Challenge Question #8
Date: Mon Apr 25 2005 - 09:34:37 EDT
1. It makes sense for males to arrive before females because the female comes after the male
establishes his territory and picks the site for the nest. When the female appears, the male
makes a courtship gesture by flying back and forth in a perfect arc.
2. If the migration is delayed, it means the weather is bad. Therefore, the male will not have
had time to establlish his territory. The males may be late, but the females aren't. The female
will arrive before the male because she left on time without the male having a head start.
