Food pecking in the ring dove is a skilled prehensile response that is similar to, but simpler than, many other prehensile responses. Previous work has shown that this response is initially poorly executed and requires experience for its accurate direction and coordination. The response involves two components: the thrusting of the bird's head toward food, and the opening and closure of the beak around food. Here, this second component, called gape, is followed through development with a precise measurement system. Four squabs moved through a similar sequence of three gape topographies, each of which is more efficient in picking up seed, during development. The present outcome, together with other work, argues for a substantial contribution of experience with pecking to the development of food pecking. We discuss the implications of these findings for understanding the ontogeny of motor control and for understanding how experience affects behavioral development.
环鸽的食物啄取是一种熟练的抓握反应，它与许多其他抓握反应相似，但更简单。先前的研究表明，这种反应最初执行得很差，需要经验才能准确地定向和协调。该反应包括两个部分：鸟头向食物的 thrusting，以及喙围绕食物的张开和闭合。在这里，通过一个精确的测量系统对称为 gaping 的第二个部分进行了发育跟踪。在发育过程中，四只雏鸽经历了类似的三个 gaping 地形序列，每个序列在拾取种子方面都更有效。目前的结果与其他研究一起，表明啄食经验对食物啄取的发展有重大贡献。我们讨论了这些发现对于理解运动控制的个体发生以及理解经验如何影响行为发展的意义。
