The program did not emphasize migration for nesting purposes, but 
more for food resources during the winter, although egg-laying was 
briefly touched upon.  I meant the image literally but also generally, 
for who on this list could watch a program such as this and not see 
living dinosaurs?

The "when to migrate" signal for the different birds was also interesting.
