Electrographic and behavioural observations were conducted on two male and two female captive starlings (Sturnus vulgaris) under natural illumination conditions during autumn. Polygraphically sleep and wakefulness of starling were similar to those of other birds. Starling's total sleep (TS) and slow wave sleep (SWS) lasted 39.0 +/- 1.4% and 38.3 +/- 1.7% of the 24-h period respectively. Paradoxical sleep (PS) was 1.8 +/- 0.2% of the total sleep time. The mean durations individual of TS, SWS and PS episodes were 6.8 +/- 0.2 min, 5.0 +/- 1.0 min and 18 +/- 3 s respectively. The daily percentage of SWS was correlated with the mean episode duration while that of PS was correlated with the number of episodes rather than with the mean episode duration. Starling females spent in sleep a greater percentage of the 24-h period than males.
在秋季自然光照条件下，对两只雄性和两只雌性圈养椋鸟（家八哥）进行了脑电图和行为观察。椋鸟的多导睡眠图显示，其睡眠和清醒状态与其他鸟类相似。椋鸟的总睡眠时间（TS）和慢波睡眠时间（SWS）分别占24小时周期的39.0±1.4%和38.3±1.7%。异相睡眠时间（PS）占总睡眠时间的1.8±0.2%。TS、SWS和PS发作的平均时长分别为6.8±0.2分钟、5.0±1.0分钟和18±3秒。SWS的每日占比与平均发作时长相关，而PS的占比与发作次数相关，而非与平均发作时长相关。雌性椋鸟在24小时周期内用于睡眠的百分比高于雄性。
