On a recent trip to the wood I spotted this blue tit wrestling with some potential nest material. The pink thread was caught on a branch and the bird was struggling to get it free.
The thread looked like it had snagged from a walkers coat and the blue tit had spotted something with which to line the nest. It wasn’t going to let this find go and pulled and pulled.
Somewhere in the woods there is a nest with a lovely pink thread running through it as the blue tit did finally pull it free. I did think at one point the bird was standing on it and causing its own problems.
