Asian Waterbird Census records 38 species in Guimaras

1 of 5

Thousands of migratory birds flocked to the island province of Guimaras during the 2026 Annual Asian Waterbird Census, a coordinated biodiversity monitoring effort conducted from Jan. 5–9, according to the Provincial Environment and Natural Resources Office of Guimaras’ Protected Area Management and Biodiversity Conservation Unit.

Census teams documented 38 waterbird species with a total of 2,235 individual sightings, underscoring Guimaras’ ecological value as a stopover and feeding ground for migratory birds.

The results highlight Guimaras’ strategic location along the East Asian–Australasian Flyway, one of the world’s major migratory routes linking breeding and nonbreeding habitats across Alaska, Siberia, Mongolia, China, the Philippines, Australia, and other countries.

Among the most widely distributed species observed across survey sites were the Little Egret (Egretta garzetta), Whiskered Tern (Chlidonias hybrida), and Black-winged Stilt (Himantopus himantopus).

“The AWC emphasizes that the continued protection of Guimaras’ coastal and wetland areas is not merely a local concern but a contribution to global waterbird conservation efforts,” said Regional Executive Director Raul L. Lorilla.

“This survey serves as an important component of a larger international effort to monitor the health of wetland ecosystems and the status of migratory bird populations throughout the East Asian–Australasian Flyway,” he added.

Officials said the 2026 census reinforces the need for consistent monitoring and public support to protect local wildlife and critical habitats.

By conducting the survey annually, the Department of Environment and Natural Resources Region VI can use the data to support evidence-based policies that balance economic development with environmental conservation.

The findings will also help guide future management plans aimed at ensuring Guimaras remains a refuge for migratory birds and other wildlife.

Launched in the 1980s, the Asian Waterbird Census is a long-running citizen science initiative that tracks waterbird populations and wetland conditions across Asia to inform conservation action.

By identifying important sites and monitoring population trends, the AWC supports international conservation agreements, strengthens national strategies, and raises public awareness through the participation of thousands of volunteers worldwide. (DENR6)
