Today I saw a pair of bt close to the patio box sharing a bit of time together in the rare sunshine. One flew to the feeders and the other popped into the box for a bit of a spring clean. There are feathers in the box at the moment probably from a fight I didn't witness the other day. So hopefully this is the female who will build a nest soon. So I will be studying the neck marking in my bid to tell Mr and Mrs apart before nesting.
Dust if you must but wouldn't it be better To watch the birds ...........
