Habitat Description

Philippine Duck

Anas luzonica

This bird species was observed in two sites (Marikit and Cozo). In Marikit, the area is a shallow coastal mangrove with a large sandy to a muddy substrate. The middle part has deep mud and silt. This area is dominated by Scyphiphora hydrophyllacea. In Cozo, the mangrove forest is located near the foot of Cozo mountain. The principal vegetation is Avicennia marina in the seaward most associated with Rhizophora apiculata, Bruguiera parviflora, and Bruguiera gymnorrhiza.
