Anas luzonica Detailed Introduction

The brown necked duck (Anas luzonica) belongs to the family Anatidae. It is commonly found in swamps, rivers, lakes, ponds and estuaries. It sounds like a mallard but rougher. Most of the activities are in the wild grass in the marsh area near the water. It mainly floats on the surface of the water and gets its food underwater, eating plants as the staple food and sometimes animal foods.

The brown neck duck has webbed toes between the ducks, but rarely dives, and swims with its tail out of the water. It is good at feeding, splashing and mating in the water. It feeds mainly on marsh and lake area plants, crabs, lobsters, shrimp, cockroaches, tide worms, and barnacles.

The breeding season is from March to November, with peaks in July and August. A bowl-shaped nest is built from the stems of plants and grasses. The nest rises above the nearby water and is hidden among the water grasses. Each nest lays 8 to 10 eggs and hatches for 25 to 26 days. The young birds leave the nest for 49 days and are usually incubated alone by the female ducks. After hatching, they are still cared for by the female ducks, and the ducklings follow the female ducks for food.
