AWC on January 7-22, coinciding with the mid-winter migration season in the Northern hemisphere.  

The WBCP participated in the 2023 AWC in several provinces, which included the National Capital Region, Pangasinan, Pampanga, Tarlac, Bataan, Cavite, and Camarines Sur.  Members committed to join and lend their birdwatching skills to survey teams composed of the regional DENR offices and Local Government Units.

The 1st edition of eBon for 2023 wishes to highlight the dedication of WBCP members who volunteer for the Asian Waterbird Census.  Most notably appreciated was the participation of new and active members who were willing to learn and hone their waterbird identification skills.

Quoting WBCP member Juan Mesquida during the AWC in Balanga, the participation of the younger members of the bird club will ensure the continuation of this important survey activity in the future.

This eBon edition presents the 2023 AWC data gathered during the waterbird counts in the various sites.  It also highlights citizen science in action—WBCP members fulfilling the club mandate in contributing not only to the local conservation efforts but also doing every individual’s share in the global community for the responsibility of wildlife protection.

The AWC in Sual, Pangasinan was done upon the invitation of Team Energy Foundation.  A notable observation was that wild vegetation had created a safe habitat for the existing population of Philippine Ducks at the decommissioned ash pond inside the Team Energy Power Plant premises.  At the adjacent Baybay fishponds, nylon mesh nets prevented the birds from feeding and resulted in low wader counts.

Region 3

Canarem, Victoria, Tarlac-January 10, 2012

Lower counts in the Sasmuan Bangkung Malapad Critical Habitat and Ecotourism Area (SMBCHEA) wherein there was an overplanting of mangroves which has encroached in the feeding grounds of the waterbirds. Lesser counts compared to previous years due to unfavorable tidal conditions.  The Sasmuan Pampanga Coastal Wetland is the 8th Ramsar site in the Philippines.  A Slaty-breasted Rail was sighted by Cheta Chua at the SMBCHEA.

There was a notable increase of 8% in waterbird counts, with 14,693 individuals in 2022 to 16,026 in 2023.  Their numbers  at the Balanga Wetland Park were affected by the overgrown mangroves along the shoreline due to over planting.  The mudflats by the Talisay River bank had expanded due to the dumping of dredged materials.

The mudflats were too soft too land. Birds were few and far between; resident birds like the Philippine and Wandering Whistling Ducks were not sighted.
