Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Purple grenadier

The purple grenadier (Uraeginthus ianthinogaster) is a common species of estrildid finch found in eastern Africa.

Description[edit]

The length averages 13.3 cm (5.25 in). All ages and sexes have a black tail, and adults have a red bill. The male has a cinnamon-colored head and neck with a blue patch surrounding the eye. The rump is purplish blue and the underparts are violet-blue with variable rufous patches. The female is smaller and mostly cinnamon brown with white barring on the underparts and silver-blue eyepatches. Juveniles are like females, but mostly unbarred tawny-brown with a reddish-brown bill.[2]

The song (in Kenya) is described as "a high, thin chit-cheet tsereea-ee-ee tsit-tsit, or cheerer cheet tsee-tsee sur-chit."[2]

The phylogeny has been obtained by Antonio Arnaiz-Villena et al.The phylogeny has been obtained by Antonio Arnaiz-Villena et al.[3]

Range and habitat[edit]

It is found in subtropical and tropical (lowland) dry shrubland in Ethiopia, Kenya, Somalia, Sudan, Tanzania and Uganda, an estimated global extent of occurrence of 1,500,000 km². The status of the species is evaluated as Least Concern.[4]

Origin[edit]

Origin and phylogeny has been obtained by Antonio Arnaiz-Villena et al.[5] Estrildinae may have originated in India and dispersed thereafter (towards Africa and Pacific Ocean habitats).
