Cristina Robinson, et al: Complex birdsongs help biologists piece together the evolution of lifelong learning
Our human ability to learn language slows down as we get older, but scientists are not sure how or why this happens. An unexpected way to understand this learning process might come from listening to birds sing.
John Fitzpatrick, Director of the Cornell Lab of Ornithology, takes us on a bird-tour of the Mississippi River Delta. The Louisiana wetlands that they call home are fast disappearing.
There are about 9,993 living species of birds known by scientists. A collaboration between scientists at Yale and the Zoological Society of London have analyzed all of them and ranked 100 bird species based on conservation status and how unusual they are compared to other birds.
