Older Whales Sing Better and Father More Offspring

Quick Smiles:

• Older male humpback whales excel at singing, boosting their mating success.
• Populations rebound above pre-whaling levels, revealing new behaviors.
• Advanced tech uncovers paternity and age from tiny skin samples.

New research reveals older male humpback whales outperform younger rivals in mating thanks to refined singing skills.

As populations recover post-whaling, females grow more selective, favoring experienced singers who sire more calves.

The Sea Mammal Research Unit at the University of St Andrews analyzed two decades of data from New Caledonia breeding grounds.

Early recovery featured young males dominating, but older whales now thrive as numbers rise.

Male humpback whales produce the animal kingdom’s most elaborate songs, heard across breeding areas.

“As the population recovered, there were more older males than expected singing, escorting females, and successfully fathering calves compared to younger animals,” said senior author Dr. Ellen Garland.

“It is only now, as whale populations recover and new analytical tools become available, that we are beginning to understand how far-reaching the consequences of whaling truly are,” said lead author Dr. Franca Eichenberger.

The impacts extend beyond population size—they shape behavior, competition, and reproduction as whales continue evolving.
