These issues of the National Geographic contain spectacular photos of pollinating animals, both birds and insects, at work. Since there is almost no audiovisual material on the subject, it would be desirable to cut out these pictures with their captions and display them in the classroom during the unit
I found these issues in various thrift shops in New Haven.
