A recent study of carnivorous animals foiund that those with large brains (relative to their body size) are better at solving problems than smaller-bodied individuals. Of the 140 animals tested, bears were the most successful at retrieving their favorite snacks from inside a secured metal box.
In the face of a challenge, practice makes perfect for grey squirrels. Researchers from the University of Exeter found that squirrels were able to quickly learn which lever to either push or pull to release food from a closed box when they remained persistent.
In a 2014 survey of Morocco's island of Mogador, raptors called Eleonora's falcons were observed engaging in a what researchers called a new behaviour that ensures their offspring receive the freshest of meats: imprisoning smaller live birds before killing and feeding them to their young several days later.
Following the arrival of gentoo penguins along the West Antarctic Peninsula, native Adelie penguins have experienced population declines. However, researchers are unsure whether increased food competition among the two species or climate change is ultimately to blame.
While male bumblebees may be perceived as lazy, researchers recently confirmed the insects can forage just as successfully as their female counterparts.
After tagging over 500 bluefin tuna, researchers have determined that the internal temperature of Bluefin Tuna can be used to indentify where the fish feed and how impact ocean temperatures impact them. This discovery will help conservationists better protect the threatened species.
Mother butterflies pass down behaviors that help their offspring survive in less-favorable environments and tend to lay their eggs on the same plants that they and their relatives grew up on.
