Squeaky Gate II

Last year we had a wee Dunnock that sat on our fence and protested very loudly if either our two cats were visible that included them just looking out of the window. Anyway the protest sounded like someone opening and closing a squeaky iron gate repeatedly which was equivalent to finger nails on a blackboard.
Well, I'm not sure if this is the same wee bird but this one also sits on the fence and sounds like it needs a serious bit of lubrication. Where are those earplugs?
