i think that there is a seasonal difference in the timing of robins'
migration flights because the seasons are different every year. and if the
robins go to a warmer place on the same exact day every year, they would end
up going to a place that is going to be cold where there is no food or
anything.Some how they know when it is going to be cold, and when it is going
to be warm.
