Grey Heron is widely distributed throughout much of the Old World, in Europe, Africa and Asia, but absent in the boreal region and deserts(BirdLife International 2021). Migratory behaviour varies from resident to partial migrant or migratory (Voisin 1991) with a cline of increasing migration to the N and E.

Medium-sized passerine, feeds on seeds, berries, and (in summer) invertebrates, especially Lepidoptera larvae and beetles (Coleoptera); in winter quarters specializes in beechnuts Fagus sylvatica. Breeds across boreal and subarctic zones of west Palearctic, in the more open birch Betula woods, and in mixed forests of birch and conifers. Winters in Europe from S Sweden to N Morocco and from UK to Turkey and Georgia. The population trend appears to be decreasing, but not sufficiently rapid to approach the thresholds for Vulnerable. A medium distance migrant. Extent of movement is strongly dependent on food availability; local concentrations of millions of birds occur in south-central Europe.

This reedbed passerine has an extended mid-latitudes distribution across Eurasia, highly fragmented in Europe, ranging from Spain (Peiró 2013) to southern Finland. Mostly resident in the south, some short-distance movements in the north. Tightly linked to Phragmites reedbeds across its range.

An exclusively marine, medium-sized seabird, occupying rocky coastal regions on steep mainland cliffs and offshore islands (Lavers et al. 2020). Its range extends across the temperate, boreal and low-arctic waters of the N Atlantic. Patchily distributed in Europe, from NW France and the British Isles to Iceland (holding the bulk of population), N Norway, Bear Is and NW Russia (Keller et al. 2020).

Trans-Saharan migratory passerine, it breeds from W Europe to Central Siberia (avoids the boreal belt); spends the winter in wetlands across the Sahel and further S (BirdLife International 2021).

The species occurs in open and semi-open forest and woodland habitats, farmland with trees, parks and gardens in human settlements. For hunting, it requires richly structured habitat, often with some preference for access to water (Holt et al. 2020). 

Its distribution covers most of W Palearctic – the species is widespread in Europe (except for N Fennoscandia and NW Russia), the occurrence is patchier in NW Africa, Middle East and C Asia (Keller et al. 2020).

All populations are resident. However, long-distance dispersal movements are rarely recorded.

Its population trend in Europe is unknown. Evaluated as “Least Concern” (BirdLife International 2021).
