COOL BIRD FACTS

Here's some cool facts about birds I gathered while reading a manual of Ornithology:

  • A bird's body temperature ranges from 104-degrees to 111.2 -degrees

  • Birds range in size from only 2 grams (hummingbird) to 100,000 grams (ostrich).

  • Birds' brains and primate brains exhibit functional lateralization, with left hemispheric dominance associated with learning and innovation in vocal repertoires.

  • The highly developed color vision of birds reaches into the near-ultraviolet range of the spectrum.

  • The broad hearing range of birds encompasses infrasounds--sounds below the range of humans.
