The BBC has this wonderful story about a regular gathering of caged birds in Singapore:
"I asked how much the birds were selling for, to be told that this was less a marketplace and more... he thought about the words... a conference of birds.
Every Sunday morning, the birds were brought down from their tower-block eyries so that they could talk to one another.
I had never really thought of birds in that way, but looking again at the rows of cages with birds chatting animatedly, I realised they were doing just the same as their owners, relishing a respite from a solitary life."
