Spinus siemiradzkii
The Saffron Siskin (Spinus siemiradzkii) is a striking and geographically restricted passerine belonging to the finch family Fringillidae, notable for its vibrant plumage and specialized dry forest habitat. Males are particularly conspicuous, boasting a brilliant saffron-yellow body contrasted sharply with a glossy black cap, black wings adorned with two distinct yellow wing-bars, and a black tail. Measuring approximately 10.5 to 11.5 cm (4.1-4.5 inches) in length and weighing around 9-12 gra...
The Saffron Siskin primarily inhabits arid to semi-arid inter-Andean valleys, favoring dry deciduous forests, thorny scrublands, and forest edges. It can be found at elevations typically ranging from 300 to 2,000 meters (1,000-6,500 feet) above sea level.
The Saffron Siskin feeds primarily on small seeds, particularly those derived from arid zone shrubs and trees, with a strong preference for *Acacia* species. They typically forage by gleaning seeds directly from seed pods and catkins while perched acrobatically.
Saffron Siskins are diurnal, typically foraging actively throughout the day and roosting inconspicuously within dense foliage at night. Their foraging strategy involves acrobatically clinging to thorny bushes and small trees to extract seeds from catkins and seed pods, often hanging upside down l...
The Saffron Siskin's geographical distribution is highly restricted, primarily confined to specific arid and semi-arid inter-Andean valleys of southwestern Ecuador and northwestern Peru. In Ecuador, its range extends through the provinces of Guayas, El Oro, Loja, and Azuay, typically in the dryer...
