Conservation

Conservation Status

The conservation status of Common Diuca-Finch is assessed by the IUCN Red List as "Least Concern" (BirdLife International 2015). It received this categorization due to its extremely large estimated range, 1,570,000 km2, and, although its population size has not been quantified, its population has been described as stable. Parker et al. (1996) considered this species of "low" conservation priority relative to other Neotropical birds.

Effects of human activity on populations

Parker et al. (1996) considered Common Diuca-Finch to have a "low" degree of sensitivity to human disturbance relative to other Neotropical birds. It is known from the following protected areas: Argentina: Parque Nacional (PN) Los Cardones, PN Talampaya, PN Fray Jorge, Reserva de Ñacuñán (Mezquida 2003, eBird 2012); Chile: Reserva Nacional (RN) Las Chinchillas, PN Hornopirén (eBird 2012). Its foraging strata includes the ground of farmlands, eating mainly seeds that have fallen, and, as it does not disperse seeds, it is of no known agricultural concern (Jaramillo 2011). Intensive agriculture has been shown to decrease the population sizes of birds, especially since 1990. It is unknown how severe these populations decreases are in many species, as well as what the compounding effects of this and climate change are, but Common Diuca-Finch potentially is at risk due to agriculture being part of its habitat (Jaramillo 2011).
