Chatham Island Gerygone Gerygone albofrontata

Small warbler endemic to the Chatham Islands of New Zealand. Note dull olive-brown upperparts and white to yellowish plumage below. Distinctive red eye. Males are larger and have a white forehead, eyebrows, chest, and belly. Females have more subtle coloring. Juveniles have brown eyes and a noticeable yellowish tinge to their underparts. Confined to southern forests and scrub. Forages for insects from tree trunks and leaves. Will come to the ground to forage, often in small family flocks. Listen for loud male song, a repeated 4-note phrase “chi-ch-ch-ch.” Some nests are parasitized by larger Shining Bronze-Cuckoo. Distinguishable from Silvereye by lack of distinctive white eye-ring.
