Data Zone
Justification of Red List category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).
Trend justification
The population trend has not been investigated, but the only threat known to the species is the logging and fragmentation of forests within the range. Tree cover loss within the range is very low (2% over three years; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Apart from forests, the species is sometimes also found in dense secondary scrub (Schulenberg and Jaramillo 2020); consequently, the current rate of tree cover loss may not be affecting the population. Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
Arremon abeillei is found in southwestern Ecuador (from Manabí) south along the Pacific coast to northwest Peru (south to Lambayeque and Cajamarca).
It inhabits forest understory and sometimes dense scrub (Schulenberg and Jaramillo 2020).
Due to the species' preference for forests, it is vulnerable to the loss and degradation of habitat, mainly through logging and expansion of agriculture and livestock pastures.
