参观繁殖斑块可以让勘探个体收集有关当地斑块质量的信息，以便在下一年选择繁殖栖息地时做出最佳决策。许多鸟类都描述了这种探矿行为。然而，探矿者收集的信息的性质往往仍然未知。我们收集了领鹟（Ficedula albicollis）（一种小孔筑巢雀形目鸟类）的探矿行为数据，以调查探矿者是否可以收集有关其同种繁殖成功的信息，即“公共信息”。如果可以的话，他们将被期望检查同种巢穴，在公共信息可靠的时候进行勘探，并被成功的地点所吸引并在那里度过时光。同种巢穴的勘探活动很频繁。探矿者以男性为主，探矿活动与筑巢活动高峰期密切相关。在巢穴中观察到探矿者的可能性随着父母的活动而增加，通过喂食率和警惕行为来衡量，但并不取决于对检查巢穴成功与否的直接衡量（雏鸟数量和状况）或雌性特征。由于摄食率和警惕行为是雏鸟繁殖成功的预测因素，因此当发现父母的显着活动时，探矿者就会被最成功的巢所吸引。因此，探矿者可以收集有关当地同种繁殖成功的准确信息，这些信息可用于明年的繁殖斑块选择。我们讨论了对我们的结果的其他解释，以及通过实验测试探矿者是否收集公共信息的必要性。我们还讨论了育种限制对勘探的作用以及性别差异的起源。 (C) 2004 年动物行为研究协会。由爱思唯尔有限公司出版版权所有。
Visiting breeding patches can allow prospecting individuals to gather information on local patch quality to make optimal decisions about selecting a breeding habitat in the following year. This prospecting behaviour has been described in many bird species. However, the nature of the information gathered by prospectors often remains unknown. We collected data on prospecting behaviour in the collared flycatcher, Ficedula albicollis, a small hole-nesting passerine bird, to investigate whether prospectors could gather information on their conspecifics' reproductive success, that is, 'public information'. If they could, they would be expected to inspect conspecific nests, prospect at the time when public information is reliable, and be attracted to, and spend time at, successful sites. Prospecting at conspecific nests was frequent. Prospectors were mainly males, and prospecting activity closely matched the peak of nesting activity. The probability of observing a prospector at a nest increased with parental activity, measured by feeding rate and vigilance behaviour, but did not depend on direct measures of success of the inspected nest (nestling number and condition), or on female characteristics. Because feeding rate and vigilance behaviour were predictors of breeding success at fledging, prospectors were attracted to the most successful nests when cueing on conspicuous parental activity. Therefore, prospectors could gather accurate information on local conspecific reproductive success that may be used for breeding patch choice in the following year. We discuss alternative explanations for our results, and the need to test experimentally whether prospectors gather public information. We also discuss the role of breeding constraints on, and the origin of sex differences in, prospecting. (C) 2004 The Association for the Study of Animal Behaviour.
