Demography and Populations

Very little known. No estimates have been made of overall population size, although population appears to be stable. Recently rediscovered in south Eritrea (Adi Keih area) by JA with 4 records over 2 years (3).

Measures of Breeding Activity

No information.

Life Span and Survivorship

The only known evidence on longevity is Ash's record (25) of a bird found dying at Awasa, Sidamo, 8 years, 1 month after it was ringed in Addis Ababa.

Disease and Body Parasites

No information.

Causes of Mortality

No information.

Population Spatial Metrics

No information.

Population Status

Distribution across Afrotropical highland forest appears to be stable, when historical records are compared with recent records from eBird and field surveys (e.g., 21, 19, 20). Its rediscovery in Eritrea by JA (3) in 2008 after 50 years without records (since Smith, 28) is notable, and the absence of records in the interim may reflect a reduction in population density there, or simply a lack of records due to conflict. However, Blanford, writing in 1870 (4, p. 356) also indicates a low population density from this northern part of its range: "Occasionally seen about Senafe and Adigrat, but not very common." Friedmann (8) also suggests the species was uncommon in 1937, including other sources (e.g., "Zedlitz", no reference given). More recently, Spottiswoode et al. (1, p. 157) note "it is not necessarily easy to find" in Ethiopia, and Anderson and Berhane (3) report it as "rare" in Eritrea, observed only in the Adi Keih area 4 times over 2 years. This is consistent with BirdLife International's assessment in 2016 as "Least Concern" (29).
