BTO Atlas
09th July 2011
as the Atlas reaches its closing stages, it is extremely important to try and upgrade breeding codes. July is a good month to see fledged young and the image attached is a typical example showing an adult Willow Warbler feeding a brood of chicks. Though it can be easy to establish breeding birds present and probably breeding, actual confirmed breeding can sometimes be more difficult to prove. Please make a special effort at this final stage.
