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.
Crows are frequently observed gathering around dead comrades. When researchers from the University of Washington investigated this behavior they found the crafty birds understand much about death and the threat of death by predators, not only reacting to their fallen brethren but also avoiding areas or things they deem dangerous.
In an act of choosing to lose the part but not the whole, a certain type of sea slug severs its back appendage to leave a predator holding the bag--or body part, as it were, according to a new study. Knowledge of how they do this could potentially lead to medical breakthroughs in helping wounds to heal.
Paleontologists suggest recently discoverd foot scrapes across several Colorado outcrops were made by large dinosaurs that competed in dance-offs to woo their mates.
Carpenter bees engage in dogfighting-like behaviors to defend their hives and prevent other bees from laying eggs in their carefully-constructed homes. Using a GoPro, researcher Dr. Brandon Jackson of Longwood University recently filmed the bee's rather unique aerial combat style.
Butterflyfish depend on food and shelter provided by coral reefs, but they steer clear of those that have come in contact with seaweed. Researchers suggest this may be a strong indicator of their awareness of reef health.
Genome sequencing, paired with a behavioral test, identified several genes linked to anxiety in chickens. Researchers believe the same genes may play a role in mouse and human behavior.
Vultures are not good at flapping their wings, but they manage to spend long periods of time in the air by soaring. Researchers found that these birds stay aloft by making use of small-scale turbulence that produces uplift without flapping their wings.
Humpback whales are spending some extra time up north in Alaska this season. Experts say the whales are slow to arrive at breeding grounds in Hawaii because of possible food competition or El Niño disruptions.
Although colonies of Florida carpenter ants have designated roles, researchers managed to turn foraging ants into scouts with the use of epigenetic drugs. This suggests social behavior is not necessarily based on an individual's genetics.
Although pitch perception was thought to be unique among humans, researchers recently discovered small monkeys known as marmosets use auditory cues to distinguish between low and high notes, just like we do.
Dogs can rapidly mimic each other's expressions, just like humans and some primates.
Regular, gentle pats and positive human interactions benefit growing calves. This could be advantageous for farmers, as cows produce more milk if they gain more weight at a young age.
Contact, rather than waterborne chemical signals, induces sex change in marine snails known as slipper limpets.
