Have you ever experienced seagulls seemingly begging for food from you? It is not your imagination. A new study finds that seagulls really do prefer foods that have been handled by humans. The study conducted Madeleine Goumas (University of Exeter, UK) examined whether seagulls picked up on cues from humans or were simply looking for food. While standing about 8 meters away from herring gulls, the team placed two plastic-wrapped […]
A new study published in the Proceedings of the National Academy of Sciences shows that ravens appear to share negative emotions. The researchers started with offering birds two boxes placed on the left and right sides of the animals. While one box was empty, the other contained a piece of cheese (yum!). They then placed a box in a new location and examined how the birds responded. If a bird acted […]
A new study published by researchers at the University of Rennes in France shows that epileptic seizures produce a distinct body odor profile that can be detected by dogs, opening up the possibility of training the animals to predict (and warn their owners about) these types of seizures. Sources: Video: YouTube Catala A, Grandgeorge M, Schaff J-L, Cousillas H, Hausberger M, Cattet J. Dogs demonstrate the existence of an epileptic […]
Video captured by Rebecca Otey (via YouTube) at the Butterfly Pavilion in Colorado seems to suggest that perhaps octopuses dream in their sleep: Although it is not clear whether octopuses really are dreaming when they change colors in their sleep, researchers at the World Science Festival in 2011 discussed work studying changes in brain activity of animals during sleep compared to wakefulness to gauge whether they may be dreaming:
Yes, you read that right. Ornithologists in Australia have received enough witness accounts of birds starting new fires by picking up burning twigs to believe the birds may actually be starting fires deliberately. They think these so-called ‘firehawks’ start fires to flush out prey. Yikes!
