|Taxonomic Notes:||Thryophilus sernai (del Hoyo and Collar 2016) is recognized as a species following work by Lara et al. (2012).|
|Red List Category & Criteria:||Endangered A3c+4c ver 3.1|
|Reviewer(s):||Butchart, S. & Symes, A.|
This species is listed as Endangered because it has a very limited range which is under imminent threat from habitat loss, in particular as a result of the construction of a dam which is projected to lead to the loss of >50% of its habitat.
|Previously published Red List assessments:|
|Range Description:||Occurs in the northern part of the Cauca Valley (Ituango S to Concordia/Salgar border) in Antioquia (NW Colombia).|
Native:Colombia (Colombia (mainland))
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||The population size has not been quantified and it may not be possible to make an overall population estimate based on the availability of habitat for breeding, because of the absence of this species in many areas where conditions seem to be suitable (O. Cortes-Herrera in litt. 2016).|
Trend Justification: The species is suspected to be declining as a result of historical and continuing habitat alteration (Lara et al. 2012), as land has been converted for mining, agriculture, pasture and urban areas (Lara et al. 2012). Additionally, a large amount of its range (c.53%) may be lost to flooding due to construction of the Pescadero-Ituango hydro-electric dam (Lara et al. 2012) due for completion in 2018.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is probably only found in semi-decidous dry forest habitat with an open understorey (Lara et al. 2012, Fjeldså 2016).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||3.9|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||The species is suspected to be declining as a result of historical and continuing habitat alteration (Lara et al. 2012), as land has been converted for mining, agriculture, pasture, road construction and urban areas (Lara et al. 2012, O. Cortes-Herrera in litt. 2016). Additionally, a large amount of its range may be lost to flooding due to construction of the Pescadero-Ituango hydro-electric dam (Lara et al. 2012) due for completion in 2018. The predicted extent of the reservoir would represent c.53% of its habitat being affected just by this threat.|
Conservation Actions Underway
Conservation Actions Proposed
Assess more thoroughly the projected large impact that the reservoir's construction will have on this species, and investigate and implement any possible actions that could limit the severity of the impact on this species as soon as possible.
