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.

Cowbirds get a bad rap for making other birds raise their young, but @thecowbirdlab.bsky.social, ornithologist and executive director of the CUNY ASRC, and his lab have revealed — study by study — why you should put some respect on the parasites' name. bit.ly/3LmC22U

Got Beef With Cowbirds? This Researcher Wants to Change Your Mind

The brood parasites get a bad rap for making other birds raise their young, but study by study, Mark Hauber and his “Cowbird Lab” have revealed a species worthy of respect.
