Conservation of Birds—Based on Bridget Strutchbury's 'Silence of the Songbirds'
On a broad, planetary scope, birds face a variety of threats, such as climate change, habitat deforestation, and degradation and other human impacts, such as the impact of pesticides. Since many birds migrate long distances, conservation efforts become more difficult. For instance many Cliff Swallows summer in North America (the neoartic) and winter in South America (the neotropic) realm. Therefore the diversity of ecosystems that need protection for the sake of their survival are great.
