The short-billed sylvietta ( Sylvietta philippae ) is a little researched songbird from the Macrosphenidae family . It is native to Somalia and Ethiopia . The kind epithet honors Philippa Gaffikin, the wife of the first descriptor John George Williams (1913-1997).

features

The Kurzschnabelsylvietta reaches a size of 8 cm and a weight of 9 to 10 g. The plumage is predominantly gray on the top and yellowish on the underside. The short beak is gray. The base of the lower mandible is pink. The skull and the top are ash gray. The narrow stripe above the eyes is whitish. The reins and face mask are dark gray. The upper wings and the stubby tail are gray-brown. The hand and arm wings have narrow, light hems. The chin and throat are white. The area from the chest to the under tail-coverts is light yellow. The chest and flanks are interspersed with gray-brown. The legs are brownish red. The sexes look the same. The youth dress has not yet been described.

Vocalizations

The singing consists of a repeating "ti-chirr-cheesis" with a higher middle note. The call consists of a “chirr” and a loud “chink”.

distribution and habitat

The Kurzschnabelsylvietta occurs in the northwest, in the middle and in the southwest of Somalia, in particular from Burao and Daba Dalol southwards to Iesomme and in the area around Wajit and Lugh. It has also been observed in the neighboring southeast of Ethiopia (in the Bhogal and Gheraro regions). The Philippa's Crombec inhabited dry acacia - and Commiphora -Buschland mainly m on bedrock or red sandy soil and on the plateau in the inland at altitudes of 300 to 600.

Way of life

The Kurschnabelsylvietta is a resident bird. Their diet consists of small beetles (Coleoptera) and other insects, including small caterpillars. Branches, leaves and flowers, especially those of acacias, are searched for. It is usually seen in small groups or socialized with other species. Little is known about the breeding behavior. The breeding season is between May and June.

status

The IUCN classifies this species in the category of “insufficient data” ( data deficient ). It is quite common, but is said to have a small and restricted range.

Systematics

The Kurschnabelsylvietta originally belonged to the warbler family (Sylviidae). After the African genera Sylvietta , Macrosphenus , Melocichla , Sphenoeacus , Achaetops and Cryptillas were split off from the Sylviidae family in 2008 and placed in the Macrosphenidae family established by Hans Edmund Wolters in 1983 , this transfer was taken over by the International Ornithological Congress in 2010 .
