I think you mean the third topic of Lesson one. It doesn't appear that there is a video for that topic.  There won't be a video for all topics. However I will double check with the content developers and get back to you. Thanks for asking. If you have further course related question please email us at birdacademy@cornell.edu as the discussion boards are more for students to interact with each other and won't always be monitored by staff regularly.
