Your afraid of a wee bird

They are all bluster & utterly toothless, & understandably get a bit territorial during nesting (don't we all), Isn't that a good thing? to scare off your snakes. In all the years I've had them, I've never been beaked, too be honest they tend to be scared of me, except during nesting. Like most animals if you raise them from chicks, you might even be able to hug them.
They know where they should not be, occasionally sneaking into a neighboring field, as soon as they see me they quickly go back home, probably because they know I may trim 1 wing of feathers for their poor behavior, stops them from flying over the fence, only have to trim a few offenders. I did have a nasty small rooster once that would attack you from behind, & I don't push my luck with my old tusked boar.
The geese look like dinosaurs the way they walk with 2 legs, & attract a lot of bird life from the neighboring wetland, I get spoonbills, white herons, egrets, plovers, teals, black swans & ducks coming in to join them in the winter/spring ponds.
