Hello All,

Is there any effort to release these trapped birds? What happens to birds
that get trapped in large buildings or stores like this? Does anyone know?

At Manchester international airport in the UK there is what seems to be a
small population of House Sparrows living in the main terminal building.
They seem quite content, nice and warm, no raptors, cats or other predators.
Last time I was passing through the airport they seemed to be enjoying a
morsel of food that somebody had dropped.

All the best,
