We have Sparrows in a nest box with young and saw the Female with a mouthfull on her way back to the Nest.
As well as the Spider (or possibly a Crane Fly), it looks like she’s got a few other bugs in there including what looks like at least one Wasp or Hover Fly.
The young have been noisy and are sounding more like grown birds now, I’m pretty sure they’ll be out and about soon.
