Death Stalks the Nursery

From the title it would seem that I have been watching too many Poirot films recently.  But observe mes amis the rump of a great tit sticking out of the nest box.  Observe aussi the extreme nearness of the scaffolding.  Then - quelle horreur! - a cat on the scaffolding.  I chased her off, of course, but she'll be back.  And her Siamese pal.

The lady over the wall is having a lot of work done, and asked if I would mind a bit of scaffolding in my garden.  I said of course I wouldn't; but I didn't know exactly where the scaffolding would go.  And I didn't know that the nest box, which the birds have all been turning their beaks up at, would suddenly become a desirable residence.

Despite the scaffolding and the cats, the parents are still feeding the babies.  I think I shall have to throw myself on the mercy of my neighbour.  She actually has been very good in keeping us informed and has even sent M&S gift cards to those of us most affected by her building work.  I'll ask if there's any possibility that the bricklayers can stay away from my side of the wall for a week or two till the nestlings have fledged; and can I put something on the scaffolding to deter cats: a loaded shotgun springs to mind, but perhaps not!
