Brown-bellied stipplethroat

This bird looks just as scared as anyone about the effects of climate change. It’s a brown-bellied stipplethroat, and the average body mass of this species has dropped nearly 6% in the last 40 years. At the same time, as is the case with many of the surveyed birds, its wing length increased. The team will continue to work on the connection between these factors in the years ahead, trying to pin down the complex processes that have led to these changes.
