This weekend it's been the RSPB's Big Garden Birdwatch...
...they claim it's the worlds largest wildlife survey.
You spend one hour noting the number of birds and different species that visit your garden.
During my hour earlier to day I had 10 species visit my feeders.. the last one was a bit special.
Goldcrest (Regulus regulus)
The smallest British bird weighing around 6.5gm.
All the images were taken through my kitchen window... and it was raining.
It's only the second one I've seen in the garden in over 10 years
