Metabolic adjustments of a wild passerine to acute stress and heat acclimation

Data were collected during a study on Arizona House Finches in which we compared morphological characteristics, food intake, and blood metabolite concentrations in a CONTROL group (COLD group, C) with those in a heat-exposed group (HOT group, H). Data were collected for each bird at the time of capture (morphology only) and in captivity, before (PRE-TREATMENT) and then one and two weeks after birds were randomly assigned to the COLD or the HOT treatment. In addition, blood metabolite concentrations were measured at baseline and again after 30 min of handling/mild restraint stress.
