White-rumped Tanager

Cypsnagra hirundinacea

An unmistakable medium-sized tanager with a black back, a white rump, and two white wingbars. Note the rusty throat and sides. Inhabits grasslands with scattered trees. The noisy song, which is usually delivered in a duet consists of melodic whistles; “whew chid-di-di-wee-wee-tyóó chid-d-o-wóó chi-d-dee-tyóó.”

The taxonomy is a little complicated. The white-rumped tanager was formally described in 1823 by German naturalist Hinrich Lichtenstein under the binomial name Tanagra ruficollis. Unfortunately, this combination had been used in 1789 by German naturalist Johann Friedrich Gmelin for what is now a subspecies of the Greater Antillean bullfinch with the trinomial Melopyrrha violacea ruficollis. In 1831 the French naturalist René Lesson described the white-rumped tanager and introduced the name Cypsnagra (as a subgenus) and the binomial name Tanagra hirundinacea. The type location is Franca in the state of São Paulo in Brazil. The genus name Cypsnagra is a mixture of the Ancient Greek kupselos meaning "swallow" and the genus name Tanagra. The specific epithet is from Modern Latin hirundinaceus meaning "swallow-like".<p>Two subspecies are recognised:

South Pare White-eye

South Pare White-eye

Zosterops winifredae

A small, sharp-billed warbler-like bird with a yellow throat and vent, otherwise gray underparts, and broad white spectacles around the eyes. Found in heath vegetation on the edges of montane forest at the highest elevations of the South Pare Mountains, usually in hyperactive flocks. Separated from similar broad-ringed white-eyes by range. Also somewhat similar to African Yellow and Pale White-eyes, but found at higher elevations, and grayer below. Most common call is a high-pitched, descending rattle. Song is a subdued, chatty sequence of “chew” notes. 

Spotted Harrier

Spotted Harrier

Circus assimilis

Long-legged medium-sized raptor with long narrow wings. Adult has chestnut underparts with striking white spots; immature streaked below. Flies low at slow speeds over open habitats. Often perches on fence-posts. Occurs in drier habitats than Swamp Harrier.

Violet Crow

Violet Crow

Corvus violaceus

An entirely blackish short-tailed crow. Has a subtle purplish sheen that is visible in only certain lighting conditions. Juveniles lack purple gloss. Inhabits forest, edge, and plantations in the lowlands and foothills. Singles, pairs, or small groups can be found in the canopy. Recently described from Seram, and perhaps also occurs on Ambon and Buru. Unmistakable, being the only crow on these islands. Gives an odd call for a crow: a nasal, trumpeting “errr.” Gives more crow-like sounds too, but higher-pitched than many sounds of the family, including a high-pitched, guttural “kreh-kreh…”.
