Agreement on the Conservation of Albatrosses and Petrels

A Buller’s Albatross banded by pioneer researcher Lance Richdale reached an estimated age of 57 years

Recent news items posted to this web site have reported on banded albatrosses that have lived for many decades, with two individuals reaching more than 60 years of age (click here).

New Zealand albatross pioneer Lancelot Richdale (click here for a review of his biography) visited The Snares Islands to work with Buller’s Albatrosses Thalassarche bulleri in early 1948, when he then banded 161 breeding birds. One of the birds he banded as a breeding female (G98) was rebanded as M-14721 in 1969 and was last recorded incubating in the same colony in March 1992 and again in March 1993 by Paul Sagar of the National Institute of Water & Atmospheric Research.

According to Paul “[w]ith a median age of 1st breeding of 12 years this bird was likely to be at least 57 years old when last seen.” The bird was photographed in 1948 by Lance Richdale and again in 1993 by Paul Sagar. These two photographs may be compared on page 128 of Neville Peat’s biography of Richdale. No signs of aging discernible!
