- Crunch time for saving environment on farmland April 18, 2018As the debate on the next EU budget draws to a close, will Budget Commissioner Oettinger dedicate enough to the environment and climate in the future Common Agricultural Policy (CAP) to avert disaster? Biodiversity is in freefall in Europe. Stories of the collapse of insects and birds, mostly related to intensive agriculture, have been hitting […]
- How do we spread word about the biodiversity crisis? Experts weigh in. April 16, 2018How do we raise awareness about the biodiversity crisis facing the world? This was the problem put to six experts (including Sir David Attenborough) at a panel held at BirdLife’s Cambridge office, the Cambridge Conservation Initiative, on 12 April. It’s a tough one. Right now, species are going extinct at a rate up to 1,000 […]
- “The world has cause for optimism”: Sir David Attenborough’s keynote speech April 13, 2018Biodiversity loss is a huge problem for the conservation community. Not only are extinctions occurring at a rate up to 1,000 times normal levels, but public awareness about this crisis is lagging far behind that of other environmental issues such as climate change. It was precisely to address this problem that the Godfather of modern […]

When this species was uplisted from Least Concern to Vulnerable in the 2009 Red List update, there was some evidence to suggest that declines may have exceeded a rate of 50% during the past three generations or 45 years (Beilfuss et al. 2007), but data were regarded as patchy and an overall decline of 30-49% was considered a more reasonable estimate. Overall estimates suggest that the species’s global population has declined from over 100,000 individuals in 1985 to 50,000-64,000 individuals in 2004 (Beilfuss et al. 2007). This implies that the species may have declined by over 50% in 19 years, and when these data are extrapolated to a period of 45 years in the past (1967-2012) or past and future (1985-2030), assuming an exponential trend, the calculated rate of decline is c.65-80%.
