Hmm... About that "will they honk at everyone walking on the path next to our yard", I gather from the comments that they will eventually get used to people?
So maybe they'll "warn" for a few months, then stop?
No, geese know who belongs on the premises and who does not.
They imprint. That means they know you, they us, they know our dog, they know who is NOT supposed to be there. They know our cars slowing down on the highway and pulling into our driveway, 350 yards away. They recognize the sound of the engine/tires and they know if the car approaching is NOT one of ours.
They are great watch dogs.
Funny story:
I blew up a photo of DH, and printed it out (like a paper mask) and tapes it to windows & in the bushes for a joke, never thought about how the geese would react to this.

I moved the face around and even taped it to the upstairs bathroom window which was funny cuz whoever it was would have to have a extension ladder to peek in that window..
It was so funny that I printed out an Elvis face and the Queen Mum face & taped them here & there, in the bushes, in the barn. It was hysterical seeing Elvis in the bushes..........
THE GEESE WENT BALLISTIC that there was a stranger in the bushes !!!
When I taped the DH face to the front door window, the geese stood there all day, trying to get on the front porch, waiting for him to come out and give them treats.
The moral of the story it:
If you raise them, they know you, your car, your voice.
If you are kind, they love you, if you are cruel, they will hate you.
Our geese are part of our family just as our LGDs are...............the geese' job is to mow the grass and do their watching. They intimidate crows, hawks and Eagles, and more than likely other predators as well.
They have excellent eyesight, seeing things in the sky and underbrush. They work together with the LGDs and sound the alarm if they see anything threatening.
Another note:
Visitors here will always walk up to our LGDs and offer a hand for the dogs to sniff and I have to race to stop them, the dog will bite you !!
he is so fluffy and cute that people just think he is a big puppy. WRONG.
But they will NOT even get out of their car if the geese are out there.
Terrified of geese !

Nobody can just drive in here & go snooping around without the geese letting us know.
I love them.
