and amphibians.
Distribution and habitat
The yellow bittern's breeding habitat is reed beds. They nest on platforms of reeds in shrubs. Four to six eggs are laid. They can be difficult to see, given their skulking lifestyle and reed bed habitat, but tend to fly fairly frequently, when the striking contrast between the black flight feathers and the otherwise yellowish plumage makes them unmistakable.
Conservation
The yellow bittern is protected under the Migratory Bird Treaty Act of 1918.
