You can see two different species here, a Painted Stork and a camp of bats, two species which would be perhaps labelled completely opposite to each other with very few similarities.
The bats are night dwellers, the Stork is not nocturnal.
The bats mammals, Stork a bird.
The bats sleep upside down, Stork upright.
The dark bodies of the bats, the vibrant Stork.
Lot more differences, but that's not the point.
The contrast is also apparent in the photograph - bats among the dark leaves in shade, Stork in the Sun. Bats in the camp, lone Stork. But that's not the point either - that's situational.
The situational similarity - both sleeping is what I want to highlight. It is indeed an activity common to all larger lifeforms. It is also associated with concepts like 'home' and 'trust'. The fact that they practically use the same bamboo tree as their homes shows trust among species. Despite all differences, all kinds of them, they can coexist.
Same is the story for plenty of other lifeforms. Every life is a child of Nature on earth. That's what we all share together, with ourselves and every other lifeform.
Amazing, isn't it.
