The document discusses the decline of the curlew population in the UK. It notes that the UK population has declined by nearly half in the last 20 years, with a loss of 5,500 birds per year. Various factors are contributing to this decline, including loss of habitat due to agriculture, forestry, and increasing urbanization. Larger farm sizes and more intensive farming practices are also negatively impacting curlew populations. Two poems are included that express the beauty of the curlew call but also the loss that would come from their disappearance.
