The Striated Heron: A master fisher

The Deception Bay intertidal flats are a birding hotspot in Queensland's Moreton Bay. Known for its international migratory waders and local waterbirds visitors have the opportunity to observe one if its inhabitants, the Striated Heron, foraging in the surrounding mangroves, intertidal flats and gutters.

Deception Bay is part of the Moreton Bay Ramsar Site

Striated herons (Butorides striata) are highly adaptable hunters, particularly skilled at catching fish in intertidal flats. They employ a mix of physical adaptations and learned behaviours that allow them to effectively catch prey in these challenging, shifting environments.

The Striated Heron with its low profile and camouflage is physically adapted to fishing in shallow water.

Physically, striated herons have a compact, stocky body with short legs and toes that help them manoeuvre over mudflats without sinking too deeply. Their sharp, pointed bill and quick reflexes enable precise strikes at fish or crustaceans just below the water's surface. Their cryptic plumage, typically grey or brown, provides camouflage against the mud and water, making it easier for them to approach prey unnoticed.

Behaviourally, striated herons use several hunting techniques that demonstrate impressive adaptability and intelligence. They are known to practice "stand-and-wait" hunting, staying motionless for extended periods before striking at passing fish. They either stand motionless or as can be seen in the video, maintain a crouched position parallel to the waterline, using rocks to remain hidden whilst actively stalking prey by moving slowly and carefully to avoid startling them.
