Yellow-billed Cuckoo

A common, but slow-moving and secretive denizen of woodlands, the Yellow-billed Cuckoo eats large quantities of hairy caterpillars. Its loud call is heard far more frequently than the bird is actually seen.

Like the Black-billed Cuckoo, the young Yellow-billed Cuckoo develops incredibly quickly. The entire period from egg laying to fledgling leaving the nest lasts only 17 days. On day six or seven after hatching, the feathers of the young burst out of their sheaths, allowing the nestling to become fully feathered in two hours. Both parents build the nest, incubate the eggs, and brood the nestlings. They incubate and brood equally during the day, but the male takes the night shift. The male brings nest material every time he comes to the nest to take his turn. The female usually takes the offering and works it into the nest.
