Justification of Red List Category
This species has a moderately small and fragmented range which is declining owing to habitat loss and degradation. Consequently it qualifies as Near Threatened.
The global population size has not been quantified, but this species is described as uncommon, or rare and local.
A slow to moderate decline is suspected, based on on-going habitat loss/degradation and loss of historically occupied sites.
Ochthoeca piurae occurs locally in the Andes of Piura south to Ancash, north-west Peru. It has been recorded in Palambla (in Piura), Porculla (Lambayeque), Samne and Sincicap (La Libertad), and Colcabamba, Wiñapatun, Noqno and San Damian (Ancash) (Fjeldså and Krabbe 1990, Fitzpatrick et al. 2004, I. Franke in litt. 2004, Valqui 2004). However, it is apparently absent from other areas in north-west Peru where appropriate habitat exists, and it has been suggested that the present distribution of the species is limited to relatively good populations in the department of Ancash and southern La Libertad and small populations around Porculla Pass and Amotape, and that the northern populations have nearly disappeared (I. Franke in litt. 2004).
Its ecological requirements are poorly known (Best and Kessler 1995). It occurs at the edge of semihumid forest, in montane scrub (Schulenberg et al. 2007), on shrubby arid hillsides, and in riparian thickets (Ridgely and Tudor 1994, Fitzpatrick et al. 2004), at 1,400-2,850 m (Schulenberg et al. 2007), occasionally to 3,300 m (Parker et al. 1996). Its diet is unknown, but is presumed to consist of insects (Fitzpatrick et al. 2004).
It is not as threatened as many forest-dependent species in the region (Stattersfield et al. 1998), but ongoing habitat clearance and degradation of montane scrub and riparian thickets, in conjunction with overgrazing, are presumably causing population declines.
