All around the Northern Hemisphere, the evocative call of a curlew is a telltale sign of spring. With their tall, skinny legs and long, curved bills, this group of migratory shorebirds has earned a reputation in many different cultures—but now they’re facing serious threats, and one species is already extinct. Last spring, one man became so concerned about the plight of these iconic birds that he walked for two days across the English countryside inside a giant curlew costume. His name is Matthew Trevelyan, and in his day job he works to protect the pastoral grasslands of Nidderdale, a landscape in Northern England where Eurasian Curlews love to nest. Matthew joins us to talk about his long walk, the challenges facing curlews in the UK and worldwide, and why so many of us find the song of this slender bird to be so moving.
