About Heron Watch
Heron Watch is a citizen science initiative by NParks to engage the community to collect important data on herons, egrets and bitterns across Singapore.
It is organised biannually as part of NParks' Community in Nature initiative.
Why this matters
The data you collect helps us track patterns in the bird populations over time. This information helps NParks to develop better park management and conservation measures to sustain and enhance these populations.
