Purple heron roost sites

After the breeding season, most purple herons leave the colonies to overnight in communal roosts closer to their foraging areas. Most roosts are in small to large trees in agricultural areas. In South-Holland some of these roost sites are known but most are not.

In 2012, Bureau Waardenburg together with Landschapsbeheer Zuid-Holland and Natuurmonumenten plan to gather information on all roosts in South-Holland in order to better understand the sites and numbers of purple herons in the region. This project will provide important information about habitat use away of the breeding colonies.

Habitat protection away from the colonies

We know that agricultural habitats are crucial for the purple heron both during and following the breeding season. These areas provide the purple herons with food with which to raise their young and to fatten up before their autumn migration. It is not clear however, exactly which areas are the most important for the species, which sites hold key roosts and where the purple herons from the colony at the Nieuwkoopse Plassen go. We aim to answer these questions by following the birds after they have left their colonies. This information can then be used, with cooperation with landowners, to establish protection plans and enhance the habitats.
