The Falklands are found in freshwater lakes, swamps, open water, and the surrounding lush vegetation. Omnivorous, feeding on aquatic invertebrates and plant seeds in shallow waters. Often foraging in shallow water where vegetation flourishes. Foraging activities are mainly in the early morning and dusk, during the day more rest on the shore or floating on the open water to sleep. Foraging methods mainly rely on diving to feed, generally in the water is not too deep, and sometimes in the shallow water at the water's edge to extend the head into the water, or tail up into the water to feed.

Falkland ducks usually live alone or in pairs and do not form clusters. Male ducks have a strong sense of territorial spawning ground, and the nest site is generally chosen in the lakeside vegetation. The nests are built from October to January, and each nest lays 6 to 8 eggs, and the incubation period is about 26 to 28 days. The ducklings are black brown on top and yellow on the bottom.

Lake Alautra was declared a Ramsar Wetland of international significance in 2003 and has been working on area conservation and restoration of wildlife habitat, which benefits locally threatened and endangered species. Enhanced conservation measures include education and awareness programmes, participation in environmental monitoring by local communities, and continued search for the remaining Falklands diving duck. Establish a reserve mechanism and ban hunting in the area.

After an expedition in July 2009 found that there were fewer than 20 adult Falkland dives on the island, of which only six were females, a team of experts carried out a rescue mission to raise the eggs in captivity during the breeding season from 2009, and it was hoped that this would mark the start of a long-term captive breeding and conservation programme to not only bring the Falkland diver back from the brink of extinction, It also helps restore wetlands in the area, protecting both wildlife and people.

Listed in the International Union for Conservation of Nature Red List of Threatened Species (IUCN) in 2016 ver 3.1 - critically Endangered (CR).
