W. Hagelberg's zoologischer Hand-Atlas              
was published between 1879-1881. The second part (Part B) includes the part AVES. It’s a collection of 285 rare bird illustrations read more>
1. HEAD Usual abbreviations in publications are inter alia: R.T.B. = Red Tipped Beak ( e.g. BH R.T.B. = Black Red Tipped Beak) Y.T.B. = Yellow Tipped Beak Red head  = sex-linked dominant Black Head = sex-linked recessive Orange Head = autosomal recessive
3. Chest/Breast: Purple Chest = autosomal dominant (dominant for lilac and white breast) White Chest  = autosomal recessive Lilac Chest =  (1.) To the purple chest is the lilac chest autosomal                         recessive heritable.                         (2.) To the white chest is the lilac chest autosomal                         dominant heritable. The lilac chested gene is                         probably an allele of the white chest. Blue Chest = autosomal recessive (the fact that it is a true                        established mutation is currently (2018) not proven)
4. Currently only available in Australian (Note: Since 01.01.1960 Australia banned the export of every avian from the origin of Australia. This is the reason why Australian mutations are not outside from Australia available). Australian Blue = autosomal recessive Australian Yellow (first named ”Australian White Breasted Yellow”) = autosomal recessive Australian (Aussie) Variegated Blue (AVB)  = autosomal recessive Austalian Lime (Dilute Green) = sex-linked recessive (same genetic as the Australian Lutino) Australian Lutino = autosomal recessive Australian Pastel = autosomal recessive Australian Dilute Back =  autosomal recessive (Note: The Green Backed Dilute is a secondary-coloured mutation of the Dilute) 5. Currently only available in Cuba (Note: As far as know, theCuba mutations are currently only by one breeder in Cuba available.) Cuban Lutino = sex-linked recessive Cuban Lutino Pastel = [sex-linked recessive]
NOTE: The listing does probably not claim to be complete. Among other things, there are more recent reports published about new colour appearances in gouldian finches, whose inheritance is not yet determined and therefore not sure whether they are real mutations or just modifications. (status 2018)
2. BODY Green = sex-linked dominant (and sex-linked co-dominant to Dilute) Dilute / Yellow = sex-linked co-dominant to the Green Cinnamon = sex-linked recessive Blue = autosomal recessive Pastel-Blue / Silver = sex-linked co-dominant (Aqua) Seagreen = autosomal recessive (Aqua) Seagreen or Ivory (named from C.O.M.) = sex-linked recessive Fallow = autosomal recessive (The Fallow gene is present in small numbers in Japan and possibly some European countries. The Fallow gene produces red eyed Green Gouldians. When combined with the Pastel Green and Blue genes, the Fallow gene can produce a Gouldian which looks like a true Lutino. Dark Factor = autosomal dominant In the green series it is called: Dark Green (Laurel Green) = single-factor (SF) dark Olive Green = double-factor (DF) dark In the blue series it is called: Cobalt = single-factor (SF) dark Mauve = double-factor (DF) dark Lutino / Albino = sex-linked recessive (Note: In past history of the Ino mutation’s there has been a sex-linked and autosomal recessive mutation. The majority if not all ino's today are only sex linked.)
