Timing programs in animal migrants have been selected to synchronize movements that coincide with predictable resources on the breeding and nonbreeding grounds. Migrants face potential temporal conflicts if their migration schedules benefit from synchrony to conflicting rhythms associated with annual biogeographical (circannual) cues, lunar (circalunar) cues, or individually-repeatable internal clocks. We repeat-tracked individuals of an avian lunaphilic species, Eastern Whip-poor-will (Antrostomus vociferus), for 2â3 successive autumn migrations to determine the influence of the lunar cycle, breeding location, and individual repeatability on migration timing. Almost all birds avoided departing for migration during a full moon, likely to take advantage of the bright moonlight to facilitate visual foraging and enhance pre-migration fattening. However, groups from two latitudinally-distant sampling areas adjusted their autumn departure timing differently relative to the timing of the Sept..., , , # Lunar synchrony, geography, and individual clocks shape autumn migration timing in an avian migrant
* all data are GPS locations and dates used for the investigation of the influence of full moon, sampling location, and individual repeatability on whip-poor-will autumn migration timing
* all data are from adult male whip-poor-wills
* data have been summarized from a more comprehensive GPS tracking dataset; these data have been filtered to include only the necessary data used in analyses
* Antrostomus vociferus is currently listed as \"Near-threatened\" by the IUCN. Therefore, no GPS locations for exact breeding sites are included in the dataset. Locations in the departure dataset are for the first lat/lon recorded after each bird departed its breeding site

CatMeows
该数据集包含440个声音样本，由21只属于两个品种（缅因州库恩猫和欧洲短毛猫）的猫在三种不同情境下发出的喵声组成。这些情境包括刷毛、在陌生环境中隔离和等待食物。每个声音文件都遵循特定的命名约定，包含猫的唯一ID、品种、性别、猫主人的唯一ID、录音场次和发声计数。此外，还有一个额外的zip文件，包含被排除的录音（非喵声）和未剪辑的连续发声序列。
