Love and Sorrow

Here a female mate is injured and the condition is soon fatal. She was hit by a car as she swooped low across the road

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

Finally aware she would never return to him, he stood beside her body with sadness and sorrow. And many people think animals don't have brains or feelings?
