The color of male feathers results from 3 carotenoid pigments: ß-carotene, which produces yellow to orange color in feathers; isocryptoxanthin, which produces orange color in feathers; and echinenone, which produces red color in feathers. By doing controlled feeding experiments with captive house finches researchers found that all individual male finches in all populations all over the U.S. have same potential to be pink, orange, or yellow; the color variation based on the finch’s access to carotenoid pigments when they are molting (shedding old feathers and growing in new ones).#1282036

Well, I'll be doggoned! I never knew! Guess the males in my area have huge doses of carotenoid canthaxanthin added to their diet - a nice cheery (cherry?!) red, they are...BTW, a beautiful capture of both parents and a demanding young'un...love the bit of seed caught of Momma's beak. Good to see you back, T'weed! #8716077Bonnie C. Lackey June 25, 2010
