Red factor canary

The red factor canary averages about 5+1⁄2 inches (14 cm) in length.

It was developed as a cross between another type of finch — the now-endangered Venezuelan red siskin (Spinus cucullatus) — and a yellow domestic canary (Serinus canaria domestica).

[2][3] In breeding/showing, domestic canaries are broken down into two types based on pigmentation: melanics[4] and lipochromes.

Intensive red factors are characterized by even lipochrome distribution throughout their feathers, giving the plumage a bright and uniform appearance throughout.

Birds with non-intensive coloration have feathers that lack pigmentation at the tips — referred to as frosting due to the appearance — this makes for a more subdued brightness in appearance than birds with intensive coloration.
