	abstract = {We present a general framework for characterizing the ecological and
	societal consequences of biodiversity loss and applying it to the
	global avifauna. To investigate the potential ecological consequences
	of avian declines, we developed comprehensive databases of the status
	and functional roles of birds and a stochastic model for forecasting
	change. Overall, 21% of bird species are currently extinction-prone
	and 6.5% are functionally extinct, contributing negligibly to ecosystem
	processes. We show that a quarter or more of frugivorous and omnivorous
	species and one-third or more of herbivorous, piscivorous, and scavenger
	species are extinction-prone. Furthermore, our projections indicate
	that by 2100, 6-14% of all bird species will be extinct, and 7-25%
	(28-56% on oceanic islands) will be functionally extinct. Important
	ecosystem processes, particularly decomposition, pollination, and
	seed dispersal, will likely decline as a result.},
