Last month the pigeons were puffed against the cold.

Month, moth, munch is how it sounds when your teeth are chattering.

The way you know it's cold is the pigeons know it –

pigeons have pigeon ways of knowing things,

were there some other way of knowing, they would know that too.

Puffed is warm and uses all their natural advantages.

Against the ledge, under the overhang,

the cold sometimes takes a while to find them –

cold is determined, though, and always finds them anyway.
