Demography and Populations

There are few quantitative data on its abundance or on population trends, or on survivorship. The species is often described as being ‘uncommon and local’ (Ridgely and Tudor 1989, Fjeldså and Krabbe 1990, Parker et al. 1996). One detailed study from the fragmented Polylepis woodland landscapes in the Cordillera Vilcanota, southern Peru, estimate densities of Short-tailed Finch at 4.5 ± 75.6 individuals per km² Polylepis woodland (Lloyd 2008). Encounter rates (number of individuals per point count) used as a measure of relative abundance, were greater in the smaller woodland patches (0.19 ± 0.39), than in either medium (0.07 ± 0.26) or large (0.01 ± 0.10) woodland patches (Lloyd 2008).
