Vegetarian Ideal


Nothing will benefit human health and increase the chances for survival of life on Earth as much as the evolution to a vegetarian diet.

Magpie Bird





The European Magpie is believed to be among the most intelligent of birds, and among the most intelligent of all animals. Magpies have been observed engaging in elaborate social rituals, possibly including the expression of grief.  Mirror self-recognition has been demonstrated in European magpies.  The magpie is thus one of a small number of species, and the only non-mammal, known to possess this capability.  The cognitive abilities of the European Magpie are taken as evidence that intelligence evolved independently in both corvids/crows and primates. This is indicated by feats such as tool use, their ability to hide and store food across seasons, episodic-like memory, and the ability to use one's own experience in predicting the behavior of conspecifics.   Various behaviours have been observed that indicate intelligence. It has been observed that they cut up their food in correctly sized proportions, depending on the size of their young. In captivity magpies have been observed counting up to get food, imitating human voices, and regularly using tools to clean their own cages. In the wild, they organise themselves into gangs, and use complex strategies when hunting other birds, and when confronted by predators.  Along with the Jackdaw, the European Magpie has been found to have a neostriatum approximately the same relative size as is found in chimpanzees and humans, and significantly larger than is found in the gibbon.  Like other corvids, such as Ravens and Crows, their total brain to body ratio is equal to that of great apes and cetaceans, and only slightly lower than in humans.
