Swallow......

Swallows: Here his wife is injured and the condition is fatal.
She was hit by a car as she swooped low across the road.

Here he brought her food and attended to her with love and compassion.

He brought her food again but was shocked to find her dead.
He tried to move her....a rarely-seen effort for swallows!

Aware that his sweetheart is dead and will never come back to him again,
he cries with adoring love.

He stood beside her, saddened of her death.

Finally aware that she would never return to him, he
stood beside her body with sadness and sorrow.

And many people think animals don't have a brain or feelings
