Where there’s smoke, there is fire. But with climate change, larger and longer-burning wildfires are sending smoke farther from their source, often to places that are unaccustomed to the exposure.

Tropical forest birds, which tend to have wings that are short and round relative to their body length and shape, are more sensitive to habitat fragmentation than the long, slender-winged species common in temperate forests, according to an international collaboration that included scientists from Oregon State University.
