Birds to Identify

Instructions: For those who want to play along, go over to our show notes where you will see photography of several birds.  Each bird photographed has been altered to simulate the perspective of someone who is colorblind.  Can you guess the bird?

Pause the podcast while you guess.  We’ll discuss each bird individually.
