[short story about a heron]
My family home had a man-made pond.
We became pretty accustomed to having to fend off herons from eating the fish. To protect them, we installed a net around the pond.
Eventually a heron somehow managed to get through the net but soon realised he was trapped and repeatedly flew into the net, injuring himself in the process. He escaped but did himself a fair bit of damage.
Anyway, it turns out heron blood has the same colour and consistency as red paint (photo here for those interested).
Needless to say the poor guy never returned.
