An ornithologist tracks a bird species that reduces its migration distance by 15% due to favorable winds. If the original migration distance was 5,000 kilometers, what is the new distance?

**How Climate Shifts Are Shortening Bird Migrations—And What It Means for Nature** Why are birdwatchers noticing shorter flights? A recent study by an ornithologist reveals an unexpected pattern: a species once known for its long, continent-spanning migration is now completing its journey 15% farther north in just a few seasons. What’s behind this shift, and why should we pay attention? With changing weather patterns across North America, some bird populations are adapting unexpectedly. Favorable winds now allow longer-range movements, prompting scientists to reevaluate traditional migration routes. This phenomenon isn’t isolated—it reflects broader trends tied to climate, habitat, and energy-efficient flight strategies. Understanding these shifts offers valuable insight into how wildlife responds to environmental change. An ornithologist tracks a bird species that reduces its migration distance by 15% due to favorable winds. If the original migration distance was 5,000 kilometers, the new distance measures not just miles saved—but a subtle yet significant reorientation of natural movement. The birds now cover approximately 4,250 kilometers, reflecting a refined, energy-conscious travel pattern shaped by current atmospheric conditions.
