Modern game birds rearing methods use mechanical incubators to hatch eggs and artificial brooders to intensively rear birds. However, the lack of parental care can have consequences on behavior and welfare of these birds affecting also survival after their release in the wild. In this study, we compared the response of 4-week-old young pheasants (brooded by a foster mother hen and artificially brooded) to two behavioral tests (duration of tonic immobility and response to aerial predator). Tonic immobility was significantly different between the two groups of birds indicating a higher level of fear in artificially brooded pheasants compared to brooded pheasants. Pheasants brooded by a foster hen showed a stronger response to aerial predator compared to artificially brooded pheasants. The foster hen seems to have a positive effect on pheasant chicks’ behavior reducing the fear and improving the ability to perceive threats.

有无父母形象饲养的幼雉的恐惧和行为
现代野禽饲养方法使用机械孵化器孵化鸡蛋和人工育雏器来集中饲养鸟类。然而,缺乏父母照顾会对这些鸟类的行为和福利产生影响,也会影响它们在野外释放后的生存。在这项研究中,我们比较了 4 周大的幼雉(由养母鸡育雏和人工育雏)对两种行为测试(强直不动的持续时间和对空中捕食者的反应)的反应。两组鸟类之间的强直不动性显着不同,表明与人工育雏野鸡相比,人工育雏野鸡的恐惧程度更高。与人工育雏的野鸡相比,由寄养母鸡育雏的野鸡对空中捕食者表现出更强的反应。
