Male Reproductive Strategies And Mating Displays In The Ocellated Turkey (Meleagris Ocellata)
… These apathetic males may be exhibiting alternative reproductive strategies, or simply delaying maturation to conserve resources for future breeding attempts. In populations of the poorly studied, near-threatened Ocellated Turkey (Meleagris ocellata), males have been reported to be either …
