The House Martin's nest was 2/3 there from previous nestings too, another was close to it perhaps a foot away but something destroyed that a couple of years ago, maybe that's why they didn't nest there last year.

I imagine each 'lump' of mud in the nest is a mouthful?

This I got of one flying from the nest, you can see the remains of the other there. They now fly straight in and out without having to squeeze, must have worn it to the correct size!
