Question of the Week Answer
If you answered c, you are correct!
 Animals living in hot environments tend to be smaller than relatives found in colder environments—a general pattern known as “Bergmann’s Rule.” Gilded Flickers, which inhabit very hot deserts and are smaller (by one to three inches in length) than Northern Flickers, are an example of this rule. Add a flicker of gold or a Gilded Flicker to your day - The Gilded Flicker can be found on your public lands in the El Centro, Needles and Palm Springs-South Coast field offices along desert riparian, desert wash and Joshua tree habitats of the Colorado River Valley. Fun Northern Flicker fact: they have the longest tongue of any bird in North America. For "Respect Wildlife" tips, visit: http://ow.ly/juWM50LY1jC
