Masked Duck vs Black-headed Duck: common questions

Which duck is harder to find in the wild?

The masked duck is, spending nearly all its time hidden within dense marsh vegetation, while the black-headed duck, though secretive about its eggs, is not specifically known for hiding itself the same way.

The black-headed duck does, as the only duck species known to be an obligate brood parasite, laying all its eggs in the nests of other birds rather than raising young directly, unlike the masked duck.

What do these two ducks have in common?

Both are Least Concern ducks of South American wetlands known for unconventional survival strategies, whether through extreme secrecy or an unusual reproductive approach, rather than striking plumage alone.
