The diet of the grey heron (Ardea cinerea) was investigated in three colonies in northern Poland (Mosty, Kiersity and Kąty Rybackie) varying in size, habitat type and composition of feeding areas used by birds. The diet was assessed during the breeding season on the base of pellets and regurgitated food. Pellets from all studied colonies consisted mainly of mammal hair (almost 100% of samples), bone remains (20–24%) and invertebrate remains (26–51%, mainly water beetle, Dytiscus marginalis… Expand

Seasonal Diet of the Grey Heron Ardea cinerea on an Oceanic Island (Tenerife, Canary Islands): Indirect Interaction with Wild Seed Plants
TLDR
The results indicate that Grey Heron diet on islands varies in comparison with continental zones, including an important number of invertebrates and reptiles, including the main invertebrate group, Aeshnidae larvae (Odonata). Expand
Cocoi Heron (Ardea cocoi) Connects Estuarine, Coastal, Limnetic and Terrestrial Environments: an Assessment Based on Conventional Dietary and Stable Isotope Analysis
TLDR
Complementary approaches used in the current study demonstrate that widely distributed, large-sized Ardea herons and other waterbirds are important for the connectivity of terrestrial and a range of aquatic environments. Expand
The response of Grey Herons Ardea cinerea to changes in prey abundance
TLDR
Diet composition suggests that Grey Herons in 2008–09 exploited more diverse foraging areas (dry habitats, woods, garden ponds) than in 2000–02, and adapted to the lower availability of Round Gobies by prey switching to other available fish. Expand
Feeding Ecology of Cocoi Heron (Ardea Cocoi) in the Flood Valley of the Paraná River
The feeding ecology of Ardea cocoi were analysed based on 29 herons captured on the Carabajal island (Santa Fe, 31°39'S, 60°42'W), determining the minimum sample, index of relative importance (IRI),Expand
The role of the southern water vole Arvicola sapidus in the diet of predators: a review
TLDR
The results obtained may be useful in the planning of measures for the conservation of the southern water vole, such as translocations or reintroductions, and in the design of strategies to reduce predatory pressure with the aim of promoting the success of these programmes. Expand
Stress or help, how does the grey heron Ardea cinerea L. modify the vegetation structure of the forest floor?
TLDR
Examining the influence of a grey heron breeding colony on the soil properties and functional composition of the herb layer in two different forest communities found small-seeded, light demanding eutrophic species showed a tendency to be more abundant under the nests in both forest types. Expand
The first analysis of heavy metals in the Grey Heron Ardea cinerea feathers from the Croatian colonies
This study represents the first analysis of heavy metals: lead and cadmium, as well as two metalloids: arsenic and selenium, in the feathers of Grey Herons breeding in Croatia. The Grey Heron wasExpand
Trace elements in eggshells of the Grey Heron (Ardea cinerea) from the colony in the Roztocze Hills (South East Poland)
Concentrations of 14 trace elements (Sr, B, Al, Zn, Cu, Li, Se, Mn, Cr, As, Ni, Pb, V, Cd) in eggshells of the Grey Heron Ardea cinerea collected from the colony located in the Roztocze Hills (EastExpand
Parasitic helminths in grey heron (Ardea cinerea) chicks
TLDR
It is demonstrated that grey heron chicks are infected with parasites very early in life, which may adversely impact their health, and the presence of adult C. rudolphii nematodes indicates a transfer of parasites from adult birds to chicks during feeding. Expand
Determinants of the re-occupation and size of Grey Heron Ardea cinerea breeding colonies in northern Poland
TLDR
The importance of wetland habitat features to colony re-occupation, its size and changes in size was revealed, and only models with an area of water bodies and a number of pastures were significant, suggesting the important influence of other non-habitat factors on colony re -occupation. Expand

Food intake, feeding behaviour and stock losses of cormorants, Phalacrocorax carbo, and grey herons, Ardea cinerea, at a fish farm in Arcachon Bay (Southwest France) during breeding and non-breeding season
TLDR
Adult cormorants and herons were more successful at feeding than first-years and although younger birds spent more time feeding and their biomass intake rates remained lower than those of adults birds, this imposed a significant economic loss due to low productivity of the fish farm. Expand
Exploitation by the Grey Heron of Fish Regurgitated by Cormorants
TLDR
Extra food available in the colony could be responsible for high breeding success of the herons in the mixed colony at Kąty Rybackie and was an alternative or supplementary food for adult birds during a period of bad weather. Expand
Analysis of pellets of the Grey heron, Ardea cinerea, from colonies in Belgium
TLDR
It is believed that most invertebrates, even the smallest ones, were actively taken by the herons, and the shape of a pellet seemed to be dependent upon the (moisture?) conditions during its formation. Expand
Factors affecting the breeding success of the grey heron (Ardea cinerea) in northern Poland
TLDR
In the studied colonies, the number of feeding visits was the most important factor affecting breeding success and chick mortality significantly decreased with increasing numbers of feeding visit per nest. Expand
The foraging ecology and feeding behaviour of the grey heron (Ardea cinerea) in the Camargue, S. France
TLDR
Foraging patterns of breeding Grey Herons were studied in the Camargue and an experiment on prey selection provided evidence that chicks could select between two prey types which differed only in the irrelative profitability. Expand
The response of a Grey Heron Ardea cinerea breeding colony to rapid change in prey species
TLDR
The fish community of Loch Lomond has changed rapidly in recent years following introductions of 5 new species of fish, and it would appear that this diet shift was not the result of a lack of available Roach, but was a functional shift in prey choice by herons to a more abundant, more easi...

Regurgitations from nestling Grey Herons Ardea cinerea at Loch Leven, Scotland, April-July 1981–83, contained mainly three types of prey:perch, brown trout and ducklings. The diet varied markedlyExpand
Grey heron, Ardea cinerea L., predation at cage fish farms in Argyll, western Scotland
TLDR
Adult herons were more successful at feeding than first-years and although younger birds spent more time feeding their intake rates remained lower than those of adults in terms of their total time at the farm. Expand

TLDR
The round goby, which is well suited for ecological expansion, has great potential to dominate the majority of the coastal zone of the Baltic Sea. Expand
