- In some ways, whistling-ducks act more like swans than ducks. The male helps to take care of the offspring and a mated pair stays bonded for many years.
- Pesticides applied to rice in the 1960s caused declines in Texas and Louisiana populations. Numbers have recovered and stabilized since then.
- The Fulvous Whistling-Duck is a frequent nest parasite, laying eggs in other Fulvous Whistling-Duck nests, as well as the nests of other duck species. These other duck species often lay their eggs in Fulvous Whistling-Duck nests as well.
- Unlike many other ducks which have elaborate courtship displays, whistling-ducks appear to have none.
- Other than in agricultural habitats, the Fulvous Whistling-Duck nests only rarely in the United States. It started breeding in the United States only in the late 19th and early 20th centuries, nesting in rice fields.
- The oldest recorded Fulvous Whistling-Duck was a male, and at least 11 years, 2 months old when he was shot in Cuba in 2004. He had been banded in Florida in 1993.

There is little information on Fulvous Whistling-Duck population size, but according to the North American Breeding Bird Survey, numbers on the continent remained stable between 1966 and 2015. The species rates an 8 out of 20 on the Continental Concern Score. Fulvous Whistling-Duck is not on the 2016 State of North America's Birds' Watch List. Pesticide exposure may pose a risk to these ducks because of their close association with agriculture.
