In more depressing bird news, researchers at my alma mater estimate that up to 30 percent of all land-dwelling bird species could be extinct by 2100 as a result of global climate change. The study, published this week in the journal Conservation Biology ($ub. req’d), modeled bird population responses to changes in vegetation for over 8,000 species and 60 scenarios, and is one of the first analyses of extinction rates to incorporate information from the recent IPCC reports. I think I’m going to go cry now.
