Our swallows often have later brood, bit worried for them, but they seem to manage ok, main thing here is lack of insect later on, September can be chilly.
I'm thinking house Martin will be about the same?

I think you're right.  They apparently have 2 to 3 broods a year, just like swallows, so perhaps mine will have a successful brood this year, so long as they finish the new nest pronto.
We are squabbling about how best to protect the nest from woodpeckers and possibly rats.
