Somali Grosbeak

Rhynchostruthus louisae

Handsome chunky gray-brown finch with a massive dark bill, dark-brown cap, and blackish face mask extending to the throat. Female has a paler forehead and crown. Juvenile is streaky with a more diffuse mask. Ecology is poorly known but presumed to be similar to that of Arabian Grosbeak, with pairs and small groups frequenting thorn-scrub and riverine vegetation up to 1400m in the northern Somali mountains, where it is a scarce endemic. Vocalizations largely unknown, but presumed to be similar to those of Arabian Grosbeak. In addition to range, other “golden-winged” grosbeaks differ from Somali in having pale ear-patches.

识别特征

The males are grey-brown overall with a black bill that is smaller than in the other golden-winged grosbeaks. It has a dark face mask and large, bright yellow patches on the wings and tail. The females are similar to the males though somewhat duller, and the juveniles are rather streaky and the face mask is indistinct.

行为

The Somali golden-winged grosbeak is typically found between 1,060 and 2,800 metres ASL in forested wadis and areas of scrub, namely in relict East African Juniper (Juniperus procera) forests. The juniper fruit appear to form the bulk of its diet.<p>This bird is the least-known of the golden-winged grosbeaks. Even before the start of the Somali Civil War in the late 1980s, little ornithological fieldwork was being done in this country. While no estimate of population size exists, it seems fairly certain that since the 1930s the birds have declined in numbers, perhaps due to habitat loss and more recently, declining rainfall in the region. Therefore, when it was first evaluated as a distinct species for the 2008 IUCN Red List, it was categorized as a Near Threatened species.

Scrub Honeyeater

Scrub Honeyeater

Meliphaga albonotata

A medium-sized honeyeater of foothill and mid-mountain scrub. Uniform olive green with a white ear spot and indistinct streak in the base of the bill. Some geographical overlap with the similar Forest Honeyeater, the only other similar species with a white ear spot, but Scrub Honeyeater has more green in the wing and is usually in scrub rather than forest interior. Call, a “chup!” similar to other similar species or a rapid series of whistles.

Variable Hawk

Variable Hawk

Geranoaetus polyosoma

Common raptor in open spaces in the high Andes and southern South America. Large, relatively broad-winged, and short-tailed raptor. As the name suggests, plumage is quite variable. Adults range from clean white to dark gray and rufous below with a gray or rufous back. Always look for the white tail with a black band near the tip. Juveniles are more confusing, usually dark brown above and buffy below with a variable amount of dark streaking below. Juveniles can also be all dark brown (but this morph is rare). Compare with Black-chested Buzzard-Eagle, which is larger and broader-winged, with young birds usually darker than most Variable Hawks. Occurs from sea level up to over 4,500 m in the Andes, typically in open agricultural land, desert, or paramo, but also ranging over wooded areas.

Rusty-tailed Flycatcher

Rusty-tailed Flycatcher

Ficedula ruficauda

Medium-sized brown flycatcher with an orangish tail. Note upright posture and broad-based pale bill. Forages quietly and usually singly in the lower levels of forest edge, both through gleaning and flycatching. Breeds in open forests in hilly and montane areas at 1500-3000 meters of elevation; in the winter, favors forest edge and clearings. Song is a descending whistle followed by a brief sputter of shorter notes: “Weee-pewchewchi!”
