Common Flameback

<em>Dinopium javanense</em> is a woodpecker belonging to the family Picidae within the order Piciformes. Commonly known as the common flameback, this species is characterized by its striking golden-yellow and black plumage with a vivid red crown, typical of flameback woodpeckers in the genus Dinopium. The species is classified as Least Concern on the IUCN Red List, indicating stable population trends across its range. Documented occurrences include Norway, though the species is primarily associated with South and Southeast Asia, inhabiting open woodland, forest edges, plantations, and gardens. <em>Dinopium javanense</em> typically forages on tree trunks and branches, using its strong bill to excavate insects from bark and decaying wood. The species is generally solitary outside the breeding season and is known for its loud, repetitive calls. Its diet consists primarily of insects, particularly ants and beetle larvae extracted from wood. Biological traits of this species remain poorly documented in the scientific literature.
