More than half of all bird species are in decline, according to a new global assessment, with deforestation driving sharp falls in populations across the planet. On the eve of a key biodiversity summit in the UAE, scientists have issued a fresh warning about the health of bird populations, with 61 per cent of assessed species now recording declines in their numbers. From Schlegel’s asity in Madagascar to the tail-bobbing northern nightingale-wren in Central America, many bird species have lost habitat to expanding agriculture and human development. Just nine years ago, 44 per cent of assessed bird species had declining populations, according to the red list of endangered species from the International Union for Conservation of Nature (IUCN).
