The repopulations carried out with captive raised red-legged partridges don’t seem to conduct to satisfactory results. Currently, the partridges present to the free state in different Tuscany areas (obtained from captivity raised animals) are not yet able to reconstitute self sustaining wild populations. The presence of hybrids with non indigenous partridges (E.G.A. chukar) and the genetic/behavioural alterations, due to the traditional breeding, are presumably the principal causes of the insufficient quality of the reintroduced animals. For these reason we wanted to test the reproduction ability of the genetically pure red-legged partridges in controlled aviaries with the aim to produce partridges more fitted for wildlife release. 14 couples of red partridges, certified genetically not hybridized with A. chukar by theNational Institute for Wild Fauna, were used for the test. Only 6 couples brooded the laid eggs and only 3 couples of them completed the brooding, with the birth of 17 partridges in total. The study therefore has underlined the necessity to use the direct brooding for the selection of the reproducers of the game farms, with the aim to improve the natural reproductive ability of the captive raised animals.
