Don't laugh....they're good at it, and nobody really knows how to deal with an angry goose.
I came back from an out-of-town trip late one night and was trying to quietly slip past the gate to my back door without waking anyone up.
The fact that I was sneaking seemed to trigger their response and I suddenly have three large adult geese thumping me with their wing 'knuckles' (if you've been around geese, you know that one), biting and hissing at me and making a huge fuss that woke up the whole house. Even after they recognized me, the geese were still suspicious.
I have a flock of ducks and they are good at sounding the alarm when something is out of the ordinary. If a car pulls in our drive they all scramble to the gate and “discuss” the arrival. At night a cat or anything that disturbs their rest results in a grumbly protest. We are alerted to anything unusual or unexpected that happens.
Uh huh, they smelled Wild Turkey!
