Tips for herons, egrets and other fishing birds:
- netting over the pond
- chimney flue in the bottom of the pond
- put in an electric fido shock fence
- a motion activated sprinkler
- Migratory Bird Act forbids lethal methods,
heavy fines and jail time take away from pond time ;-)

good luck!
kathy :-)
