A Really Old Bird with Chicks


How old can a bird live in the wild? And how long can they breed successfully. Records are sparse of course. A Laysan albatross named Wisdom, is at least 60 years old and was spotted in February 2011 raising a chick at the Midway Atoll National Wildlife Refuge in the Pacific Islands. The bird has sported and worn out 5 bird bands since she was first banded by U.S. Geological Survey scientist Chandler Robbins in 1956 as she incubated an egg. Robbins estimated Wisdom to be at least 5 years old then since this is the earliest age at which these birds breed, though they more typically breed at 8 or 9 after an involved courtship lasting several years. This means, of course, that Wisdom is more likely to be in her early sixties. While no bander goes out to study the maximum lifespan of a species as the only reason for their banding, every bander can contribute to this information. The information on life span is collected every time a banded bird is reported. The maximum longevity record cannot be longer than the time span that researchers have been studying that species, and the lifespan of the bands used on birds was shorter than the lifespan of the birds for some species. Most banders that are working on species with long lifespans are using a harder metal band that will last as long as the bird lives.
