Relevant Data for "Nomadic songbirds achieve rapid increases in thermogenic capacity during cold acclimation while maintaining low corticosterone". Jessica Karr (24896446) Comparative physiology crossbills metabolism thermoregulation flexibility <p dir="ltr">Here, we investigate metabolic flexibility of the red crossbill (<i>Loxia curvirostra</i>), a nomad that experiences wide variability in climate, to determine how flexibility in migration relates to thermogenic flexibility. Two ecotypes of captive red crossbill (Type 3 and Type 5) were transferred to thermoneutral (21°C) or cold (6°C) temperatures during their spring migratory period. Metabolic rates and baseline corticosterone levels were repeatedly measured across nine days during acclimation. A subset of birds were used as controls to look for evidence of cold training in the thermoneutral group. Thermogenic capacity, BMR, and baseline corticosterone were measured along with metrics of body composition on various days. The full description of these methods can be found in the Journal of Comparative Physiology B. Please look through the ReadMe file that explains the breakdown of each data set, and any data that was removed prior to analysis. </p> 2026-09-15T12:12:11Z Dataset Dataset 10.6084/m9.figshare.33752656.v1 https://figshare.com/articles/dataset/Relevant_Data_for_Nomadic_songbirds_achieve_rapid_increases_in_thermogenic_capacity_during_cold_acclimation_while_maintaining_low_corticosterone_/33752656 CC0 Open Access after 2026-12-01
