Heart rate of geese increases by 96%, while body temperature rises as well
New research has discovered that firework displays can cause significant stress to wild birds.
Published in the journal Conservation Physiology, the research was led by Dr Claudia Wascher of Anglia Ruskin University (ARU) and is one of the first studies ever carried out into the effects of fireworks on wildlife.
The study involved 20 wild greylag geese (Anser anser) fitted with temporary transmitters to record their heart rate and body temperature, which are measures of physiological stress.
The research was carried out at Almsee, a lake in Upper Austria. Villages close to the lake hold New Year’s Eve celebrations, with midnight firework displays marking the new year.
The study discovered that the average heart rate of the geese increased by 96% (from 63 to 124 beats per minute) and their average body temperature increased by 3% (from 38°C to 39°C), in the first hour of 1 January (midnight to 1am).
Between 1am-2am, after the fireworks had ended, their average heart rate was still 31% above normal while the average body temperature remained 3% higher than normal. It took approximately five hours for the geese to display normal body temperatures, with average readings only returning by 5am on 1 January.
The wild geese in the study were part of a resident population at Almsee and the researchers found no evidence that age influenced their physiological response, indicating that geese do not become desensitised to fireworks over time.
