Some birds can detect much lower frequency sounds that humans can. These sounds are called infrasounds. What is the leading hypothesis for why they are able to detect these low frequnecy sounds?

a. to be able to make quick flight changes to avoid predators that produce infrasounds

b. to detect the orientation of the sun even at night so that they can continue to fly

c. to detect pheromones to identify intraspecific members of the opposite sex during mating

d. to orient themselves during migration by detecting waterfalls, volcanoes and thunderstorms

e. to echolocate prey by producing these infrasounds that then are reflected back to their ears

d. To orient themselves during migration by detecting waterfalls, volcanoes and thunderstorms.

Explanation:

It's known that natural events such as earthquakes, waterfalls/ocean waves, volcanoes and severe storms generate infrasound; the primary hypothesis about why some birds can detect infrasounds is to be able to orient themselves during their migration and avoid such natural events.
