Children can buy an RSPB-approved garden bird feeder (pound;4 each) and bird food from participating branches of Tesco.
One success story comes from Inverteign School at Teignmouth, Devon, where the cirl bunting is still found. The RSPB believes no more than 700 of the birds survive, blaming changes in farming practice for destroying the bird's winter foodstuffs.
Last winter the school fed cirl buntings in its grounds, on feed donated by a local supplier, and pupils were able not only to monitor the birds but also to preserve lives.
