In years when food is scarce, Antarctic's Adelie penguin chicks are rarely fed and skuas are constantly on the look-out for weakened chicks. Repeated harrying from above sends panic through the colony. Many adults are forced to regurgitate their food and the skuas eat the krill that the adults have already eaten. Small chicks that stray from the nest are quickly attacked. There is a constant battle between penguins and skuas.
