Experiences with the relocation of Northern Lapwing chicks from a flat roof in Gossau (canton of Zurich, Switzerland). – Flat roofs represent a novel breeding site for some ground-nesting birds. However, food availability on flat roofs is usually insufficient for precocial species such as the Northern Lapwing Vanellus vanellus. In some cases, a flat roof may be optimized for the species. On most roofs, however, hatchling survival rates are very low. In Gossau (canton of Zurich), we have tried to relocate the chicks that hatched on a flat roof to a nearby Lapwing colony on the ground. In 2015, the relocation was successful, several hatchlings have probably fledged. In the following year, the relocation failed. The success of a relocation operation may depend on various factors which should be taken into account during the planning phase. These factors include the proximity to a suitable releasing area, the age of the chicks, the competition within the breeding colony, the spatial habitat use of the parent birds, which will affect family reunion, and weather conditions. Furthermore, legal regulations have to be followed.
