Garden Health Indicator
Birds are sensitive to environmental changes, so their presence—or absence—can signal your garden’s overall health. A steady chorus of robins and wrens indicates clean water sources, abundant insects, and healthy plant cover. When I noticed fewer warblers in my yard, I realized that an overuse of mulch had reduced insect habitat, prompting me to leave some bare soil patches for ground-nesters.
By tuning into those population shifts, you can spot early signs of pesticide overuse, pollution, or habitat loss—giving you the chance to correct course before major issues arise.
