This dataset contains measurements of four physiological parameters measured in blood samples collected from zebra finches held in indoor cages over a period of 4 months. We measured four parameters: glucose concentration, non-enzymatic anti-oxidant capacity, lipid peroxidation and relative telomere length. Zebra finches were held in groups separated into three different treatments: a control group where birds were held under natural light-dark cycles, a group where birds were exposed to dim artificial light at night during the entire night (FLAN) and a group where birds where partially exposed to artificial light at night, between dusk and midnight (PLAN). Samples were taken at the start, mid-term, and end of the experiment. Full details about this nonGeographicDataset can be found at https://doi.org/10.5285/55f10059-82c0-4216-a004-e6d690d628e1
