Black-naped Tern
Black-naped Tern, 30–32 cm, breeds on tropical Indo-Pacific coral islands from the Maldives to Polynesia. White overall with a narrow black nape band connecting the black lores — a delicate, elegant pattern. Piscivore; surface-dips and shallow dives in clear tropical waters over reefs.
