Its the RSPB Big Garden Birdwatch this weekend. All you need to do to take part is count the number of birds you see in your garden for an hour during the weekend. It runs from the 25th to the 36th of January and helps the RSPB to get an idea of how our birds are faring numbers wise. You can register on the site now and take advantage of the guide if you are not sure what species you are seeing.
