Conservation and survival

The global population size of the yellow-rumped siskin (Spinus uropygialis) has not been quantified. The overall population trend of the species is reported to be stable.

In most of its range, this siskin species is reported to be fairly common but patchily distributed (Stotz et al. 1996). The generation length is 4.2 years. Its distribution size is about 216,000

Ecosystem degradation, ecosystem conversion, deforestation, human activities in the breeding range and capture of adults and juveniles for pet-trade are the main threats that may endanger the survival of the species.
