Four out of six nestlings of a Sparrowhawk were found on the ground in a tiny woodlot on an industrial estate, where they were being fed by the parents, after the nest had presumaly been destroyed by high winds. An artificial nest was erected in the nesting tree using material collected at the industrial site, and the nestlings were apparently reared successfully (at least two seen as fledgling). The original nest was built in a Norway spruce on an industrial depot (65 x 100 m) in the village of Didam, eastern Netherlands.
