I was so pleased to see a nuthatch on the feeders early today, but the light was really terrible for photography. Around lunch time there was a bang on the patio doors, and I found this nuthatch on the step outside. It seemed stunned and it was half an hour before it recovered and flew away. Then at about 5:30pm there was a repeat performance, though this time it lay on its back for at least 10 minutes before righting itself and eventually flying away.
