This study investigated the basal metabolic rate (BMR) in individual zebra finches as they aged in captivity. BMR is a measure of the energy consumption of organisms when they are at rest.

In captivity we could measure the same individuals repeatedly when they were 1, 3 and 5 years of age. This covered a substantial proportion of the maximum lifespan of this small bird species.

Interestingly, the results showed that BMR decreased as they aged. This is similar to what has been reported for humans, and we think that these results may contribute to the understanding of ageing patterns. Contact: Dr Børge Moe, Norwegian Institite for Nature
