Although it looks like a nest it’s actually a disease in the tree called “witches broom” that causes it to grow like that, a bit like a plant cancer that can spread from one plant to another and these are the equivalent of tumors. There can be one or many small ones or sometimes a giant one like this
If you see trees absolutely covered in hap hazard looking in ‘nests’ year round but never any birds using them then it’s more likely you’re actually looking at witches broom
Rooks!
I’m living in Roscommon and all the trees around me look like this, and there’s hundreds of rooks in them. Beautiful sight when a car beeps or something and they all take off flying to a neighbouring bunch of trees.

That’s Jimmy’s spot he rents it out for 900 a month leave him off
€900 a month
It’s called epicormic growth. This looks like a common lime, tillia X europaea. They do this all the time. It’s basically just the tree throwing out a tonne of smaller, weaker branches in the middle, usually as a kind of panic reaction to being cut or attacked in some way, but these limes will do it all the time for no reason
Maybe its a wildlife HMO, their neighbours hate them

Even the birds have solved the housing crisis.
