Birds

The British Trust for Ornithology is asking the great British public to participate in a national study of Tawny Owls and their calling behaviour, by listening out for them this autumn and winter. Tawny Owl populations are thought to be in decline and the species has recently been added to the Amber List of Birds of Conservation Concern.

The UK’s mammals present particular challenges for monitoring; they live in a wide variety of habitats, vary enormously in size and can be very difficult to see, but Britain’s army of volunteer bird surveyors could come to the rescue.
