Fortunately, modern thermal imaging technology not only adds to your skills but also allows in-depth documentation of the migratory groups. If you are looking for a new challenge, read on to see how thermal binoculars like the Pulsar Wildlife Ventex XP35 can offer a new window into the habits of flying night travelers.
Why birds migrate at night
In wild nature, the migration of birds is a natural and cyclical process dictated by the changing seasons. For many species, the only way to survive is by finding more favorable conditions for living, primarily for safe nesting and available food sources.
The nocturnal migrants are usually smaller, land-based birds, such as songbird species – thrushes, warblers, sparrows, ducks, and wading birds, to name a few. Their migration strategy is usually based on a few significant reasons:
- To avoid the diurnal predators like hawks and falcons. With the cover of darkness, smaller birds can use the same high-altitude airways that are occupied by raptors during the daytime.
- To regulate their internal temperature. The cool and calm night air helps the birds to keep their endurance in a sustained flight, which generates a lot of body heat. In addition, the lack of strong turbulence and daytime temperature changes adds to smoother travel and optimal energy reserves.
- To forage efficiently. The daytime is a common time for insectivorous species to find food and replenish their energy after a long night’s flight.
- To navigate their path. Birds’ sensitivity to the Earth’s magnetic field allows them to read the celestial map, navigating their way by the moon and stars.
The aerial journey may take from a few weeks to several months, depending on the species, yet the risk of danger is always high. Isn’t it fascinating that such small creatures can not only overcome hundreds to thousands of kilometers but also come up with such thoughtful strategies?
