Birds sneak through narrow slots like fighters

The sight of an angled flying tern to sneak through the door of the warehouse at speeds of up to 56 km / h has been recorded in Scotland.

The incident happened on a farm in Angus Glens, Scotland. The tern - with a wingspan of about 36 cm - is flying back to the nest in the farm's warehouse and meets two half-closed doors. Without hesitation, it flapped its wings and tilted its body to squeeze through the narrow gap (about 5 cm wide). The bird flew through the slot without touching any doors. Keith Ringland, a natural photographer, was fortunate to capture the moment of ecstasy from a nearby barn.

The above tern is in a breeding period on the farm. Ringland believes that he regularly flies through the door with such tremendous speed. It usually escapes from the warehouse with some big holes in the house forever. According to Ringland, when returning to the warehouse the bird could not fly through the hole in the roof at high speed. So the narrow gap between the two doors became its favorite entrance.

There is also another reason. " There is also a mother swallow in the warehouse. Two birds fly away with holes in the roof and return through the doorway. Perhaps it is an agreement between them. Without such a convention, the possibility collisions will happen when a child flies away and the other returns with a door ", Ringland explained.

Swallow (or swallow) is a bird that adapts to the predatory life in the air thanks to its slender, slender body and long wings. They have the ability to catch bugs while flying. Swallow using a V-shaped tail to change direction suddenly and keep balance in the air to catch prey.
