Why does a bird open its beak? This is a very good question. Sometimes I see people open their mouths. And it's not clear why.
This is the Serpent Eagle and lives in Israel.
He is very shy and distrustful. Maybe he opened his beak in surprise.
Maybe he swallowed the snake. I do not know.
birds do not sweat like humans, therefore, by opening their mouths, birds cool their bodies.
This is the correct option.
It's very hot in Israel. I thought. It is good that people do not cool their bodies in this way.
Have a nice day, everyone.
