Hume's Boobook

Smaller than all the gulls, with thinner and more pointed bill. Distinguished from other terns by pale whitish wings and orange-based bill in summer, and isolated black ear patch in winter. Forages by circling and hovering over bays, ponds, and lakes, then dropping to snatch fish. Often rests on sandbars, piers, and other structures with other gull and tern species. Snappy, quick wingbeats and acrobatic in flight.

The largest pigeon in the region, with dark purplish plumage except for metallic green around the neck. Generally uncommon endemic of islands off Japan, and to a lesser extent South Korea and Taiwan. Occurs in mature broadleaf forests, where it forages on the ground or in canopy. Also favors pines, especially in the Ryukyu Islands. Rustles about loudly when feeding. Deep call and slow moaning song may recall the everyday Rock Pigeon.

A large, alert-looking, white-bellied, brown lapwing with a distinct white “halo” around the dark crown. The immature is duller, but it retains the distinctive crown pattern. Small groups occupy open dry country, preferring cropped and recently burnt grasslands, where they forage for termites, ants, and other invertebrates. Commonly resident, but it also disperses when conditions become unfavorable. It gives a series of noisy, scratchy “kirre” calls that are distinctive.
