The Scottish Seabird Centre at North Berwick. This was extensively refurbished - with a new, interactive, discovery centre in 2019, and this was my first visit since then.

The seated seabird is, I think, an arctic tern, judging by the profile, especially the tail. [Sterna paradisaea - and probably the most travelled of migrating birds]
Although, given the Bass Rock in the background I was expecting it to be a gannet or a kittiwake.
