I now know why Geese make such excellent "Guard Dogs". These ones in Fota Wildlife Park give the impression of being, while not friendly, just more sort of ambivalent about your presence on their territory. Get too close or get distracted by taking a photo (as I did) and you are likely to be pecked. I'm sure that the high-pitched yelp that I let out upon being pecked was very amuzing, not just for my fellow humans but for these feathery creatures too - from whom I will now keep a more respectable distance!
And God said, "Let the water teem with living creatures, and let birds fly above the earth across the expanse of the sky." So God created the great creatures of the sea and every living and moving thing with which the water teems, according to their kinds, and every winged bird according to its kind. And God saw that it was good. (Genesis 1:20-21)
