I think that male robins return first so that they can establish
the best possible territories and attract the best females as their mates.
I have also learned from my research that it is usually the older male
robin who leads the way. The advantages of arriving early are the ability
to find the best territory, taking advantage of a plentiful food supply,
and being present when the first females arrive. The major disadvantages
would be that the ground would be too cold to get worms for food and
adverse weather such as snow and cold temperatures could endanger their
survival.
