Cryptic diversity in the Amazonian Red-shouldered Tanager (Tachyphonus phoenicius) Swainson 1838 with a neotype designation and revalidation of Tachyphonus saucius Strickland 1844 - Journal of Ornitho... The Amazon is home to the greatest bird diversity in the world, but its avian diversity is still underestimated, partially due to cryptic diversity. An accurate assessment of cryptic species is necess...
