Edgar Allan Poe’s The Raven gets read a lot in schools at this time of year. Why you should read Poe’s work is explained in one of the Halloween-themed TED-Ed lessons that I shared a few days ago. What’s not explained in those lessons is the difference between a raven and a crow. To answer that question, turn to a couple of resources from The Cornell Lab’s Bird Academy

Caw vs. Croak: Inside the Calls of Crows and Ravens is an interesting three minute explanation of the differences between the calls that crows and ravens make. The narrator of the video even explains what some of the different calls mean to the birds. 

American Crows and Common Ravens is a reference page that describes the physical differences between crows and ravens. At the bottom of the page there is a short and fun quiz to test your crow and raven identification skills. 
Applications for Education
If you’re fortunate to live in an area that has both crows and ravens, take your class on a little walk to see if they can spot the each and identify them by sight and or sound.
