Demography and Populations

Saffron-billed Sparrow is categorized as fairly common relative to other Neotropical birds (Parker et al. 1996).

Diseases and body parasites:

Saffon-billed Sparrow is known to host the larvae of the tick species
Haemaphysalis leporispalustris, Haemaphysalis juxtakochi, and Ixodes pararicinus (Beldomenico et al. 2003, Pascoli 2005, Flores et al. 2014). They are also known to host both larvae and nymphs of Amblyomma longirostre, Amblyomma nodosum, and Amblyomma clacaratum (Pascoli 2005, Sanches et al. 2012). Saffron-billed Sparrow is also known to be infected with Chlamydia (Ribeiro et al. 2013).

Dispersal:

Nores and Cerana (1990) concluded that Saffron-billed Sparrows do not live outside of forest, or shrub connected to forest, and cannot disperse except through forested habitat corridors. However, Marini (2010) reported that the species was able to effectively disperse ≥ 1500 m among forest patches within an open savanna matrix (Marini 2010).
