question about lights

[fitos100]

Hi, I readed in many articles that artificial daylight in aviaries should be extend until 12-13 hours, so it can trigger the breeding mood.
But As I see from the charts, gouldians in nature are breeding during late summer, autumn and early winter. So what I understand the daylight getting shorter.
What am I missing here?

The long days of sunlight are at the beginning of the breeding cycle, and slowly decrease over the time as they run down and stop. I persume the suggestion is that you have 8/9hr days in winter, 10/11 hr days in Spring and Autumn and 12/13 hr days in Summer. This would be roughly = to what happens in their natural habitat.

Hello Fitos, I do not think day light length is an important factor in Gouldians breeding, certainly not in the highly domesticated variants we keep in aviaries.
Even the wild birds, coming from a tropical climate the day light does not vary much in length.
If you let them they will breed all year round.
The problem with shorter days is that the birds have less daylight to feed the chicks
