 abstract={The nests of great reed warbler (Acrocephalus arundinaceus L.) and reed warbler (A. scirpaceus Herm.) are compared to platforms supported by columns (reeds). The paper presents a model of the nest structure. Variables of this structure, such as: number of reeds supporting the nest, height of reeds, their thickness, weight of a nest with its contents etc. show statistically significant differences for each species under investigation. However, stresses occuring at the base of the construction, which result from the above variables, are similar in both species. The wind is the main hazard to the stability of the construction. It was stated, that the majority of nests are built with a big durability margin, and the ecological reasons for this phenomenon were analysed.},
