Halmahera Paradise-crow
Lycocorax pyrrhopterus
A large, blackish, crow-like bird-of-paradise, endemic to Halmahera and adjacent smaller islands (not Obi and Bisa). Body is entirely blackish with paler, browner wings. Also often shows a thin line behind the eye. Shape is distinctive, with thin neck and small head with distinctive brow ridges. Juveniles are browner overall. Singles and pairs occupy canopy in forest, forest edge, and plantations in lowlands and hills. Brown cast to wings and head shape differentiate it from crows. In flight shows broad wings and an awkward, clumsy, hurried flight, unlike the slow flapping of crows. Calls include a hoarse “wek” and a high-pitched, nasal “we-huk.”
Identification
The Halmahera paradise-crow is a medium-sized bird-of-paradise, reaching a body length of up to 42 cm, with a dark, soft and silky plumage that may appear all black, but is in fact a very dark brown. Both sexes are similar; the female is slightly smaller than the male. The nominate subspecies has the least or no white patch on the inner flight feathers.<p>The head is slightly glossy black-brown and the upper parts are lighter than the head. The upper plumage shines slightly, with a blue-gray shimmer that is most pronounced on the coat, with cinnamon-brown wings. It has a black bill, crimson eyes, and a call reminiscent of a dog's bark.<p>It was originally thought to be a crow (Corvidae), and was then reassigned to the birds of paradise, where it is the earliest known offshoot from the paradisaeid family tree, dating back approximately 17 million years in the Miocene period. Lycocorax is derived from the Greek lycos, a wolf, and korax, a raven. Pyrrhopterus means red-winged, from the Greek pyrrhos, a flame or the colour red, and pteros, wing.

Range and habitat
The Halmahera paradise-crow is occurs on the Northern Maluku islands of Halmahera, Bacan (Batjan), Kasiruta, Morotai and Rau. There are two subspecies, which occur in the following regions of Maluku.<p>Lycocorax pyrrhopterus pyrrhopterus — Halmahera, Kasiruta, and Bacan<p>Lycocorax pyrrhopterus morotensis — Morotai, and Rau<p>Previously, the Obi paradise-crow (Lycocorax obiensis) was treated as a subspecies of the Halmahera paradise-crow. However, due to its distinctiveness and potential for separation, it was split from L. pyrrhopterus in 2016, with the International Ornithological Congress also following through in 2021.

Behavior
The nominate form is a forest dweller, also found in gardens and forest edges. It prefers the taller trees of the forest interior and is not typically seen in the more open agricultural areas. Seldom found in swamp forest or mangroves, it sometimes occurs in Coconut plantations and orchards, and frequents the mid-level to lhe canopy of the vegetation. The diet of the paradise-crow is composed mainly by fruit, with some supplement from arthropods, both of which are foraged mainly from dense canopy and middle foliage.<p>The breeding season is approximately December to June, with eggs laid over the same period. As the sexes are similar, it is likely that the species is monogamous, but breeding behaviour is almost unknown. Halmahera nests are described as a large basin-shaped structure made of roots and moss and lined with soft chips of wood, and the clutch appears to consist of just a single egg.

Common Snipe
Gallinago gallinago
Squat, cryptically-plumaged shorebird with a very long bill. Inhabits a wide range of wetland habitats, from damp meadows to saltmarshes. Mostly inconspicuous, feeding in muddy ground by probing with its bill, usually near reeds or other grassy cover. Often not seen until flushed, when it usually rises from fairly close range with a rough rasping call. Breeding birds are more conspicuous, perching on fence posts. In display flight, birds stoop from high overhead and produce a pulsating, bleating sound from air passing through their fanned tail. In Asia, beware of extremely similar Pin-tailed, Swinhoe's, and Latham's Snipes, all of which lack the white trailing edge of Common and have a slower, less erratic flight.
Great Grebe
Podiceps major
Huge grebe with a long dagger-like bill, a dark gray head, and long, thin rufous neck. The face is paler gray in the nonbreeding season. Inhabits large open areas of water including large rivers and coastal lagoons. Outside of the breeding season may be found on estuaries and along the coast.
Golden Parakeet
Guaruba guarouba
Remarkable Brazilian parakeet whose golden-yellow plumage and green flight feathers match the national flag. Found in humid forest, old second growth, and seasonally flooded forests. May also be encountered flying in noisy groups over neighboring agricultural areas.
