In many modern cities, the lush greenery lining streets and parks may look like a symbol of urban eco-consciousness. But ecologists and ornithologists warn that these trees, often non-native species imported for aesthetics or fast growth, are having unintended consequences on urban wildlife — especially birds. Birds rely on specific native trees for food, shelter, and nesting. When unfamiliar species are planted, especially those that don’t support local insects or fruit cycles, birds become disoriented, sometimes skipping cities entirely during migration or failing to find enough nourishment during breeding seasons.

 The mismatch between urban landscaping and local ecosystems is subtly reshaping bird behavior, leading to long-term impacts on biodiversity. Experts urge city planners to prioritize native flora to preserve the natural balance between greenery and wildlife.
