Key Identification Features
- The golden-winged sparrow, scientifically named Arremon schlegeli Bonaparte, 1850, can be identified by its black head, long yellow bill, gray upperparts, and a green patch on its back.
- Juvenile rufous-collared sparrows have a duller, less distinct head pattern, with brown stripes and a buff base colour.
- This form may be distinct enough to be classified as a separate species, or it may simply be a particularly distinct population resulting from genetic bottleneck effects.
- Young birds have yellower underparts and a duller, less distinct head pattern.
