avión común common house martin (Delichon urbicum)

The book I was reading made a point of explaining it, "los aviones comunes (una especie de ave) chirriaban", which I thought was funny. I guess, if you don't know that this type of avión is a swallow and not an airplane....
It's a bird, it's a plane, it's a.... house martin!

"Sir, you are not allowed to board the swallow without a boarding pass..."

poalanca shadoof

You're telling me the English isn't a comic book sound effect?

Now you've got me imagining that shadoof is the sound of dropping a bucket into the well and then dumping the bucket of water into another container. Sha when you drop the bucket down the well, doof when you raise it and dump the water out. Shadoof, shadoof, shadoof.
It's actually from Arabic شادوف‎ though.
