摘要：

Disused nests containing eggs from aviary birds were used to determine the effect of human observers on the intensity of nest predation. Nest predation was significantly higher for nests visited daily than for nests visited only at the end of a typical incubation period. Care should be taken by nest observers to minimise the number of visits to nests of ground‐nesting birds. The average distance of nests from the edge of the supporting plant was greater for unsuccessful than successful nests, implying that the position of nests is an important factor affecting their survival. Predation rates on active nests of White‐fronted Chats Ephthianura albifrons visited daily over the same period were similar to those of experimental nests, suggesting that ‘artificial’ nests may be a useful tool for studying nest predation.
