Sula Hanging-Parrot

Loriculus sclateri

A tiny stub-tailed green parrot with a golden-bronze back, a narrow red throat, a bright red rump, and a small red shoulder patch. Juveniles are duller and more poorly marked. Singles or small groups occur within treetops of forest and nearby secondary growth areas in the lowlands. No other tiny green, short-tailed parrot occurs within its limited range in the Sula and Banggai islands. Very high-pitched calls include “zeet-weet-wit,” rising in pitch at the end. Sometimes birds only utter the first two notes or single “zeet” notes.

Taxonomy

The Sula hanging parrot has sometimes been treated as a subspecies of the Moluccan hanging parrot, but the two are increasingly treated as separate species based on their distinct differences in plumage and size (14 cm for the Sula hanging parrot versus 11 cm (4 in) for the Moluccan hanging parrot). When recognized as separate species, the Sula hanging parrot has often been treated as monotypic, but the subspecies L. s. ruber from the Banggai Islands has recently been re-validated, leaving the nominate for the Sula Islands. Both subspecies have an overall green plumage with red to the chin, rump and leading edge of the wing. In L. s. sclateri the mantle varies from all mustard-orange to red broadly edged by orange, while the mantle of L. s. ruber is red with very little orange edge. Furthermore, the red rump is brighter in L. s. ruber than in L. s. sclateri.

Behavior

The Sula hanging parrot is usually present in areas below 450 meters in old-growth forest, secondary forest, near agricultural land with scattered trees, plantations, and forest edges. It is usually found singly or in small groups. Pairs usually nest in tree and stump burrows, as they prefer narrow, long burrows with small holes. To carry back nesting materials to build a nest inside the burrow, this species tucks in materials such as small twigs under its wing and then carries it back to their nesting site. Breeding usually takes place from January to April while a second season happens from July to September. During breeding season the male performs an elaborate courtship display to attract a female. In the display, the male approaches the female with small steps and hops while making a warbling sound. He also extends his neck to show of his blue throat patch while raising his rump, displaying his tail feathers. The species also engages in courtship feeding. Females lay a clutch of 2 to 4 eggs. The female incubate the eggs for approximately 20 days while the male feeds her. Eggs are usually 15 – 18 mm long. Young birds fledge at around 32 days of age and are usually fully independent in 10–11 days.

Conservation

Like most other birds in the genus Loriculus, the Sulu hanging parrot is threatened by deforestation to make way for farms, mining operations, and logging. It is also threatened by the illegal pet wildlife trade.

Horned Lark

Horned Lark

Eremophila alpestris

Squat-looking bird with short legs and low-profile body. Adults are mostly sandy-brown with white belly, sometimes with blurry streaks on sides of breast. Look for bold head pattern, especially black mask and chest band. Throat color varies from yellow to white. Namesake horns on head are sometimes visible at close range. Juveniles can be confusing; they are messy-looking, grayish-brown with bold white spots and scallops on the upperparts. Note bill shape to help separate from sparrows or longspurs. Widespread in open habitats throughout the Northern Hemisphere. Typically seen in flocks, sometimes mixed in with other open-ground songbirds, running along the ground in open areas with little to no vegetation. Listen for lovely jumbled song, as well as variable high-pitched calls when flying over.

Eastern Yellow Wagtail

Eastern Yellow Wagtail

Motacilla tschutschensis

Attractive ground-dwelling bird. Slender and long-tailed, bright yellow below with paler throat and grayish-olive back; extremely variable. Tail is black with white outer feathers; often pumps tail up and down while walking on the ground. Young birds lack yellow color, but have distinctive head pattern. Often seen near water. Listen for high-pitched, piercing call note. Common breeder on Arctic tundra from Alaska to Russia; found in grassy and waterside habitats in Southeast Asian wintering grounds and in migration.

Viridian Metaltail

Viridian Metaltail

Metallura williami

Short-billed hummingbird found near tree line in the high Andes. Male is deep green with a dark and sometimes glittering throat patch; female is similar but lacks throat patch and is scaled buff or rufous below. Tail color varies geographically; it can be green or blue, and it can even show a bit of rufous on top, though never as much as the tail of Tyrian Metaltail. Feeds on small flowers in páramo and at the edge of elfin forest.
