“…In many cases the study setup has not been ideal for studying the general quality differences in hand-reared and wild birds (Krauss et al 1987, Brittas et al 1992, Leif 1994, as wild birds are represented by a local bird population. A comparison between wild and introduced hand-reared pheasants is hence ambiguous, because the wild birds are already adapted to the conditions in the study area.…”

The quality of released individuals can have a significant impact on the success of reintroduction projects. We tested which of the following release techniques resulted in the highest survival of released grey partridges Perdix perdix in Switzerland : 1) translocation of wild adult birds, 2) release of captive parent-reared adults as family groups, and 3) fostering of captive parent-reared chicks to wild barren pairs. Wild hatched offspring (F1 birds) from our re-established breeding pairs served as the control group. We used a multi-state capture-recapture model to estimate monthly survival rates from the data based on monitoring of radio-tagged individuals and reobservation and recovery of ringed individuals. Survival tended to be highest in wild-hatched partridges of the founder population (mean ± SE; 0.90 ± 0.03), followed by that of fostered chicks (0.86 ± 0.03) and translocated adult wild birds (0.82 ± 0.06). While survival of these groups was not statistically different from each other, survival of captive-reared adults was significantly lower (0.70 ± 0.06). We discuss the implication of our results for further partridge reintroduction projects.

“…Carrol and Hollins (1999) reported that there is much emphasis on searching for superior genetic stock. Studies have shown that wild pheasants in comparison to gamefarm birds are more shy and show a higher level of fear (Majewska et al 1979;Krauss et al 1987). Therefore, only subspecies with a certain level of fear and timidity should be used (for releases to the wild) so that they can survive.…”

“…Wild-living pheasants show a much higher survival rate in the same natural habitat than those released to the wild (Anderson 1964;Waurisch 1975;Pielowski 1981;Krauss et al 1987;Hill and Robertson 1988;Brittas et al 1992;Leif 1994). In past studies, differences in the survival rates of pheasants between genetic groups are not included, although the different subspecies have different ecological demands (Schwartz and Schwartz 1951).…”

Comparative study of predator avoidance behaviour of pheasants (Phasianus colchicus) of different genetic origin

The aim of the study was to determine differences in the behaviour of chicks of three different pheasant subspecies. The timidity of the pheasant chicks was of special interest, therefore behaviour traits were analysed using an open-field test and a tonic immobility test. In total, 137 pheasant chicks were tested including the copper pheasant (Ph. c. colchicus; n=87), the green pheasant (Ph. c. versicolor; n=12) and the melanistic pheasant (Ph. c. tenebrosus; n=38). In both tests, the chicks of the versicolor group showed the highest timidity, whereas the other two groups were similar in timidity. In the open-field test, the chicks of the colchicus group showed the lowest timidity, and in the tonic immobility test, the tenebrosus group showed the lowest values. Assuming a relationship between the test results and predator avoidance behaviour, it can be concluded that the chicks of the versicolor group show the best predator avoidance behaviour. Further investigations are needed to find out whether the differences in the analysed behaviour traits result in higher survival rates after releasing to the wild.
