New evidence of tool use discovered in parrots. Very smart! Be sure to watch the video at the end of the article.

T40, thanks for this story!  Very good stuff.  I enjoyed the video, too - but it took me 4 "looks" to find the link to it... don't ask me why.   ::)

Kestrel inspires unpowered, autonomous glider to climb higher

http://www.sciencedaily.com/releases/2015/12/151218085931.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29

Thanks, T40!  I loved reading this!  It has wonderful info on special flight abilities of kestrels and why this project is trying to learn more about how to employ some of the kestrel's same special flight abilities.  Gliders are so cool, but they still can't do what birds can.

I don't pretend to understand this, but it's fascinating.

Nature's unique way of controlling color explains why birds never go gray
