Highlights
Liguasan Marsh, also known as Ligawasan Marsh, is a vast freshwater system in the Philippines, comprising rivers, small lakes, streams, swamps, and seasonally flooded agricultural land. Spanning about 220,000 hectares, it is considered the largest and most intact wetland in the country. It is classified as an "Inland Wetland" by the Ramsar Convention.
The marsh plays a significant ecological role, supporting numerous fish, resident birds, and migratory birds. It is recognized as an "Important Bird Area" with historical records of species like the Philippine Eagle. The video focuses on the Comb-crested Jacana, a notable shore bird found in the marsh.
The team embarks on a journey through the marsh to spot the Comb-crested Jacana. Despite the challenges of an unstable boat and the birds' flighty nature, they eventually managed to observe and photograph this unique species by paddling silently.
While not endemic to the Philippines, the Comb-crested Jacana's population in the country is exclusively found in Liguasan Marsh. Known as "Papagangan" in Maguindanaon, referring to its crown-like crest, this bird possesses long legs and toes adapted for walking on marsh vegetation without sinking. Other notable bird sightings included the Javan Pond Heron, Purple Heron, and Oriental Darter.
Liguasan Marsh is vital for over 112,000 Maguindanaon families who depend on it for fishing and farming. It also plays a crucial role in flood control. However, the marsh faces threats from oil and gas extraction, urbanization, pollution, and historical conflicts. Recent peace efforts offer opportunities for nature and bird tourism, hoping to preserve its beauty and richness.
