Mark Avery is a scientist by training and a naturalist by inclination. He worked for the UK's Royal Society for the Protection of Birds for 25 years - for the last 12 of those as its Conservation Director. As a senior figure in UK nature conservation Mark played a part in buying land for nature reserves, projects to reintroduce threatened species and campaigning to change government policy on farming, fisheries, forestry and energy production.
Mark's latest book, published by Bloomsbury, is A Message from Martha: the extinction of the Passenger Pigeon and its relevance today.
Mark says 'I love the natural world. In my writing I aim to describe its beauty and stand up for it when it is under threat. The world of nature needs all the help it can get'.
Mark writes a daily blog about UK wildlife issues at www.markavery.info/blog/
