Penguins are probably juvenile Magellan penguins. We wee told there was only one Humboldt penguin seen where we were. The Humboldt penguins have black on their face, white below and a single black stripe on their chests. The mature Magellan penguins have black faces, white below, a black band that goes around to the black feathers on the back, then white and a second black band.
