Anti-pigeon defences

And now for something completely different: anti-pigeon defences.

Pigeons can get everywhere, making nests, leaving droppings. These ones seem very interested in the next trains from Caulfield.

It’s probably gone mostly unnoticed, but over the past few years, various methods to prevent them roosting have become commonplace.

In the case of Caulfield station, they’ve put in a lot of netting that cordons off parts of the platform roof areas, including the tops of the signs. (I haven’t checked if they’ve fitted the sign above, which is in the subway.)

Solar-powered road signs now often have spiky bits on them, as do increasing numbers of shop signs, including big ones like this. (I think it looks a little odd up close.)

On this building in Centre Road, Bentleigh, there are fake owls around the top. I’m not sure how effective they are.

But despite these methods, sometimes the pigeons still win.
