The greater flameback (Chrysocolaptes guttacristatus), also known as the greater goldenback or large golden-backed woodpecker, gets its name from its golden or crimson backs – it has unmarked golden-yellow to dark brown back and wings. The adult male greater flameback has a red crown. It occurs widely in the northern Indian subcontinent, eastwards to southern China, the Malay Peninsula, Sumatra, western and central Java and northeast Borneo. Like other woodpeckers, the greater flameback uses its bill to dig out food from trees, and its zygodactyl feet and stiff tail to provide support against tree trunks. The long tongue can be darted forward to extract wood-boring arthropod prey; while mainly feeding on small invertebrates, greater flamebacks also drink nectar. They nest in tree holes, laying three or four white eggs.
