fowl behaviour

I went to a university that was built around a lake - or rather they built a lake and decided at the same time to build a university. Anyway, the point is that at this university you got to learn about the behaviour of ducks and geese. Not as part of the course of course (aside from perhaps the environmental or biological ones), but you picked up their behavioural habits from being surrounded by them for a few years.

Today while walking to the bus stop the streets were quite quiet and I was approaching a woman from behind. She was walking quickly, but not quite as fast as I was. What I noticed then I found interesting. He reaction to being approached from behind was identical to that of a goose.

She proudly didn't alter her pace, or look behind - essentially trying to appear unperturbed; so far so good. She also however tensed, straightened her back and started making subtle side glances to catch sight of me in her peripheral vision. Not unusual behaviour at all, but very much like that of a goose.

Anyway, I was only walking up behind her because I couldn't cross the road at that point and I immediately crossed after realising I had made her uncomfortable. Poor swiss goose woman.
