Why is polar region not a suitable habitat for tiny humming birds ?
Asked by gudia13121995 | 23rd Nov, 2014, 12:03: PM
The humming birds have large surface area relative to their volume so and tend to lose body heat very fast in colder regions. They also require more energy to generate body heat. Hence, they are rarely seen in polar regions.
