Does anybody have a reprint of this that they can send me? I am no longer a member of AAAS and am retired, so it is inaccessible to me.
Thanks in advance.

We know that birds are declining globally, but more fine-scale information on population trends is needed to guide conservation efforts. Johnston et al. used participatory data from eBird to track 14 years of population changes across the ranges of 495 birds in North and Central America and the Caribbean. Almost all species showed areas with population increases and areas with declines, often with the strongest declines occurring in areas where species were most abundant. Most species were declining overall, suggesting a worsening situation for birds. However, areas of population increase may offer refuge or point to conditions that could facilitate recovery. —Bianca Lopez
