Believe it or not, birds scare me. So there will be no foul at our house! No bats, either--I don't know what category they fall into, but they throw me into a panic attack when they get into our house. I'm getting shivers just thinking about birds. UGH.
No budgies in your house then
Bats are mammals. Most species of bats are among nature's must beneficial critters. They eat hoards of insects, and their droppings, called guano, is among the best fertilizers for cultivated crops. Despite their strange appearance, most bats are quite harmless to humans.
I don't think you would like my house. Parrots rule the roost here. It gets pretty hilarious when they all start talking.
