The mourning sierra finch (Rhopospina fruticeti) is a species of bird in the family Thraupidae, the tanagers and allies. It is found in Argentina, Bolivia, Chile, and Peru and has been recorded as a vagrant to Brazil and the Falkland Islands.
The mourning sierra finch was formally described and illustrated in 1833 by the German naturalist Heinrich von Kittlitz with the binomial Fringilla fruticeti. The species was later reassigned to the genus Phrygilus. Both the genera Fringilla and Phrygilus were in the finch family Fringillidae but multiple studies published in the early 2000s showed that Phrygilus belonged in the tanager family Thraupidae. A molecular phylogenetic study published in 2014 found that Phrygilus was polyphyletic, and in the subsequent rearrangement, the mourning sierra finch was moved to the resurrected genus Rhopospina that had been introduced in 1851 by Jean Cabanis. The genus name combines the Ancient Greek rhōps meaning "bush" with spina meaning "finch". The specific epithet is from the Latin fruticetum meaning "thicket".

Rare
Under 5% of wildlife watchers report a Mourning Sierra-Finch sighting in Arequipa on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 42nd most-seen of the 61 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Mourning Sierra-Finch in Arequipa on a given day, against under 5% in July to April, the lowest months. Those are among Arequipa's driest months, with almost no rain against 45 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Mourning Sierra-Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Mourning Sierra-Finch sightings, Arequipa ranks 3rd at under 5%. The best odds are in Santiago (Chile, about 10%) and La Paz (Bolivia, about 10%).
GBIF citizen-science records
It is estimated from how often the Mourning Sierra-Finch is recorded against all the birds logged in Arequipa (21 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
