Thai seas boosted by a surprising aerial nutrient delivery from seabirds
A new study reframes how Thailand’s coastlines, coral reefs, and marine life are sustained. Research indicates that flying seabirds provide a steady nutrient input to surface waters as they defecate mid-flight, fertilizing the Gulf of Thailand and the Andaman Sea. This finding highlights natural processes that support Thailand’s vibrant marine ecosystems and tourism-dependent communities.
In a collaboration between researchers from a Japanese university and Thai scholars, lightweight belly-mounted cameras recorded 195 defecation events across 36 hours of seabird flight. The observations reveal that streaked shearwaters and similar species defecate almost exclusively while in flight, a behavior that creates regular aerial nutrient pulses over the sea.
