A Culture-Based Study of Micromycetes Isolated from the Urban Nests of Grey Heron (Ardea cinerea) in SW Poland [PDF]

Animals, 2022
There are many positive relationships between micromycetes and birds: They can spread fungal spores, and fungi facilitate cavity woodpecker excavation by preparing and modifying excavation sites.

Foraging Habitat Availability and the Non-Fish Diet Composition of the Grey Heron (Ardea cinerea) at Two Spatial Scales [PDF]

Animals
Habitat structure on foraging ground is one of the crucial factors determining diet diversity in colonially breeding avian predators. Quantifying the habitat and diet composition at different spatial scales (regional and local inter-colonial) can help ...

Comparative chromosome maps between the stone curlew and three ciconiiform species (the grey heron, little egret and crested ibis) [PDF]

BMC Ecology and Evolution, 2022
Background Previous cytogenetic studies show that the karyotypes of species in Ciconiiformes vary considerably, from 2n = 52 to 78. Their karyotypes include different numbers of small to minute bi-armed chromosomes that have evolved probably by fusions ...

Cadaveric Study of the Juvenile Grey Heron's (Ardea cinerea) Nasal Cavity and Associated Structures Through Computed Tomography and Anatomical Sections [PDF]

Veterinary Medicine and Science
Background The grey heron (Ardea cinerea) is a large wading bird whose cranial anatomy reflects its piscivorous habits and aquatic lifestyle. The nasal cavity plays a key role in respiratory function and represents an important structure in the diagnosis

Individual year-round movement patterns of the GPS-tracked Grey Herons (Ardea cinerea) in Central Europe: a multi-year case study [PDF]

PeerJ
Background The year-round migratory behaviour of Grey Herons (Ardea cinerea) breeding in Central Europe is recognized; however, individual consistency in their movement patterns remains poorly known.

Characterization and Genetic Evolution of H6N2 Subtype AIV Isolates from Aquatic Birds [PDF]

Microorganisms
Birds serve as the primary natural reservoirs for avian influenza viruses (AIVs), harboring nearly all known AIV subtypes. The seasonal migratory movements of wild birds play a significant role in the transmission and dissemination of AIVs.

Colony Development and Density-Dependent Processes in Breeding Grey Herons [PDF]

International Journal of Zoology, 2013
The density-dependent processes that limit the colony size of colonially breeding birds such as herons and egrets remain unclear, because it is difficult to monitor colonies from the first year of their establishment, and the most previous studies have ...

Unusual breeding of the Grey Heron (Ardea cinerea) and Crested Tit (Lophophanes cristatus) in urban environment [PDF]

Tichodroma, 2021
Urbanization changes natural environments by transforming the landscape and reducing local biodiversity. However, some urban areas with heterogenous habitats can represent a supplementary breeding environment for non-urban birds.

Soil conditions under great cormorant and grey heron colonies in a wetland: Effect on soil nematode abundance and trophic structure [PDF]

Journal of Water and Land Development, 2023
This study aimed to investigate how great cormorants and grey herons affect the density and trophic diversity of soil nematodes under breeding colonies located in Stawy Raszyńskie Nature Reserve (central Poland).

Changes in rice cultivation affect population trends of herons and egrets in Italy

Global Ecology and Conservation, 2022
The breeding populations of colonial herons, egrets and allied waterbirds in Northwestern Italy increased since 1972, when a long-term monitoring was initiated, up to the end of the 20° century.
