This is a gorgeous book about some of the world's most gorgeous birds: sunbirds and their allies. They are often compared to jewels because of their small size and bright or iridescent colors. As striking as their appearances are their behaviors – flowerpeckers skin mistletoe berries as neatly as waiters in Michelin 3-star restaurants peel fruit. Read this updated volume, enjoy its photos and maps and text, and then go see these jewels for yourself!

This second edition of Sunbirds of the World is an indispensable and definitive guide ... Its strength lies in its comprehensive integration of updated taxonomic frameworks and the critical analysis of emerging molecular data alongside traditional morphological and behavioural insights. The detailed anatomical, physiological, and ecological information, including novel discussions on tongue mechanics, plumage development, and parasite dynamics, provides a rich scientific foundation
