We spent the morning of Monday, January 16, 2012, birding along Yarapa Creek, a tributary of the Amazon (South Bank). I photographed a Green-backed (White-tailed) Trogon, Trogon viridis, that was perched in the branches of an Acacia tree. The belly is an orangish-yellow color. Males have black cheeks and throat with the rest of the neck, head, and upper chest blackish with an iridescent purplish-blue hue. The back is an iridescent green that blends into a purplish-blue on the rump. The upper tail is a bronzy green narrowly tipped with black. The male's undertail is patterned broadly white on black. The eye ring is blue. (Remember: coloration may vary due to poor light.) Temperatures were in the upper 70's with hazy skies and high humidity.
