Birds losing feathers for summer
Wednesday, 11 Jul 2012
NEW Zoo director Neil Anderson says that happens once a year, usually at the end of July or beginning of August. The new features grow in and push the old ones out.
Before they molt, penguins will eat a lot. The birds almost double their weight, and their wings swell up.
Molting is a stressful time for penguins. They will stop eating and don't swim. Molting usually takes about two weeks.
