Bird Migration and the Equinoxes: Birds And The Equinox: A Celestial Connection
Bird migration is a fascinating natural phenomenon, and the equinoxes play a crucial role in triggering these long journeys. The equinoxes, occurring twice a year, mark the time when the sun is directly over the equator, resulting in equal day and night hours across the globe.
These events trigger a cascade of changes in the environment, including shifts in day length and solar angles, which act as powerful cues for migratory birds.
The Influence of Day Length and Solar Angles
The changing day length and solar angles are the primary environmental cues that influence bird migration timing. As the days grow longer in spring, birds sense this increase in daylight hours and begin their journey northwards to breeding grounds. Conversely, as days shorten in autumn, birds sense the decrease in daylight hours and embark on their southward migration to warmer wintering grounds.
The angle of the sun also plays a significant role. As the sun’s angle changes throughout the year, it affects the amount of sunlight reaching the Earth’s surface, impacting temperature and food availability. Birds utilize these cues to navigate their migratory routes and determine the optimal time for their journeys.
Bird Species and Migratory Routes
Numerous bird species undertake remarkable migrations, often coinciding with the equinoxes.
