||24 cm. Adults have uniform grey plumage, apart from a chestnut-brown crown and cinnamon undertail coverts. The bill is black, and there is an obvious complete yellow orbital ring. Juveniles show rufous fringes to the flight feathers and greater coverts. Similar spp. Most closely resembles Dusky Piha L. fuscocinereus, although the latter species is larger, has a grey crown, and lacks the yellow orbital ring. Voice A loud piercing sreeck.

This species has been uplisted to Critically Endangered. It has a very small population and remaining forest continues to be degraded and destroyed, therefore its population is likely to be declining.

|Range Description:||This species is confined to a small area of forest (c. 800 km2) on the northern slope of the Central Andes in Colombia (Cuervo et al. 2001), it had been known from just five locations (Renjifo et al. 2002) however it is now known from 16 sites (Cuervo et al. 2008, Cuervo 2014, Sharpe 2015, Snow & Sharpe 2015). The area lies between the Porce and Nechí river valleys, where it is presently known from four localities in the Municipality of Anorí (Cuervo et al. 2001). The species was considered to be locally common at the known localities in Anorí, especially between 1,600 and 1,750 m (Cuervo et al. 2001, Renjifo et al. 2002). It is much less common near Amalfi, presumably because the forests in this area have been subjected to exploitation for a longer period of time (Renjifo et al. 2002). |

Conservation and Research Actions Underway
The species is classified as Critically Endangered in Colombia and listed as 8th in the top ten most threatened species in Colombia (Cuervo 2014, Fundación ProAves 2014, D. Lebbin in litt. 2015). La Reserva Natural La Forzosa, a fragment of pristine forest of 4.5 km2 between 1,500 and 1,820 m, has been designated following an ornithological exploration of the area (Cuervo et al. 2001, Renjifo et al. 2002). 1,310 acres of forest were purchased by the American Bird Conservancy to be managed by Fundación ProAves as the Arrierito Antioqueño Bird Reserve in 2006 (Anon 2006/2007). It is also found in La Serrana and Caracolí-Guayabito reserves (Cuervo 2014). These reserves protect a suite of bird species of conservation concern in addition to L. weberi (Sharpe 2015).
Conservation and Research Actions Proposed
Conduct detailed surveys to determine the extent of its distribution, population status, and genetic variation and exchange between the Amalfi and Anorí populations (Renjifo et al. 2002). Develop a management plan for the species. Pursue the protection of remaining pre-montane forest fragments in the region, particularly those persisting in the Riachón river valley in Amalfi (Renjifo et al. 2002). Control exploitation of palms and other forest resources. Encourage the local government to acquire land between 1,200 and 1,600 m for future protected areas. Encourage alternative technologies for the use of the land, and campaign to prevent the conversion of forests to pastures (Renjifo et al. 2002). There remains some large intact and potentially suitable subtropical forest areas in eastern and southeastern Antioquia. Conservation efforts in these areas may prove more practical and probably reveal healthy populations of this and other threatened species (Salaman in litt. 2003, Sharpe 2015). Protect Bosque El Guayabito from deforestation (Fundación ProAves in litt. 2012). Connect fragmented habitats where the species is known to occur (Snow and Sharpe 2015).
