As I walked towards the garage first thing this morning, I spooked a wren fledgling that had been hunting for insects by the wheely bin. It tried to fly over the garage roof, but couldn’t gain enough height, and crashed into the coal-hole door. It then flew off low, past the garage and outhouse, and disappeared into a crack in the drystone wall by the compost heap.
I wouldn’t mind betting the wren hatched in a nest somewhere very near its hiding place. We often see wrens by the compost heap. Rotting fruit and veg attract insects, and insects attract wrens.
