The article offers information on the observations suggesting movement of humpback whales using its front flippers to move toward its prey. It mentions use of wildlife tagging technology which uses sensors to measure and record videos of a whale's position, speed and acceleration. It mentions capturing of unusual propulsion and sprinting techniques to catch its prey.

Focuses on the discoveries about songs and feeding habits of humpback whales done by researchers in the U.S. Characteristic features of the whale song composition; Indications of the changes in the songs of different years observed from underwater recordings; Structure of the songs; Analysis of the purpose of whale songs; Evaluation of whale intelligence on the basis of clever feeding behavior.

The article discusses research published in the April 2013 journal "Science" into social learning in animals, focusing on the feeding behaviors of humpback whales and vervet monkeys. Animal culture, skill learning, and researcher and cognitive biologist Andrew Whiten are mentioned, as well as marine biologist Luke Rendell and whales' lobtail feeding techniques.

The article discusses two studies in the April 26, 2013 issue of "Science" magazine reporting on social learning in whales and monkeys. Topics include research by Andrew Whiten of the University of St. Andrews in Scotland, and colleagues investigating social learning in vervet monkeys, research by Luke Rendell, also from the University of St. Andrews, and colleagues investigating shared feeding behaviors in humpback whales, and animal cultures.
