They suggested checking with Cornell Lab of Ornithology as a source of
info but apparently they only cover wild birds, not pet birds kept
indoors.
So does anyone know a definitive scientific source of info for how
lighting affects indoor pet birds, and what they need, from a scientific
source that's not involved in selling merchandise based on their info?
This is fascinating to me.
I'm doing a Google on: pet birds light spectrum science
and finding only sites that are selling stuff too.
