Crowned Woodnymph
Thalurania colombica
Male crowned woodnymphs are 9.5 to 11.5 cm (3.7 to 4.5 in) long and weigh 4 to 5.5 g (0.14 to 0.19 oz). Females are 8.5 to 9.2 cm (3.3 to 3.6 in) long and weigh 3.5 to 4.2 g (0.12 to 0.15 oz). Adult males of the nominate subspecies T. c. colombica have a violet forehead, crown, upper back, and belly. Their nape is dark bronzy green and lower back and rump dark bluish green. Their throat and chest are glittering green. Their deeply forked tail is blue-black. Adult females have bright green upperparts, pale gray throat and chest, and darker gray belly. Voice: What is thought to be the crowned woodnymph's song is "a monotonously repeated, single, plaintive squeaky chip, 'ksit...ksit...ksit..'". It also makes "short dry chips as dry trill or chatter".
