Donacospiza albifrons
The Long-tailed Reed Finch, *Donacospiza albifrons*, is an enigmatic and elegant passerine that, despite its common name, is actually classified within the tanager family (Thraupidae), making it a fascinating example of convergent evolution. Measuring approximately 15-16 cm (6-6.3 inches) in length and weighing around 15-20 grams (0.5-0.7 oz), it is distinguished by its proportionately long, dark tail with noticeable white outer rectrices, particularly evident in flight. Adults feature a stri...
Primarily inhabits dense reedbeds, wet grasslands, marshes, and humid savannas, typically found in lowland areas up to approximately 1500 meters (4,900 feet) near water sources.
Primarily granivorous, feeding on small seeds from various grasses and reeds, supplemented with insects, especially during the breeding season.
This diurnal species is often observed singly or in pairs, though small family groups or loose associations can form outside the breeding season. It is a skulking bird, frequently staying hidden within dense vegetation, making it more often heard than seen. Foraging involves gleaning seeds, parti...
The Long-tailed Reed Finch is endemic to south-central South America, with a distribution encompassing southeastern Bolivia, Paraguay, Uruguay, northeastern Argentina, and southern Brazil. Its breeding range largely overlaps with its year-round residency, as it is generally considered a resident ...
Least Concern
- Despite its common name, the Long-tailed Reed Finch is not a true finch (family Fringillidae) but belongs to the tanager family (Thraupidae), making it an interesting case of convergent evolution. - It is the sole species within its genus, *Donacospiza*, highlighting its unique ecological niche...
