Crows and ravens can be tricky to tell apart by sight, but their voices are much more distinctive. Watch this video for some expert tips on the sounds these two common birds make and what those sounds mean.
American Crows and Common Ravens have a repertoire of sounds beyond their signature “caw” and “kraa” calls. The crow often makes a rattle sound along with its territorial caw and also communicates through other click and bell-like notes. Ravens broadcast their presence through deep, throaty kraa calls. Narrator Kevin J. McGowan, an ornithologist at the Cornell Lab of Ornithology, uses harmless wing tags to study crows around the Cornell Lab. In this video, he compares the calls of American Crows with those made by Common Ravens.
The Intercept invites you to a special event in New York City hosted by senior correspondent Naomi Klein and headlined by trailblazing climate activist Greta Thunberg. Together with youth leaders Xiuhtezcatl Martinez, Xiye Bastida, and Vic Barrett, Greta and Naomi will help us visualize a just and sustainable future, confront our climate emergency, and discuss the emerging cross-generational, transnational movement that is our best hope for a sustainable planet. Both a celebration of youth activism and a reflection on how to break through the political and economic barriers preventing meaningful climate action, “The Right to a Future” will take place before the Global Climate Strike starting September 20 and the U.N. Climate Action Summit on September 23.
In this passionate call to action, 16-year-old climate activist Greta Thunberg explains why, in August 2018, she walked out of school and organized a strike to raise awareness of global warming, protesting outside the Swedish parliament and grabbing the world’s attention. “The climate crisis has already been solved. We already have all the facts and solutions,” Thunberg says. “All we have to do is to wake up and change.”
