Human-made landscape promotes coexistence of two normally separated Andean warblers

(Laboratory of Behavioral Ecology and Evolution at Seoul National University) In the mountains of world, species adapt to habitats in specific elevation zones that do not overlap with other species' elevation zones. Polish ornithologists, following the old traditions of Polish ornithology in South America, discovered that two Andean warbler species that typically occur at different elevations and hunt by tricking insects to escape can co-occur at the same elevation due to fragmentation of tropical montane forests caused by humans.
