Population justification: Simple extrapolation of density figures in the Aberdares indicates a population there of c.50,000 birds (L. Bennun in litt. 1999, 2000, W. Gatarabirwa in litt. 1999, 2000), thus the population is placed in the range bracket for 50,000-999,999 individuals.

Trend justification: The rapid loss of grassland at Mau Narok and Molo, which now covers less than a third of the extent estimated in the late 1990s (P. Adhiambo in litt. 2007), suggests that the population is experiencing a rapid population decline.
