Wah Chan’s image of a Black-crowned Night-heron (Nycticorax nyctic) using a stick to stir the water is probably another example of a heron making use of a tool to bait fish
Herons are known to use tools that include live insects, fruits, discarded crackers and even twigs that they cast into the water to bait birds LINK.
It has also been reported that herons also indulge in tool manufacturing, trimming oversized twigs to a smaller size LINK Young herons tend to use larger twigs and thus less successful in baiting fish.
