Population justification: The breeding population, which is confined to Europe, is estimated at  4,975,000-6,850,000 pairs, which equates to 9,950,000-13,700,000 mature individuals (BirdLife International in prep.).

Trend justification: The population is believed to have declined at a rate of 20-29% over ten years (the species's generation length is 2.1 years; Bird et al. 2020), due to the effects of agricultural intensification, habitat conversion, over-hunting and the effects of high volume release of farm-reared birds, many of which proved to be hybrid A. chukar x A. rufa (Blanco-Aguiar et al. 2008, Barbanera et al. 2010).
This is a lower rate of population reduction than the 40-45% in ten years reported by EU Member States to the European Commission under Article 12 of the EU Birds Directive (BirdLife International in prep.), or the 44% in ten years since 2008 reported under the Pan-European Common Bird Monitoring Scheme. There is a high likelihood that population monitoring in the core range of the species was incomplete, as this species is managed for hunting on large privately-owned estates that were inaccessible to the surveyors. Red-legged Partridge is the most economically important small-game species in central Spain, and 87% of hunting estates, holding a large proportion of the population, are privately owned (Díaz‐Fernández et al. 2012).
However, these populations are not considered immune to the declines occurring throughout the rest of the range, and while there is scope for good management to maintain viable populations with a hunting surplus, it is suspected that these populations are also undergoing a moderate population reduction.
