Population justification: The total population was thought to be very small, at no more than 2,500 birds (D. A. Turner in litt. 1999), but the recently revised population estimate of c.1,400 individuals for Zanzibar and over 1,000 in the Eastern Usambara, Tanzania (L. Borghesio in litt. 2010) suggests that the total population estimate should be recalculated. The subspecies T. f. zanzibaricus, endemic to Zanzibar (N. Baker in litt. 1999), was thought to number only 25-50 birds (D. A. Turner in litt. 1999), but following surveys in June-July 2001 the population has been estimated at c.1,400 individuals (Borghesio and Ndang'ang'a 2003). In Somalia, there are now probably fewer than 50 individuals left (D. A. Turner in litt. 1999), all in the lower Jubba valley, where up to 80% of the riverine forest has been cleared in less than 30 years (Madgwick 1986, Ash and Miskell 1998); thus there is little hope that the species will persist there. The population is therefore assumed to fall within the range 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Trend justification: Although a limited time series of data suggests a sub-population is Eastern Usambara is stable (Borghesio 2007, L. Borghesio in litt. 2010), the overall population is suspected to be in decline owing to the ongoing threats due to trapping and the clearance of coastal forests (del Hoyo et al. 1997). Tree cover loss within the range is currently estimated at 14% across three generations (15 years) (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Assuming that population declines are roughly equivalent to the rate of forest loss, the species may be declining at <20% over 15 years. This may have led to local extinctions such as at Watamu beach forest where habitat destruction and modification has led to this species not being seen there for 10 years (W. Knocker in litt. 2016).
