• Heat Conservation Hypothesis

  • Bergmann's Rule: Populations of endotherms located in colder climates will have larger body sizes compared to those in warmer climates 

  • Allen's Rule: Populations of endotherms in warmer climates will have larger appendage sizes compared to those in colder climates 

• Purpose statement: Has change in temperature overtime had an effect on the morphology of birds in accordance to Bergmann's Rule and Allen's Rule in order to adapt to thermoregulatory needs.

  • Birds are particularly susceptible to changes in climate and environment, making them the perfect subject for this type of research
