Washington: A new study has revealed that personalities of the Penguins or birds help them to cope with the climate change.
As the global climate continues to change, the ability of many animal species to adapt has always been put to the test. Bird populations might be at particular risk.
According to the Audubon Society, nearly half of all North American bird species are severely threatened by shifts in climate. The threat reaches beyond North America and could have similar effects on global bird populations.
John Cockrem of the Institute of Veterinary, Animal and Biomedial Sciences at Massey University in New Zealand suggested that a bird's individual personality might be among the factors that could improve its chances of successfully coping with environmental stressors. The researcher studied differences in the level of the stress hormone corticosterone that native little penguins (Eudyptula minor) secreted when exposed to stressful stimulus.
