Two species competing for the same resource can avoid competition and can coexist by resource partitioning.

Resource partitioning among warblers enables coexistence by utilising distinct niches. Blackburnian Warblers dominate the upper canopy, while Black-throated Green Warblers forage in mid-level branches. Yellow Warblers glean insects from foliage, while Black-and-white Warblers spiral around trunks. Northern Parulas favor dense foliage near water sources. Each species specialises in different foraging techniques, prey types, and microhabitats, reducing direct competition. This allows them to share the same ecosystem without exhausting resources or displacing one another.
