Oxygen-free metabolism in the bird inner retina supported by the pecten - Nature While the photoreceptor outer segments in the bird outer retina have access to oxygen, the inner retina operates under chronic anoxia, supported by anaerobic glycolysis in the retinal neurons.

Bird retina uses anaerobic glycolysis for energy!!

Probably cold tolerance, but maybe also flight endurance.

Snowfinches actually had a totally different phenotype than high-elevation sparrows, with more capillaries in their heart to enhance oxygen supply.

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.
