Changes in migratory patterns observed on birds at Cabusao Wetlands

After spending several months at the Cabusao Wetlands, migratory birds are slowly starting to leave reportedly due to the increasing heat. 

According to Abner Avizola, the Wildlife Enforcement Officer of Cabusao, January to February marks the peak of migratory bird activity in Cabusao Wetlands, with activity tapering off by March.

In 2024, however, the birds have lingered into April, indicating changes in migration patterns.

Avizola speculates that global warming and climate change may be prolonging their stay, as they adjust to the changing seasons.

“Maybe sa global warming [o] sa effect kang climate change… ang amihan season, napo-prolong [kaya] na-aadjust [yung migration],” Avizola said.

As temperatures soar in the province, Avizola notes a gradual decline in the presence of migratory birds in the wetlands. He predicts that by May, their presence may dwindle further.

“Parang sa maabot na May, negative na iyan [na presence nila]. Maybe ining ibang mga migratory birds, halimbawa ining mga sandpipers and plowers, nakakamantinir pa man sinda, pero padikit-dikit, nahali na,” Avizola said.

Thousands of migratory birds arrive annually in the Cabusao Wetlands that attracts bird enthusiasts and locals alike. —GMA Regional TV
