Both parents also feed the chicks. The chicks begin to leave the nest after 7 to 9 days. They begin to fly when they are about 21 days old. The male parent usually takes care of the first chick that fledges, and the female parent takes care of the rest of the chicks Ehrlich et al.
We do not know when yellow-billed cuckoo chicks become independent from their parents. Most yellow-billed cuckoos begin breeding when they are 1 year old. Some yellow-billed cuckoos may parasitize other birds by laying eggs in the nest of other parents.
They may lay eggs in the nest of other yellow-billed cuckoos, or in the nests of other bird species, including black-billed cuckoos , American robins , gray catbirds and wood thrushes. Male and female yellow-billed cuckoo parents incubate the eggs, brood and feed the chicks and protect the nest from predators. They also keep the nest clean by removing the fecal sacs from the chicks.
After chicks have left the nest, the parents keep feeding them until they are able to hunt for themselves. Yellow-billed cuckoos can live to be at least 4 years old in the wild. Yellow-billed cuckoos are solitary or live in pairs during the breeding season. They may be territorial. Yellow-billed cuckoos are migratory. They migrate at night in small groups or large flocks. Yellow-billed cuckoos are generally active during the day diurnal.
Yellow-billed cuckoos use calls to communicate. They are usually silent birds during the winter and migration. However, during the breeding season, they call often to communicate with their mate and their chicks. These birds are able to make at least 6 sounds, which they use to communicate many different things. Yellow-billed cuckoos primarily eat large insects including caterpillars order Lepidoptera , katydids , cicadas family Cicadidae , grasshoppers and crickets order Orthoptera. They also occasionally eat bird eggs, snails, small vertebrates such as frogs Order Anura and lizards suborder Sauria and some fruits and seeds.
Parents feed their chicks regurgitated insects Ehrlich et al. Adult yellow-billed cuckoos are killed by raptors, including Aplomado falcons Falco femoralis and red-shouldered hawks Buteo lineatus.
They have also been eaten by a tiger shark Galeocerdo cuvier. Nestlings and eggs are eaten by snakes such as the black racer Coluber constrictor , small mammals such as eastern chipmunks Tamias striatus , and birds such as blue jays Cyanocitta cristata and common grackles Quiscalus quiscula.
When a predator is nearby, yellow-billed cuckoos hide themselves among vegetation and stand very still. Polka Dots.
