Black-Hooded Siskin Mutation

The hooded siskin (Spinus magellanicus) is a small, vibrant finch from South America, often recognized by its striking coloration and lively song. Males of this species feature a predominantly green upper body, vivid yellow undersides, and a black head, accented by a yellow collar and rump. The black wings and tail are contrasted by yellow highlights, adding to the bird’s distinct appearance. Females are less colorful, displaying a green-brown head, yellow-green breast, and a lighter belly.

This adaptable finch inhabits diverse environments, from woodlands and savannas to farmland and gardens, and can be seen from sea level up to altitudes of 5,000 meters. Its range extends across eastern and Andean South America, reaching from Argentina and Brazil to central Colombia, with isolated populations in regions like southeastern Venezuela and Guyana.

Hooded siskins typically form flocks and feed on seeds, buds, leaves, and occasionally insects, engaging in geophagy (soil ingestion) to obtain essential minerals. Their energetic, twittering song is often heard from a perch or while in flight and may even mimic other bird species. The Santa Cruz hooded siskin (S. m. santaecrucis), found in Bolivia, is a notable subspecies that some taxonomists consider a separate species due to its unique characteristics.
