Owls
I remember coming into work one morning and opening a door to a room only to find an owl flying towards me. Basically it was a room with a inner door, going into another room with an outer door to outside that stays open. Someone had already opened these doors as they had come into work early without my knowledge. The first door was an automatic door, so I walk towards the first automatic door with the intention of opening it, only to find it open automatically followed by something large flying towards me, I ducked as quick as I could as it flew about an inch over the top of my head!

Took about an hour to eventually catch the owl with a rather large fishing net.
