Conference hears concerns over threatened waders and dwindling wildfowl

National concerns over how to protect breeding populations of wading birds and local worries about dwindling numbers of winter wildfowl featured at the 2023 Hertfordshire Bird Conference.

More than 80 HNHS / Herts Bird Club members and guests learned how the British Trust for Ornithology (BTO) is supporting efforts to halt an alarming reduction in the number of Curlews and other internationally important breeding populations of wading birds in Britain. 

They also heard from Josh Kalms of the Hertfordshire & Middlesex Wildlife Trust about the bird life of Stocker's Lake near Rickmansworth, including signs of 'short-stopping' where fewer winter wildfowl cross from the continent. Anyone who missed the conference, or would like to watch the main presentations again, will find video links posted below.
