What is the feeding strategy of the striated heron?

• A. Standing still and quickly striking at fish with its bill
• B. Foraging while hopping
• C. Probing in mud for invertebrates
• D. Catching prey while flying

Answer: (A)

The feeding style being tested is sit-and-wait ambush predation in shallow water, where the bird stays still or moves very slowly and then lunges quickly with a swift bill strike to catch prey. Striated herons rely on keen sight and a rapid, precise jab to seize small fish or aquatic organisms just beneath the surface, minimizing energy use while maximizing success in their watery habitat. This isn’t about hopping around to search for food, which some other waders do by moving in short bursts. It also isn’t about probing the mud with the bill to root out invertebrates, a method more typical of birds that feed by digging. And it isn’t about catching prey in flight, which is behavior seen in species that chase airborne prey. So the quick, surface-to-subsurface strike from a largely stationary or slow-wading stance best describes how the striated heron feeds.
