White Breasts also can have these red lines.

Due to our breeding methods a lot of our birds lost this characteristic.
Genetic inheritance should be autosomal recessive.

Such birds also appear in nature which proves this red line isn't the result of some photographic process.

To prove that this bird existed in the past, we are publishing a color plate of an unknown artist from the work "A Popular History of Birds, A Familiar Account of their Classification and Habits" from Adam White. London 1855.
In this work our Gouldian Finch is yet described as Poephila Mirabilis.
