In order to understand the ecophysiological characteristics of the crested mynas(Acridotheres cristatellus) inhabiting in relative warm area,the metabolic rates(MR),body temperatures(T_b),and thermal conductance(C) at temperature range of 5.0-37.5℃ was measured.Adult mynas were live-trapped by mist net in the Wenzhou city,Zhejiang Province(27°29′ N,120°51′ E) from September to November 2008.Eight crested mynas(four males and four female) were used in this experiment.Body masses to the nearest 0.1 g were determined immediately upon capture with a Sartorius balance(model BT25S).The mean body mass of crested mynas was 117.7 ± 3.4 g.Birds were transported to the laboratory and caged(50 cm × 30 cm × 20 cm) under natural photoperiod and temperature.Food and water were supplied ad lib.MR was measured by using closed circuit respirometer,and temperature was controlled by water bath(± 0.5℃),T_b was measured by insertion of a digital thermometer(Beijing Normal University Instruments Co) into the cloaca,and C was calculated at each temperature below the thermal neutral zone using the formula: C=MR /(T_b-T_a),where T_a is ambient temperature.The thermal neutral zone of mynas was 25.0-32.5℃.The mean metabolic rates within thermal neutral zone of crested mynas were 125.33 ± 2.08 ml O₂ /h,which are 60% of the expectedvalue from their body mass.Mean T_bs of mynas were 41.4 ± 0.1℃.Cs of mynas were 0.06 ± 0.00 ml O₂ /(g.h.℃),100% of the expected value based on their body mass.Below the lower critical temperatures MR increased with declining T_a and the regression equations relating MR to T_a was described as: MR[ml O₂ /h]= 365.30-10.07T_a(℃).The ecophysiological characteristics of crested mynas are: low basal metabolic rate,relatively high body temperature and high thermal conductance.These properties might make them acclimatized to their environments and survive at relative warm temperature areas for this species.
