The wild rock dove is the ancestor to what is probably our most familiar bird - the feral pigeon, which is often found in large numbers in our towns and cities.

Bell heather is our most familiar heather. In summer, it carpets our heaths, woods and coasts with purple-pink flowers that attract all kinds of nectar-loving insects.

The tiny, grey-brown house mouse is one of our most successful mammals. It thrives around buildings but is less likely to be found in our houses these days due to better construction.
