I think that Robins migrate with a 36 degrees isotherm because it will
take them to their destination to find the warmest possible place to
go for the winter. They follow the isotherm because that will give
them the direction for where they can head. They migrate with the
isotherm because it is getting warmer as they go up north.Tthat's how
they know when to migrate. This will also tell them where there food
is.
