Energetic profile of Melopsittacus undulatus. Top Relationship of energy expenditure at rest (SMR = 80.0 − 2.0T A, R 2 = 0.96; BMR = 26.0 ± 0.7, kJ per day) to ambient temperature (T A, °C) according to Scholander’s model and changes in the energy equivalent of lost body mass (q = 30.5 − 0.65T A, R 2 = 0.93, kJ per g). Each value is a mean for several measurements in several birds at given T A, vertical lines ± SD. Bottom. Relation evaporative heat loss (H e, kJ per day), non-evaporative heat loss (H s, kJ per day) and percentage of heat loss through evaporation (H e,  %)—to ambient temperature (T A, °C) in Budgerigar, Melopsittacus undulatus in summer
