Cf. Blue-chinned Sapphire.<\/em><\/strong>\u00a0 Blue-tailed Emerald and Blue-chinned Sapphire overlap widely across northern South America, Amazonia, and Trinidad.\u00a0 The males can be extremely similar. \u00a0The emerald\u2019s bill is black, whereas the sapphire\u2019s varies from red to black, but usually shows at least a tinge of red on the underside.\u00a0 The emerald\u2019s tail is shallowly forked, whereas the sapphire usually has a square tail, although it can also appear notched.\u00a0 In good light, Blue-chinned Sapphire usually has a blue tinge on its chin, but this is not always detectable.\u00a0 Females of the two species are not similar.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
