James River eagle recovery enters final chapter

http://www.ccbbirds.org/2017/07/11/james-river-eagle-recovery-enters-final-chapter/

Quote: "We believe that the disruption of breeders by floaters represents the negative behavioral feedback that is pulling down productivity and will ultimately bring the population into equilibrium with available breeding space."

What 'Thrones' fans already know: Ravens can see ahead

https://phys.org/news/2017-07-bird-brain-ravens.html

A raven's memories are for the future

Ravens parallel great apes in flexible planning for tool-use and bartering

http://science.sciencemag.org/content/357/6347/202.full


Tool-using raven. In a separate experiment, a raven involved in the Kabadayi and Osvath study uses a stick to poke for food in a tube (first photo). She succeeds in pushing the stick into the hole (second photo), but handling the stick is tricky for her. She then invents a new way of solving the problem: She fills the tube with bark pieces (third photo) and thereafter pecks at the bark until the food falls out.
