Question

I recently read about how warmer air decreases lift for airplanes.

I wondered whether birds would also experience reduced lift, and whether that might make it harder for them to migrate long distances. And might that endanger some bird species that take long, arduous migration routes?

Answer 1

Rising temperatures may cause birds to move their wintering grounds northward, potentially leading to resource mismatches and making their migratory journeys more difficult due to reduced lift, endangering some species.

Step-by-step explanation:

The phenomenon of birds shifting their wintering grounds northward in response to rising temperatures presents several concerns. One significant problem could be the potential mismatch between the birds' arrival at their breeding grounds and the availability of critical resources. Birds that travel further north may encounter food sources that are not yet available or breeding habitats that are not yet suitable due to asynchronous seasonal changes.

Furthermore, the increase in average temperatures, attributed to global warming, can decrease lift for flying animals, potentially making long migratory journeys more arduous for birds. As a result, some bird species could face increased risks during migration, which may endanger their populations, especially those with already strenuous migration routes.
