Before watching the video below, make sure that you have first read and outlined section 19A. Then as you watch the lecture over section 19A, be sure to take lecture notes besides your reading/outline notes.

Once you've watched the lecture video, taken notes, and recorded your time on your video log sheet, then you are ready to answer the 19A Worksheet and do the matching worksheet on the structure of birds.
