Scientific and Ecological Features of the White-Winged Duck
Asarcornis scutulata, the scientific name of the White-Winged Duck, reflects a careful naming convention used in ornithology. The genus name Asarcornis is derived from the Ancient Greek words, asarcón meaning "without a crest" and ornis meaning "bird," while the species name scutulata comes from the Latin word scutella, meaning a "dish" or "shallow plate." These names help in understanding the evolutionary and anatomical context of the species.
Appearance and Behavior
The White-Winged Duck is a medium-sized duck with a distinctive appearance. It has white wing patches, a black crown, and a pale yellow face, making it easily recognizable. Measuring between 44 to 46 cm in length, it is known for its elegance and graceful movements both in water and on land. Its diet primarily consists of aquatic plants and small invertebrates, which it forages for with great dexterity.
Life Cycle and Habitat
The breeding season of the White-Winged Duck is believed to be from February to June, during which time the males are most active and vocal. The females lay a clutch of 7 to 11 eggs, which they incubate for about 28 days. Juveniles are capable of swimming and diving almost immediately after hatching. The species is often found in swampy areas, reed beds, and shallow lakes, making Assam's unique wetland ecosystems ideal habitat.
