Smart Parrot's Color-Matching Skills
Smart Parrot's Color-Matching Skills
Are birds smart? Do they have a keen sense of colors? This video perfectly answers both questions as this smart parrot demonstrates its color-matching skills.
Birds see more colors than humans – not only the familiar colors, but parts of the ultraviolet spectrum that are invisible to us as well. They also have better visual acuity to determine subtle differences between similar shades of color (possibly 50 shades of grey?) that humans cannot discern.
The cells in the eye responsible for color detection – cones – are positioned in the retina, and birds have four types of cones rather than the three humans have. The exact number of cones varies in each bird species but is typically higher than humans and other mammals.
Birds are highly intelligent, and that includes chicken and ducks too. Let's make more friends with birds, not food. Enjoy a compassionate meat-free meal at http://KindMeal.my.
