Clutch size declined by 1 egg for every 14–20 elapsed days in the nesting season and the rate of decline was independent of incubation attempt (1 or 2); this result suggests that lower clutch sizes later in the nest season were not necessarily a function of re‐nesting. Male Northern Bobwhite vary considerably, but females look similar across their range. <> endobj Both males and females incubate the eggs, brood the hatchlings, and provide for the young until they reach independence at about 2 weeks old.

Abstract: We studied northern bobwhites (Colinus virginianus) in western Oklahoma, USA, during the nesting seasons of 1992–2001. Bobwhites that entered the reproduction period starting on 15 April (n = 229) accumulated 203 nesting attempts (male and female incubations), which translated to 1.7 attempts/hen for all hens that entered (n = 117) and 3.1 attempts/hen for hens that survived to 15 September (n = 65). For pooled data on bobwhites alive during 15 April‐15 September, 64 ± 6.5% of juvenile females (n = 56), 90 ± 10.0% of adult females (n = 9), 13 ± 4.1% of juveniles males (n = 68), and 41 ± 10.7% of adult males (n = 22) incubated ≥ 1 nest.

REPRODUCTIVE ECOLOGY OF NORTHERN BOBWHITE IN NORTH FLORIDA THEODORE DeVOS, 1 Tall Timbers Research Station, Tallahassee, FL 32312 BRADS. In the “Strategic Plan for Bobwhite Restoration in Florida,” overall goals and strategies to achieve those goals are outlined. Northern Bobwhites were once a common species in eastern North America, but experienced widespread, sharp declines between 1966 to 2014, up to 4% per year, resulting in a cumulative decline of 85%, according to the North American Breeding Bird Survey. Their mottled brown, black, and white feathers help this species blend in to the bushes and shrubs it lives in. The Northern bobwhite is a member of the order Galliformes, from the Latin ‘gallinaceus’, which means “of poultry.” They belong to the same order as domestic fowl, also including turkeys, grouse, pheasants, partridges and other quail. The loud “bob-white” call of this small chicken-like bird can be heard for a quarter mile in open country. Bobwhites that entered the reproduction period starting on 15 April ( n = 229) accumulated 203 nesting attempts (male and female incubations), which translated to 1.7 attempts/hen for all hens that entered ( n = 117) and 3.1 attempts/hen for hens that survived to 15 September ( n = 65). %PDF-1.7 %���� <> The northern bobwhite quail (Colinus virginianus) is an important game bird that is intensively managed for hunting recreation in the southeastern United States.

Average age at sexual or reproductive maturity (male) 1 years; Bobwhite hatchlings are able to walk about and follow their parents almost immediately following hatching. This long breeding season provides opportunities for multiple nesting attempts and contributes to the bobwhite’s high reproductive potential.
