Scientists have long suspected that some species of birds can eat drink, mate and even sleep while flying, but even they were stunned when data showed that one such species could go up to 10 months without landing.
As its name suggests, the commons swift (Apus apus) is a common bird that lives all across Europe and much of Asia, but their flight time is anything but common. This medium-sized bird currently holds the record for the most time spent in the air per year, with data showing that some specimens can spend up to 10 months out of 12 without landing even once. They drink and eat in the air, feasting on any insects that they can capture in flight, they can mate in the air as well, and, like the much larger frigate birds, they can also sleep in the air by gliding on warm air currents known as “thermals”.
