East Glamorgan Bird Atlas Published

A culmination of many hours of fieldwork by local BTO volunteers and members of the Glamorgan Bird Club, the East Glamorgan Bird Atlas is now published.

East Glamorgan Bird Atlas

Data from all BTO national atlases and that collected by bird club members has been used to illustrate species distribution maps for both winter and breeding seasons from the 1960s to the present decade. Categories of breeding evidence are shown using a range of symbols, and breeding change maps are offered for 1984 vs 2011. Species richness maps for more than 300 tetrads show the hotspots across the region. Urban areas, rivers and birding sites can be viewed by a simple mouse-click.

Viewers can now see historical losses and gains of our avifauna in a readily accessible, attractive format – for free.  We hope you find the new atlas interesting and informative.

The maps provide much food for thought.  Cuckoo is becoming absent in the south of the region, and likewise, Willow Tit is just clinging on to a few sites in the north. Is the increase in Nightjar attributable to range expansion or observer effort?

These few examples merely scratch the surface of what the atlas is revealing about the changing fortunes of our local avifauna. How can we address these changes locally?
