 Parenting on the move is all about sacrifice. 

 

 

 

And in the forests of northeastern Australia, another great journey spurred by parental¹ dedication² is about to begin. On translucent³ tawny⁴ wings, a little red flying fox flaps homeward after a night of intense foraging⁵. And she is one of millions. 

 

 

 

Somehow, she finds her pup in the din⁶ of the camp. She wraps him in her nursing embrace. He needs calcium⁷ from her milk to build flimsy bones. And he's leaching⁸ it away from her own fragile flying machinery⁹ at an alarming rate. 

 

 

 

The bats have eaten through the calcium and energy-rich eucalyptus¹⁰ blossoms for miles around. The situation is getting desperate, the need to move intense.
