The 'runner's in the details

Click on this close up of a Greater Roadrunner for a look at the beautiful colors on the head. From the link (allaboutbirds.org):


A bird born to run, the Greater Roadrunner can outrace a human, kill a rattlesnake, and thrive in the harsh landscapes of the Desert Southwest. Roadrunners reach two feet from sturdy bill to white tail tip, with a bushy blue-black crest and mottled plumage that blends well with dusty shrubs. As they run, they hold their lean frames nearly parallel to the ground and rudder with their long tails.
[...]
Roadrunners have evolved a range of adaptations to deal with the extremes of desert living. Like seabirds, they secrete a solution of highly concentrated salt through a gland just in front of each eye, which uses less water than excreting it via their kidneys and urinary tract. Moisture-rich prey including mammals and reptiles supply them otherwise-scarce water in their diet. Both chicks and adults flutter the unfeathered area beneath the chin (gular fluttering) to dissipate heat.

Now you know!
