Parrots:

Recent research shows these birds don't just repeat what we say -- they comprehend it! "Parrots have the intelligence level of a four year old child," says Irene Pepperberg, Ph.D. who has studied birds for the past 20 years. In fact, they can understand up to 40 words, grasp concepts like "same" and "different," and use deductive reasoning.

1. I remember being taught that

the adaptation of flight is so competitively advantageous that Aves could have evolved to become the dominant vertebrate class on the planet, given relative cranial capacity; except that, the concomitant development of the avian optic nerve limited expansion of the avian brain. One professor's speculation, at any rate.

No wonder we (I) enjoy them so much; like hanging with kids at interesting learning stage!
