There's a bird camping next to the beehive entrance. It steals forager bees when they come out, runs off, then comes back and steals another one.
And here I was going to put a hive next to my house too, since I have wasps. Bees are rather docile, but territorial: they'll attack wasps. Wasps are also idiots and will try to invade the hive to steal honey. Lavender and peppermint fields will give my bees stuff to protect... but will birds start nesting in my trees and stealing all my bees too?
Every time I think I've bent nature to my will, something eats it.
