Ring-Necked Duck (Aythya collaris) lives in freshwater wetlands across North America. It feeds on aquatic plants insects. Its conservation status is Least Concern.

A real field recording of the Ring-Necked Duck, made in the wild.
The cinnamon neck ring is usually difficult to observe, making it easy to miss even when the bird is in close view. Because the ring is so subtle, observers often call the species a "ringbill"; the male's bill also bears two white rings, while the female's ring is less pronounced.
The female lays one egg per day, continuing this steady pace until the clutch reaches eight to ten eggs. After the final egg is laid, the clutch is incubated for 25 to 29 days before hatching. During this period the female remains on the nest, and after the ducklings hatch she stays with them until they are capable of flight. This reproductive strategy ensures the young are well-protected during their most vulnerable stage.
Each egg measures 1.9-2.4 cm in length and 1.4-1.7 cm in width, fitting neatly into the shallow bowl-shaped nest the female builds on water. The nest is constructed in dense emergent vegetation, using sedges and woody plants to anchor it securely. This placement protects the eggs from many predators and keeps them stable in the aquatic environment, aiding successful incubation.
In Britain the species is only seen in occasional small flocks, with five birds recorded at Loch Leven in Scotland during September 2003 and four at Standlake in Oxfordshire in April 2015. These sightings illustrate the duck's status as a rare but regular vagrant to western Europe.
Ring-necked duck pairs form only for the breeding season and separate once reproduction is complete, meaning the partnership is strictly seasonal. Pair formation begins during the spring migration, when individuals seek mates on their breeding grounds. Ducks that arrive without a partner usually become non-breeders, while after the clutch is laid the female may stay with the ducklings until they can fly.
