Magdalena Antbird Sipia palliata



Justification

Justification of Red List category
This species is listed as Near Threatened on the basis that its population is suspected to be undergoing a moderately rapid decline owing to ongoing habitat loss and degradation, driven primarily by agricultural expansion.

Population justification
The global population size has not been quantified.

Trend justification
There are no data on the population trend, but declines are suspected owing to ongoing habitat destruction and degradation (del Hoyo et al. 2003).Within the range, 6% of tree cover has been lost over the past ten years; this has been accelerating to a rate equivalent to 8% over ten years since 2017 (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). These values refer to tree cover loss alone and do not account for forest degradation and fragmentation; consequently, the overall rate of habitat loss is likely higher. A projection of deforestation and habitat loss based on several predictor values found a similar pattern of accelerating habitat loss between 2015 and 2040, to a rate equivalent to 31% over ten years (Negret et al. 2021).
The species has specialised habitat requirements and is considered highly susceptible to forest loss and degradation. Therefore, while the rate of decline has not been quantified and there is considerable uncertainty about the overall rate of habitat loss across the range, declines are here tentatively placed in the band 20-29% over ten years.

Distribution and population

Sipia palliata has a patchy distribution in north and north-central Colombia on the northern slope of the Andes and in the Magdalena valley, and in northwestern Venezuela in the Sierra de Perijá and Cordillera de Mérida.

Ecology

It inhabits humid and wet forests, mostly in the foothills, where it is most numerous, but also ranges down into the lowlands and up into lower montane habitats in some areas (Hilty and Brown 1986, del Hoyo et al. 2003). It is mainly terrestrial and is found in dense understory and on the forest floor, where it prefers damp, shady ravines and slopes along streams (del Hoyo et al. 2020). It seems to have only a limited tolerance of habitat fragmentation and degradation (T. Donegan in litt. 2011, del Hoyo et al. 2020).

Threats

This species occupies a region that is subject to extensive land-use change. The middle and lower Magdalena valley has been extensively deforested since the 19th century for agriculture and coffee plantations, and clearance of its foothills has been near total since the 1950s (Forero 1989). The species is increasingly exposed to human encroachment and disturbance, which is projected to continue (Ocampo-Peñuela et al. 2022).

Conservation actions

Conservation Actions Underway
No targeted conservation actions are known for this species, although some of its habitat receives various levels of protection.

Conservation Actions Proposed
Carry out wide-ranging surveys to obtain a total population estimate. Study the species' life history and habitat requirements. Monitor the population trend. Monitor rates of habitat loss and degradation within the species' range. Increase the area of suitable habitat that receives effective protection.
