鸟的飞行极限在哪里？据研究人员统计，成年信天翁一年飞行的距离可绕地球三圈，一只信天翁一生的飞行距离可超600万公里，相当于在地球与月球之间往返八次！这是地球上最能飞的鸟，也是世界上最大的飞鸟。

Albatrosses are big， 1）majestic birds that can be found soaring above most of the world's oceans. Most albatross habitats are in the Southern 2）Hemisphere.

信天翁是大而了不起的鸟类，人们发现它们在世界大多数海洋上飞翔。大多数信天翁栖息于南半球，只有3种信天翁居住在北太平洋。信天翁是最大的飞鸟之一，翼展在鸟类中最大，长到6.5—11英尺，而其中的一种——大信天翁的翼展是所有鸟类中最长的，达12英尺。

信天翁是所有鸟类中最善于滑翔的，能够在大风天气中停留高空数小时，而无需拍打它们极其长而狭窄的翅膀。在无风的天气中，信天翁很难保持其粗壮的身体停留在空中，所以会在水面上休息。

信天翁，就像其他的海鸟一样，喝海水。它们主要以觥鱼为食，在海洋传说和迷信中有着特殊的地位，海员曾经相当敬畏信天翁：他们认为杀死信天翁会带来坏运气。

尽管信天翁经常被赋予传奇的地位，但它们并没有逃脱来自人类间接或直接的压力。目前，在世界自然保护联盟红色名录上确认的21种信天翁中，有19种受到威胁，另外2 种濒临威胁。3种信天翁（世界自然保护联盟已确认）被列为极危物种。
