Join us live online for the RSPB's Big Garden Birdwatch

Are you taking part in the RSPB's Big Garden Birdwatch this weekend? Join us on Saturday from 1-2pm to share your bird-spotting experiences and follow our top birders, including the RSPB team , the BBC's wildlife expert Stephen Moss , TV naturalist Nick Baker and the environmentguardian.co.uk team. Our team will be tweeting their garden bird sightings from around the UK - they kick off at 1pm, so just bookmark this page and come back then. We'd love to hear what you're seeing in your garden, from common house sparrows to rarer species such as waxwings , so post your sightings and questions in the comments below. You can also share your garden bird photos on our Flickr group , find out from the RSPB's Mark Avery why the birdwatch is so important, and - to help you identify some of the most common visitors - see our gallery of garden birds .
