Birds are found in a broad range of habitats. This is partly because they can generate their own body heat (homeothermic). If they can insulate their bodies from variations in the surrounding temperature, they can even survive in polar regions where reptiles and amphibians do not occur. As a result birds also can eat a variety of different types of food.
The beaks of birds reflect the food type they eat. The feet of birds can also aid identifying the type of environment the birds frequent. Compare the beaks and feet in the birds on the table and determine which birds go with which lifestyle listed below.
A. Duck Sand Piper Pelican
