Abstrakt:	Background: Assisted reproduction techniques in birds have contributed to many species' conservation and sustainable use. One of these techniques is semen cryopreservation, which is possible following the discovery of suitable cryoprotectants. Aims: This study aimed to characterize the fresh and post-thaw ejaculates of different species of birds of prey. Methods: The following species were included in the study: red-tailed hawk ( Buteo jamaicensis ) n=3, golden eagle ( Aquila chrysaetos ) n=3, and Harris's hawk ( Parabuteo unicinctus ) n=3. Twenty-five ejaculates were obtained for each species. The percentage of spermatozoa motility, viability, and morphology were evaluated. Results: Evident differences were observed among the ejaculates of the three species, particularly in sperm length and between the fresh and post-thaw parameters of the same species in which the motility reduced to approximately 40% after thawing. It was demonstrated that sperm cryopreservation of the studied species was possible using the same freezing protocol. Conclusion: This study showed that sperm characteristics could influence the parameters obtained during their in vitro conservation, both in the fresh and post-thaw states. Competing Interests: All authors declare that there is no conflict of interest of any kind.
