Abstract

Seabirds have long lives, reproduce slowly and usually do not attempt to relay within the same breeding season after nest failure. In Sandwich Terns Thalasseus sandvicensis, renesting has never been documented despite the large number of studies on their breeding ecology and recorded prospecting behaviour after nest failure. In 2020, we observed how three GPS-tagged Sandwich Terns moved 115 km after nest failure for a second breeding attempt. One of these birds hatched a chick from the second clutch successfully. We hypothesize that synchronous breeding usually prevents Sandwich Terns from trying again after nest failure and that the relays observed in 2020 were facilitated by the unusual situation of a successful breeding colony that started three weeks later than all other colonies in the Netherlands.
三明治燕鸥在不同群体中的二次繁殖尝试:群体间繁殖异步促进?
海鸟寿命长,繁殖缓慢,在筑巢失败后,通常不会在同一繁殖季节内尝试转产。尽管对三明治燕鸥的繁殖生态学进行了大量研究,并记录了其筑巢失败后的找巢行为,但从未有过对其进行抵抗的记录。2020年,我们观察到三只带gps标签的三明治燕鸥在筑巢失败后移动了115公里,进行了第二次繁殖尝试。其中一只成功地从第二窝孵出了一只小鸡。我们假设,同步繁殖通常会阻止三明治燕鸥在筑巢失败后再次尝试,而2020年观察到的接力是由于一个成功的繁殖群体比荷兰所有其他群体晚三周开始的不寻常情况促成的。

期刊介绍: Ardea is the scientific journal of the Netherlands Ornithologists'' Union, and is published since 1912. The journal welcomes manuscripts reporting significant new findings in ornithology, in particular those covering the ecology, life history, and evolution of birds, and including sound descriptive work. Ardea publishes Original research papers, Short notes and Book reviews. In addition to the regular three issues per year, Ardea publishes specials that contain conference or workshop proceedings (produced on request).
