The White-fronted/White-browed Amazon, also called the Spectacled Amazon from Central America and Mexico, is the smallest Amazon at 24-25 cm.
Males have red "shoulders" (leading edge of wing); they are one of three Amazons (including Yucatan and Red-spectacled) where males and females can be identified by plumage.
Some individuals, especially females (above right) and juveniles, have incomplete red eye-rings ("spectacles") and incomplete white brows.
The Yucatan or Yellow-lored Amazon, native to Mexico, Belize and Honduras, is one of the smallest Amazons at some 26 cm length.
Unusually for Amazons, the male, with a white crown and red eye/cheek, has different facial plumage from the female with blue crown and no red eye-ring.
The Red-spectacled Amazon is native to Argentina, Paraguay and Brazil. Males have more red plumage, especially on the "shoulder".
