This sort of thing can test one's sympathies for Sparrowhawks.
However, one starts to wonder what can be done to make life more difficult for the Sparrowhawk. If the problem persists, I may be tempted to extend the louvres by about 25mm, so that the Swift can get out of danger as quickly as possible.
Fortunately, both Swifts in this box have survived so far.
