Animal Consciousness: Corvids Demonstrate a Sense of Fairness

a pair of biologists at the University of Vienna trained six carrion crows and four ravens to exchange pebble tokens for food. The researchers then created same-species pairs for a series of experiments. When the birds saw their partners getting food for free, without having to exchange tokens, they tended to exchange tokens less often. Sometimes the birds that got the short shrift even gave away tokens, but refused to take their reward. Other research has suggested that a sense of equity evolved several times in unrelated animals, the University of Vienna researchers write. Knowing what’s fair is linked to cooperative behavior in species, they say, and that makes sense with crows and ravens, which form alliances and share food and information.

“Jarvis’s holographic keyboard designs were replete with exotic symbols and undefined characters. Meinerding adapted keyboard characters from sources as diverse as mythology and electrical engineering figures…The net result of such subtleties reinforces that the mind of Tony Stark is so advanced that he and Jarvis are essentially speaking to each other in a language uniquely their own.” - The Art of Iron Man

There are more than three dozen species in the family Paradisaeidae, more commonly known as the birds of paradise. Most are distinguished by striking colors and bright plumage of yellow, blue, scarlet, and green. These colors distinguish them as some of the world’s most dramatic and attractive birds. Males often sport vibrant feathered ruffs or amazingly elongated feathers, which are known as wires or streamers. Some species have enormous head plumes or other distinctive ornaments, such as breast shields or head fans.

Males put their bright colors and unusual ornaments to good use when they display for females. Their elaborate dances, poses, and other rituals accentuate their appearance and put on a phenomenal show for both female birds and any humans lucky enough to be in the vicinity. Such displays can last for hours, and in many species they consume a significant part of the male’s time.
