Yellow
A variant of Domestic canary (Serinus canaria forma domestica)
The classic clear-yellow canary, fixed centuries ago from the wild greenish serin. The default 'canary yellow' and the easiest entry bird in the hobby.
Keeper tips for this variant
A genuinely beginner bird — a single cock in a roomy cage with good seed/egg-food and 10-12 hours of consistent light will sing readily; no special color feeding needed.
