Common Diuca-Finch Diuca diuca



Conservation Status

The conservation status of the Common Diuca-Finch has been listed 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 population size has not been quantified, it 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 the Common Diuca-Finch to have a “low” degree of sensitivity to human disturbance relative to other Neotropical birds. Diuca diuca 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). Their foraging strata includes the ground of farmlands, eating mainly seeds that have fallen down and they do not disperse seeds, so they are 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 the Common Diuca-Finch is potentially at risk due to agriculture being part of its habitat (Jaramillo 2011).
