India, Jan. 23 -- Antarctic penguins are breeding earlier at record speeds as local temperatures rise

Some colonies have advanced breeding by up to 24 days, scientists say

Researchers warn the shift could increase competition for food and nesting space

Warming in Antarctica driven by climate change is forcing penguins in the region to breed significantly earlier than before, with some species advancing their breeding season by up to 24 days, scientists have found.

A new study published in the Journal of Animal Ecology found that penguin colonies across parts of Antarctica are experiencing rapid local warming, prompting record-breaking shifts in breeding behaviour.

Data from camera-mounted temperature loggers showed that penguin colon...
