Character Abstract
Identification Comments:
Subspecies Comments:
Food Habits:Cuckoos eat a wide variety of prey items. These are primarily large arthropods such as cicadas, katydids, grasshoppers, and caterpillars, but may also include small lizards and spiders (Halterman et al. 2011).Gleans food from branches or foliage, or sallies from a perch to catch prey on the wing (Ehrlich et al. 1992).
Phenology Comments:
Reproduction Comments:Breeding often coincides with the appearance of massive numbers of cicadas, caterpillars, or other large insects (Ehrlich et al. 1992). Clutch size is one to five (commonly two to three), largest when prey is abundant. Clutch sizes greater than six attributable to more than one female laying in nest (Hughes 1999). Incubation lasts 9-11, shared by male and female during day; male incubates at night (Hamilton and Hamilton 1965, Potter 1980, Potter 1981). Young are tended by both parents, climb in branches at seven-nine days.
Migration Mobility:Winters primarily in South America, east of the Andes. Relatively late spring migrant, arriving on breedign grounds starting mid- to late May, 4-8 weeks later than eastern cuckoos occurring at the same latitude. Considerable numbers not present until early to mid-Jun, and transients continue to be recorded late June to mid July. In fall, western cuckoos depart 2-3 week earlier than eastern cuckoos. Departures begin in late Aug with most birds gone by mid Sep. Stragglers occur from late Sep to Nov, but very rarely after early Oct. Migrates sometimes in small, silent groups, but also observed in large numbers during migration in Central and South America. Migrates predominately at night.
Habitat Comments:BREEDING: Riparian obligate species which requires dense cottonwood-willow forested tracts. In some areas, birds required 17+ ha (42 acres), including a minimum of 3+ ha (7.5) of closed-canopy, broad-leaved forest. Nests are placed in willows, but cottonwoods are used extensively for foraging.
Ecology comments:Territory size averages 20-24 hectares (S. Laymon, in Riparian Habitat Joint Venture 2000).  Major predators include falcons (adults), jays, grackles, snakes, and some small mammals (eggs and nestlings).
