The 2018 Big Garden Birdwatch is upon us. Run by the RSPB it takes place over three days between 27th-29th January. All you need to do is spend one hour watching the birds in the garden, park or even supermarket carpark and record the different species that you see.
You can download a free pack with all the details that you need, plus some great information about how you can help birds and other wildlife, from the RSPB here. The recording is for the UK only, but the information pack will be useful for other parts of the World too, and it is an enjoyable thing to do just for the heck of it.
