They're back!

The housemartins arrived last week, overnight I think as I opened the bedroom curtains and they were everywhere on the wing after the early morning insects. All the nests they had built last year immediately occupied, which as it says in the book, they will come back to for 50 years and more ! Tell you what....noisy little so and so's they are at the moment, a case of 'her indoors' giving him what for perhaps ?
