World’s Oldest Wild Bird Is a Mother Again
The oldest known wild bird in the world has become a mother again.
American wildlife officials said the egg of a Laysan albatross named Wisdom opened earlier this month. It happened at the Midway Atoll National Wildlife Refuge, northwest of Hawaii.
Wisdom is at least 68 years old and has raised at least 31 baby birds, or chicks. Wisdom was first identified as an adult in 1956.
Wisdom and her mate, Akeakamai, have been returning to the refuge to lay and hatch eggs since 2006. Laysan albatrosses mate for life. They lay one egg a year.
Beth Flint is a biologist with the U.S. Fish and Wildlife Service. She told the Honolulu Advertiser newspaper, "Wisdom is rewriting history about our understanding of survivorship, how long birds live, and how often they breed."
Midway Atoll National Wildlife Refuge is home to about 3 million seabirds, including around 1 million Laysen albatrosses.
The birds can also be found near Mexico and Japan. The albatrosses spend most of their lives flying over the ocean. They feed on squid and fish eggs. They can fly as far as 2,500 kilometers away from home to look for food. Biologists say they always return to the places of their birth to lay eggs and raise their young.
After an egg is laid, albatrosses take turns sitting on it to keep it warm. This lasts for about seven months. It is a process called incubating.
The young chicks fly out to sea about five months after they hatch.
Kelly Goodale is a biologist at the refuge. She says Midway Atoll contains "countless generations and families of albatrosses."
She says that when Wisdom returns to the refuge, she is "surrounded by what were once her chicks and potentially their chicks."

美国野生动物官员说，一只名叫“智慧（Wisdom）”的黑背信天翁下的蛋于本月初孵化 。事情发生在夏威夷西北部的中途岛国家野生动物保护区 。
至少68岁的智慧抚育了至少31只雏鸟 。1956年，智慧首次被确认已成年 。
智慧和其伴侣“Akeakamai”自2006年开始返回保护区产卵 。黑背信天翁一生只与一名伴侣交配 。每年只产一枚蛋 。
贝丝·弗林特（Beth Flint）是美国鱼类和野生动物组织的生物学家 。她告诉《火奴鲁鲁广告人报》，“智慧正在颠覆我们对生存、鸟类寿命和繁殖率的认知 。”
在墨西哥和日本附近也能发现这种鸟 。信天翁一生中的大部分时间都在海上飞行 。它们以鱿鱼和鱼卵为食 。它们可以飞往离巢2500公里的地方寻找食物 。生物学家指出，这类鸟总是返回出生的地方产卵和养育后代 。
产下蛋后，信天翁会轮流坐在蛋上保持温度 。这一过程大约要持续7个月 。该过程名为孵化 。
凯利·古德勒（Kelly Goodale）是该保护区的生物学家 。她说，“无数代信天翁和信天翁家族在中途岛环礁野生保护区繁衍生息” 。
