笼子大小被广泛认为是圈养动物福利的一个重要决定因素，但相比之下，笼子形状受到的关注要少得多。对飞禽的饲养建议指出，笼子的形状应该是长的，因为这允许更大的飞行潜力。然而，到目前为止，还没有研究调查笼形对圈养飞禽的行为或福利的影响。我们测量笼大小和形状的影响,条件和行为的俘虏野生欧洲椋鸟(Sturnus寻常的)使用2 x 3的阶乘设计,1周在笼子里的鸟被单独安置两个卷(介质为0.3米(3)或大型1米(3)),以及三种形状(长与宽高比(即长度/高度)的3.43),标准的长宽比1.72或高的长宽比0.86)。我们发现笼的大小和笼的大小和形状的相互作用对鸟类的行为和状态的影响。在解释我们的研究结果对福利的影响时，我们把重点放在了通过翻跟头的发生率来衡量的刻板行为上，以及一个新的统计数据，该统计数据量化了鸟类在笼子里位置的顺序依赖性。在大笼子和中长笼子中记录的刻板行为最低。在中等笼中，笼形比在大笼中更能决定定型行为的数量。我们的发现支持了把椋鸟关在长形笼子里的建议。(C) 2008 Elsevier B.V.版权所有
Cage size is widely recognised as an important determinant of captive animal welfare, but in contrast, cage shape has received far less attention. Husbandry recommendations for flying birds state that cages should be long in shape because this allows greater potential for flight. However, so far no studies have investigated the impact of cage shape on the behaviour or welfare of captive flying birds. We measured the effects of cage size and shape on the condition and behaviour of captive wild-caught European starlings (Sturnus vulgaris) using a 2 x 3 factorial design in which birds were individually housed for 1 week in cages of one of two volumes (either medium at 0.3 m(3) or large at 1 m(3)), and one of three shapes (long with an aspect ratio (i.e. length/height) of 3.43), standard with an aspect ratio of 1.72 or tall with an aspect ratio of 0.86). We found effects of cage size and the interaction of cage size and shape on the behaviour and condition of birds. In interpreting the welfare implications of our results we focused on stereotypic behaviour as measured by incidence of somersaulting and a novel statistic that quantifies sequential dependencies in the birds' locations within the cage. The lowest measures of stereotypic behaviour were recorded in the large cages and the medium long cage. Cage shape was more important in determining the quantity of stereotypic behaviour in the medium cages than the large cages. Our findings support the recommendation that starlings be housed in long-shaped cages. (C) 2008 Elsevier B.V. All rights reserved.
