Animal heredity and variation are investigated in animal genetics, a subspecialty of veterinary medicine. It is based on general genetic concepts and principles and primarily employs the twin, population, and hybrid, cytological, mathematical-statistical, and ontogenetic approaches of general genetics. Animals inherit their traits primarily independently since they have a vast number of chromosomes. Hybrid analysis, which identifies the nature of the inheritance of several morphological, physiological, and biochemical traits many of which typically depend only on one of multiple pairs of genes, is the main technique for examining the inheritance of characters. Tawny owls are extensively distributed as birds that live in southern Turkey and northern Finland, according to the Red List of IUCN endangered species. The Korean Peninsula, however, was not included. Animals actively defend their territories against other members of their own species. The territory of an animal is the area in which all behavioural behaviours occur. Animals must be tracked using tools like radio transmitters for home range research. Can be used to record behavioural information like migration paths and time spent in particular places. Follow-up surveys on tawny owls revealed information about population dispersal brought on by subsequent juvenile migration in the second half of the breeding season. The range of tawny owls, which are nocturnal raptors, extends from Scandinavia to East Asia. Although it can also be found in small gardens, parks, and urban areas, this plant favours a rainforest environment. If a tawny owl chooses its habitat as a young animal, it stays there with the local birds. Particularly during nonbreeding seasons, males are less likely to leave the area and stay in a favourable habitat, while females may do so after breeding. Tawny owls, on the other hand, have short wings at high a altitude, which give them mobility in the forest but limits their ability to fly over great distances. Although females tend to be slightly larger than males, there isn't much overt sexual dimorphism between the sexes, making visual sex determination challenging. Even so, a distinct horn sound can be used for audio identification. In the United Kingdom, a lengthy nest box survey was conducted to track the steady breeding of about 20,000 tawny owl pairs away from Asia. Both males and females are capable of reproducing by the age of one, but pairs usually guard their habitat and put off mating until the age of three, when there is enough food. In South Korea, the tawny owl is a common bird and a protected species. In South Korea, 37 areas were identified as tawny owl habitats between 2001 and 2014. The species, which is already listed on the Korean Red List as Grade II Endangered Wildlife by the Ministry of the Environment due to a steadily declining population, was recently designated as Vulnerable. Studies that have already been done on tawny owls in South Korea have either looked at bird sounds or reviewed the literature to determine the distribution of mating pairs and the timing of reproduction by region. There has only been one study on the habitats and migration of tawny owls in South Korea during the nesting season. It is vital to look into the tawny owl's breeding season minimum habitat and suggest suitable potential habitat in order to protect the species in South Korea. In order to gather information on habitat utilisation and home range, we conducted case studies of breeding pairs and followed them throughout the mating season. Such knowledge is crucial for the tawny owl's survival. Our findings could serve as a case study for important efforts to estimate the geographic range of tawny owls. During the mating seasons of 2016 and 2017, the tawny owl's home range in the area of Andong, Gyeongsangbuk-do, was examined. On the southern slopes of the Taibak Mountains, the study location was situated in a low-elevation forest area. The average annual rainfall in this region was 1018.5 mm, and there were roughly 103 days with rain.
