kondo: hammerkop (a medium-sized wading bird)
Crickets rejoice when the hammerkop loses his eye.
The hammerkop’s diet consists primarily of frogs, tadpoles, small fish, crustaceans, worms, and insects. When fishing, the bird stares into the water with its head angled, searching, looking first with one eye then the other (hence the reference to one eye).
When a superior or someone who is feared is away, the subordinates feel relieved and sometimes take advantage of the circumstances.
