The common chiffchaff (Phylloscopus collybita) is a small, migratory songbird found across Europe and parts of Asia. It is easily recognized by its olive-brown plumage, pale underparts, and distinctive, repetitive song that sounds like its name. This bird typically inhabits woodlands, gardens, and scrub areas, often near water sources. Chiffchaffs are insectivorous, primarily feeding on small insects and larvae during the breeding season. They are known for their adaptability and can thrive in various habitats. These birds migrate to warmer regions in winter, returning to their breeding grounds in spring, where they build nests in dense vegetation.
