This is a scenario we don't often encounter that I just have to share it because the whole thing seemed to be very funny at that time.
Despite having all windows closed, a wonderfully advanced ventilation system, and dust prevention methods using double doors (one remains closed while the other one opens) and the amazing contraption that is known as an air shower, two runaway crows (wingspan at least 12 inches/30 cm across) have managed to weasel their way in and and are now flying around the factory on the first floor area. A badminton net is fixed upon one corner to trap them, and three maintanence staff are assigned to catch those crows before anything terrible happens to either the crows or to the people who are working in that area.
It looks like a hopeless situation, though... the crows are still flying and are going nowhere near the net, they're also avoiding the windows that were thrown open just for them (perhaps they are traumatised by their previous encounter with the windows that would have sent them flying backwards for a bit)
How do you tell a crow that you want to help it get out safely and not hurt it?
Update: The crows have finally been caught and left where they belong. We apparently had to get in a crow expert (and I bet you never guessed they existed), and the whole maintenance team. From where I was, it sounded like cheers and jeers during a particularly exciting football match!
