Identification
The Streaky Seedeater is a medium-sized finch, quite stocky and heavily streaked with a large head, short and conical beak and a long lightly-toothed tail. There is no sexual dimorphism. The upperparts are generally brown streaked with buff and the underparts buffish to whitish. The brown head is marked by long and wide buffish-white eyebrows reaching the back of the neck. The lores, parotids and sides of the throat are dark brown, the eye is underlined by a small buffy crescent, and a small variable-sized buffy moustache can be seen on the cheek. Looking in front, a clearly buffish-white tinged, or not, with yellow bib is visible. The base of the conical beak is brown and the mandibles are rosaceous. The iris is brown or chestnut-colored. The legs are dark brown. The cap and the neck are brown, more or less streaked with buff-white. The mantle, back and scapular feathers are brown-olive heavily streaked with blackish-brown and bordered with buff-white. The rump is pale-brown streaked with a darker hue and the rectrices are dark-brown fringed with green-olive. The flight feathers are blackish with the primaries finely bordered with yellow-green or green-olive, and the secondaries bordered by brown-olive becoming largely white. The coverts, chest and flanks are buff-white finely streaked with brown. The belly is whitish more or less streaked. Individuals of the subspecies C. s. graueri are slightly darker on the upperparts than the nominal subspecies C. s. striolata, with fine or indistinct green edgings on the flight feathers, and more heavily streaked on the underparts with a deeper or richer buff-brown. The juvenile is similar to the adult, but duller.The forehead and crown are lighter tans and the lower parts are generally less streaked.

Voice song and cries
The song of the Streaky Seedeater is varied. It can be a series of short, clear and descending whistles tway, tway, tsitsi-peeew, tsiway-tslo or a series of longer notes including trills, short notes and dry chattering. All of these phrases are well separated and can last several seconds. The call is monotonous sweee or chweee-chip-chip-chip-chip or chididi see-leep and fades at the end. Finally he emits other call notes including sooee, seeeeeit or suwee-ip high-pitched.
Habitat
The Streaky Seedeater is accustomed to open landscapes of low and middle mountains. It can also be found on the edges of woods and in clearings, in the middle of secondary humid perennial leaf forests and arborescent heathers. Locally it is encountered in junipers, heaths and alpine meadows, bamboo patches and in the scrub of ferns. It is also not foreign to crops and gardens, including the outskirts of large cities such as Addis Ababa in Ethiopia and Nairobi in Kenya.
Behaviour character trait
The Streaky Seedeater is a resident species. A few short distance and random movements have been observed in Kenya.
Dietfeeding habits
The Streaky Seedeater is mainly granivorous. Apart from the small seeds it gathers on the ground or in vegetation, it can feed on berries, notably blackberries, insects, such as aphids, termites and small coleopterans.
Reproduction nesting
Streaky Seedeater reproduces generally throughout the year. In Kenya the period mainly extends from April to August and October to January, but exclusively from April to July when its presence is over 2000 metres.
Geographic range
The Streaky Seedeater can be found in the high plateaus of East Africa, ranging from Eritrea in the north, where it is abundantly local, to the Albertine Rift and the center of Tanzania. It is also present in the east of the Democratic Republic of the Congo, and in the west of Burundi and Uganda. Its altitudinal distribution then varies according to the country. It generally inhabits elevations between 1300 and 4300 m in Kenya and East Africa, between 1510 and 4100 m in Ethiopia, and between 1675 and 4250 m in the east of the Democratic Republic of the Congo. In Eritrea it can be found as low as 950 m. Two subspecies have been identified. C. s. striolata: in Eritrea, Ethiopia and southeast Sudan, southwards to western and central Kenya and north Tanzania. C. s. graueri: in the east of the Democratic Republic of the Congo, southwest Uganda, Rwanda, and Burundi.
