将三只家鸡分别饲养在22℃的气候室中，0600时开灯，1800时常开灯。食物和水随时可用。中午，一只鸟被抓去泄殖腔。每 3 分钟梳理一次脚部温度，持续 18 分钟。反复处理会产生发烧，其特征是核心温度平均从 41.1 +/- 0.3 摄氏度升高到 41.6 +/- 0.3 摄氏度，并且最初外周血管收缩，如皮肤温度下降所示。当家禽在处理前一小时腹腔注射水杨酸盐时，最高核心温度仅为 39.9 +/- 0.2 摄氏度。结论是处理会导致鸟类发烧。这些鸟配备了心电图无线电发射器，并在远处记录它们的心率。当实验者简单地触摸时，鸟儿的平均心率从 198 +/- 6 次/分钟上升到 249 +/- 15 次/分钟。我们得出的结论是，杠杆和心动过速可能表明鸟类存在情感。 (C) 2000 Elsevier Science Inc. 保留所有权利。
Three Gallus domesticus cocks were reared separately in a climatic chamber at 22 degrees C, with lights on at 0600 and oft at 1800 h. Food and water were available at all times. Ar noontime, one bird was handled fur the purpose of taking cloacal. comb, and foot temperatures every 3 min for 18 min. Repeated handling produced a fever characterized by a mean rise in core temperature from 41.1 +/- 0.3 degrees C to 41.6 +/- 0.3 degrees C and an initial peripheral vasoconstriction, as shown by a drop in skin temperatures. Maximum core temperature was only 39.9 +/- 0.2 degrees C when the birds received intraperitoneal salicylate I h before handling. It is concluded that handling causes a fever in birds. The birds were equipped with an electrocardiogram radio transmitter, and their heart rates were recorded at a distance. When simply touched by an experimenter, the birds' mean heart rate rose from 198 +/- 6 to 249 +/- 15 beats/min. We conclude that lever and tachycardia might indicate the existence of emotion in birds. (C) 2000 Elsevier Science Inc. All rights reserved.
