Note: These Challenge Questions coincide with the Spring 2005 Reports Challenge Question #3 From: by way of Jane Duden Journey North <susamel@brounstein.com> Date: Mon Mar 07 2005 - 09:20:00 EST It makes sense for the robins to migrate with the 36-degree isotherm because robins like it cool. When the temperatures go above 36 degrees in the spring, the robins body temperature cannot adapt to this warm weather. Therefore, they move.
