Roosting times of starlings in Schleswig-Holstein (Northern Germany) are closely correlated with sunrise and sunset. A close examination reveals that in autumn the activity time is shorter than under identical photoperiods in spring. Similar results were published by HAARHAUS, who studied starlings during their nesting time.
德国北部石勒苏益格-荷尔斯泰因州椋鸟的栖息时间与日出和日落密切相关。仔细观察发现,秋季椋鸟的活动时间比春季相同光周期下的活动时间短。HAARHAUS在研究椋鸟筑巢期时也发表了类似的结果。
