Logged forests, climate change driving birds in tropical mountains to higher elevations: Study

Logged forests and climate change are driving birds in tropical mountains to higher elevations. Smaller bird species colonise logged forests better, while larger ones are increasing in primary forests. Logged forests have higher temperatures and lower humidity, pushing birds to higher elevations. Logging can lead to the loss of large-bodied species and decrease biodiversity. Safeguarding primary forests is crucial to mitigate the effects of climate change and allow species to shift their ranges upwards.
