What could that be?


Anti-pigeon spikes?

Designed to deter them from perching, nesting and generally making a
mess of buildings and people. In this case, bus shelters and bus
passengers. Often also seen atop passenger information systems in
railway stations.


This was something different -- this looked like a small ball with
different colours and spikes protruding from it.

I have seen anti-pigeon spikes normally around the edges of buildings or
in the lower parts of bridges.
