Labels:text | screenshot OCR: BIRDS' EGGS Guira Cuckoo Egg U INLIKE ITS brood parasite relatives, the South American guira cuckoo looks after its own eggs and young. The sky- blue eggs are laid in communal nests, and a group of the birds cooperate to incubate the eggs and raise the chicks. LACY WHITE OVERLAY A chalky substance decorates the egg's surface; this can rub off or dry hard EGG SIZE Although the 11/2-inch-long (4-cm-long) egg seems small, it is large compared to the bird's 14-inch ROUND SHAPE (36-cm) body.
