Book Club Birds, Amazon Burning. August 23, 2019, Part 1

“Bird-brain” has long been an insult meant to imply slow-wittedness or stupidity. But in reading Jennifer Ackerman’s The Genius of Birds, SciFri Book Club readers have been learning that birds often have wits well beyond ours—take the mockingbird’s capacity to memorize the songs of other birds, or the precise annual migrations of hummingbirds and Arctic terns. Or the New Caledonian crow, which make tools and solve puzzles that might mystify human children. UCLA pigeon researcher Aaron Blaisdell and University of Wisconsin neuroscientist Lauren Riters join Ira and producer Christie Taylor to talk about the brightest minds of the bird world, and the burning questions remaining about avian brains.

The Brazilian rainforest is experiencing a record number of fires this year—an 83% increase over 2018. Since last week, smoke from an estimated 9,500 fires has blocked out the sun for thousands of miles, covering cities like São Paulo in a dark cloud. Environmental agencies and researchers suspect the fires are human caused, cattle ranchers and loggers who are looking to clear the land for their own use. Ryan Mandelbaum, science writer for Gizmodo, gives us a rundown of the unprecedented destruction currently underway, and other science headlines, in this week's News Roundup.

Plus: In North Carolina, electric vehicle charging stations will start operating more like gas pumps. David Boraks, from WFAE 90.7 in Charlotte, tells Ira more in "The State Of Science."
