During the winters’ of 2012/13 and 2013/14, thousands of volunteer birdwatchers will be taking part in the BTO’s Wintering Thrushes Survey. BTO Corporate Members are supporting their efforts looking at how thrushes use the countryside throughout the winter; providing the evidence needed to assess the importance of the UK for the five wintering thrush species.
Corporate Members
We are tremendously grateful for all the support we receive from our Corporate Members. Many are involved in specific projects while others help to promote the BTO while supporting the annual Corporate Membership Project through their subscription.

Recent projects benefiting from support
In June 2011, the BTO embarked on a ground-breaking Cuckoo Satellite-Tracking project to determine their stop-over points, migration routes and wintering grounds. This project has been generously supported by Essex & Suffolk Water and Opticron.
The project was initiated using the proceeds raised through the 2010 BTO Winter Raffle which was very generously supported by the BirdWatching & Wildlife Club (BWWC)/Grant Arms Hotel and Carl Zeiss Ltd.
The 2010 Garden Nesting Survey asked people to check their gardens for nesting activity by birds, and the responses have revealed a fascinating picture of the birds that use our gardens for nesting. The participation of thousands of BTO volunteers was supported by Gardenature and the John Spedan Lewis Foundation
Between 2007 and 2011 tens of thousands of volunteer birdwatchers recorded in the winter and breeding seasons for Bird Atlas 2007-11. All areas and habitats were covered, from villages, towns farmland and fens to remote mountains and far-flung islands. This stock-take of our birds is already revealing fascinating changes in the status of our birds and will shape the direction of conservation action over the coming decades.
The Nightingale population declined by a staggering 53% between 1995 - 2008 (Breeding Bird Survey Data) and the emerging picture from Bird Atlas 2007-11 indicates that their range is continuing to contract towards the extreme south-east of England, despite massive, local conservation efforts in traditional coppice and scrub habitats.
Thirteen years on from the last dedicated Nightingale Survey it is time to relook at what is happening to this popular songster and run another survey in 2012. Maintaining high quality habitat in these core areas will be crucial if the species is to survive as a breeding bird in Britain.
