据报道，成年鸵鸟的快速眼动睡眠（REM）时间最长（长达5分钟），REM睡眠时间最长（占夜间时间的24%），是其他鸟类中最长的。如果在鸵鸟中存在哺乳动物的个体发生趋势，那么在年轻的鸵鸟中快速眼动的数量和睡眠的持续时间可能比在成年鸵鸟中报道的要长。我们研究了1.5-3.5月龄鸵鸟雏鸟的睡眠。记录时间为夜间（20:00-08:00），为鸵鸟的主要睡眠时段，为昼间睡眠。与其他鸟类研究一样，在清醒、非快速眼动（NREM）睡眠和快速眼动（REM）睡眠时，以4秒为周期对polygram进行评分。鸵鸟雏鸟的快速眼动睡眠发生在皮层脑电图激活和慢波期间，正如在成年鸵鸟中所描述的那样。雏鸡69.3%±1.5%的时间处于非快速眼动睡眠状态。快速眼动睡眠占夜间睡眠的14.1%±1.8%或16.8%±2.0%。快速眼动睡眠平均持续10±1秒，时间在4 ~ 40秒之间。因此，鸵鸟雏鸟的快速眼动睡眠的总时间和持续时间明显小于成年鸵鸟，而非快速眼动睡眠的时间没有太大差异。鸵鸟快速眼动睡眠个体发生的发育特征可能与所有研究过的哺乳动物和鸟类有显著不同。
It has been reported that adult ostriches displayed the longest episodes of rapid eye movement (REM) sleep (up to 5 min) and more REM sleep (24% of the nighttime) than any other bird species. If the mammalian ontogenetic trend exists in the ostrich, then the amounts of REM and the duration of sleep episodes in young ostriches may be greater than those reported in adults. We investigated sleep in 1.5–3.5 month old ostrich chicks. Recordings were conducted during nighttime (20:00–08:00), the main sleep period in ostriches, which are diurnal. The polygrams were scored in 4-s epochs for waking, non-rapid eye movement (NREM) sleep and REM sleep, as in other bird studies. REM sleep in ostrich chicks occurred during both cortical EEG activation and during slow waves, as was described in adult ostriches. The chicks spent 69.3% ± 1.5% of the night in NREM sleep. REM sleep occupied 14.1% ± 1.8% of the night or 16.8% ± 2.0% of nighttime sleep. Episodes of REM sleep lasted on average 10 ± 1 s and ranged between 4 and 40 s. Therefore, the total amount and duration of REM sleep episodes in ostrich chicks were substantially smaller than reported in adult ostriches while the amounts of NREM sleep did not greatly differ. The developmental profile of REM sleep ontogenesis in the ostrich may be remarkably different from what has been reported in all studied mammals and birds.
