This study tested the hypothesis that T3 (triiodothyronine) is the tissue-active "seasonality" hormone by determining whether T3 could mimic T4 (thyroxine) and program photostimulated thyroidectomized (THX) male American tree sparrows (Spizella arborea) for three components of seasonality (i.e., ful
