摘要

不同鸟类亲代抚育的时间差别很大。凤头燕鸥在雏鸟羽翼未丰后的几个月里，至少会偶尔给雏鸟喂食。我们记录了一只三明治燕鸥幼崽在纳米比亚南部的越冬地被怀疑是它的父母喂养，距离最近的繁殖地超过1万公里，而且是在羽翼初生6个多月后。

Sandwich Tern Feeds Juvenile on Wintering Grounds in Southern Namibia

The duration of parental care varies widely among bird species. The crested terns Thalasseus spp. continue to feed their chicks at least sporadically for several months after fledgling. We recorded provisioning of a juvenile Sandwich Tern T. sandvicensis by its suspected parent at the wintering grounds in southern Namibia, more than 10,000 km away from the nearest breeding site and more than six months after fledging.
