Mean ± SE retinal carotenoid levels of house finches in experiments 1 (a) and 2 (b). In experiment 2 (b) “supp.” birds received a zeaxanthin supplement in their drinking water. The major retinal carotenoid types measured in house finches were astaxanthin (Asta), galloxanthins (Gal), lutien (Lut), zeaxanthin (Zea), an unidentified carotenoid (Unk), and ε-carotene (ε-car)
