To understand this, the team used a video camera which would tell them how the bumblebee’s wings beat at such heights with thinner air and lower oxygen levels.

They thought that bees would either need to beat their wings faster to keep their bodies afloat to adjust to this kind of change. But again, they were taken by a surprise.

Instead of beating the wings faster, the bees increased the angle at which they extended their wings with each beat, reaching closer to their heads and abdomens each time. This action increased the amount of air that they swooped, helping to boost their bodies up. How clever of them, isn't it?

Infact, scientists also found out that some bumblebees have already been living above 4,000 metres for long periods when they discovered a bumblebee nest at 4,400 metres in the Hengduan Mountains in China.

But if bumblebees can fly that high why don’t we see them very often at higher elevations? There is a reason for that! While they may not be limited by their ability to fly when looking for places to settle their colonies, other factors such as the availability of food (flower nectar that they feed on) may be an important consideration.
