Why penguins are black and white ...
It’s that time of year again when a lot of our penguins are staying in their nests to look after their eggs. This breeding season occurs twice a year, usually around March/April and September/October and our Humboldt penguins will have just one mating partner. The female will lay two eggs into a burrow, and these will be incubated for around 40 days until the eggs hatch, with both parents sharing the work. After 12 weeks the chicks will fledge the burrow, and then become fully mature at two years old. Once the breeding season is over, penguins will usually enter a moult phase where they replace their current feathers with new ones. During this phase the penguins can look very scruffy and will spend less time in the water as their body will no longer be waterproof and insulating. They will also not eat anything whilst they are moulting, so they need to make sure they eat enough before the moult begins to ensure they have enough fat reserves in their body!
