Fulger og intelligens

Bird intelligence The level of intelligence in birds, as a scientific inquiry, has not been as thoroughly researched as similar questions regarding primates and other mammals. See also: Plants & Animals Birds Zoology Nature Wild Animals Animals Behavioral Science However, there is a general belief that they are more intelligent, as a class, than the reptiles, and that many species are just as intelligent as mammals of comparable size. Because birds lack forelimbs with which to modify their surroundings, it is often difficult to test for intelligence as we would define it for mammals. Traditionally, biological science has maintained that most actions performed by birds that may indicate intelligence are merely ingrained instinctual behaviours and that birds are unable to learn. While parrots have the distinction of being able to mimic human speech, studies with the African Grey Parrot have shown that some are able to associate words with their meanings and form simple sentences. Along with parrots, the crows, ravens, and jays (family Corvidae) are perhaps the most intelligent of birds.  (Science Daily)

Mennesker er faktisk nærmere i slekt med hamstere enn fugler. Likevel viser det seg at flere fuglearter kan klarer oppgaver som krever tenkning og planlegging bedre enn mange pattedyr. Årsaken til at sjimpansen er blitt regnet som den mest intelligente dyrearten etter mennesker, er kanskje bare fordi det er den som ligner mest på oss mennesker?

Flyndre tatt med bunnmeite

Aner noen hva slags fisk dette er? Jeg kaller det "småflyndre", men jeg er altså ikke noen marinbiolog.
