Three Basic Feather Patterns from Coloured, Type & Song Canaries

It’s hard to talk about color without also discussing the 3 feather types which although are not distinct colors, do in fact alter what we think we see!!!! As with base colors, all canaries are 1 of the 3 feather types . The 3 feather types are Intensive, Frost (non-intensive) and Mosaic. Frost is self descriptive. Each feather on the frost example is tipped with white giving the bird an appearance of being drowned in confectionary sugar. An intensive bird does not have this white tip. Lastly a mosaic is unique in that it has a much wider white tipping on certain areas of the body and NOT on others… that is why it has a red mask and red shoulders and not a red body! (Note; male mosaics show more red color than females, as it is a dimorphic factor)
