A rare phenomenon in the bird world, these Common Ravens are joined together from the side of their lower abdomens, sharing a common lower body , one pair of legs, a wide set of tail feathers and the same wings. Note there is something in the beak of the lower head, the other has reflected light on the tip. .Just kidding, this photo was uploaded on April 1st and the commentary above was an April Fools joke! These in-close, synchronized formations are not all that uncommon during Raven pair acrobatics, especially when they are soaring. I wonder if there might be some aerodynamic advantage in this sort of thing. Perhaps better use of available lift from the wind or something? Not sure what to make of it. Raven fact of the day: Even after a pair have bonded, it can take a year or more to build up sufficient mutual trust and a strong enough bond that they will share food. Once this happens, one bird can beg for food and the other will usually share, an adaptive advantage when food is scarce. Ravens have a special purpose display and vocalizations for begging.
