The Eumo Zebra finch has become a very popular and highly sought-after mutation of a zebra finch in the last few years, both for its very attractive appearance and the great possibilities provided by combinations with other mutations in colors and markings.

The name Eumo is derived from the term “eumelanin”, which marks the main characteristic of this almost black Zebra finch. A dark, melanising mutation. To describe the Eumo Zebra finch mutation would not be possible without knowing eumelanin. Eumelanin consists of black, but also of dark brown, brown and gray eumelanin, which results in black or dark brown feathers. Pheomelanin is reddish brown in color and it is present in the cheeks and flank markings in male Zebra finches.
