Any idea how to get a pigeon or dove out of my huge church with sky high ceilings? [View all]

I think he may have come in the church last Saturday after a huge wedding had just taken place. He may be one of those that are purchased for such events.

Anyway its been a week and he is known to swoop around in the middle of Mass and makes really loud pigeon cooing sounds from the choir loft.

I feel so sorry for him - any ideas?
