Scientists say warmer temperatures in Antarctica are changing when penguins have babies. A new study shows that some penguins now start breeding earlier than before. This happens because ice melts sooner and food appears at a different time. Young penguins need enough food to grow, so timing is very important. When food comes too early or too late, chicks may not survive.

Researchers used cameras to watch penguins at many nesting places. They saw that gentoo penguins can adapt more easily because they eat different foods. Other penguins depend on specific food, so they face more risk. Scientists will continue to study these changes to better protect penguin populations in the future.
