Environmental impacts on wetland birds: long-term monitoring programmes in the Camargue, France.
2010
10 pages; International audience; Wetlands in the Mediterranean area have become a rare habitat due to human impact. To model the ecology and breeding biology of birds depending on that habitat, we describe long-term studies on two wetland birds (Little Egret Egretta garzetta and Greater Flamingo Phoenicopterus (ruber) roseus) in the Camargue, France. The hydrological conditions in natural Mediterranean wetlands depend largely on the pattern of rainfall (winter) and evapotranspiration (summer), but have been substantially altered by human activities. In natural conditions, these wetlands are very diverse and therefore sustain a high diversity of breeding birds. At the same time their unpred…

Little Egret Egretta garzetta (Linnaeus, 1766) ( Pelecaniformes Ardeidae) and Eurasian crag martin Ptyonoprogne rupestris (Scopoli, 1769) (Passerifor…
2021
For the first time, the nesting of Eurasian crag martin Ptyonoprogne rupestris (Scopoli, 1769) (Passeriformes Hirundinidae) and Little egret Egretta garzetta (Linnaeus, 1766) (Pelecaniformes Ardeidae) in the Aegadian Islands (W-Sicily, Italy) is reported. Of particular interest is the nesting of the Little egret on the island of Maraone resulting in the first report for Sicily of a heronry on a marine island. Although this nesting environment has already been established in Sardinia, it should be emphasized that until now the establishment of a heronry has never been detected on an islet so far from the mainland.
The component helminth community in six sympatric species of Ardeidae.
2005
We studied the helminth communities in 6 sympatric species of Ardeidae (Ixobrychus minutus (Linnaeus, 1766), Nycticorax nycticorax (Linnaeus, 1758), Bubulcus ibis (Linnaeus, 1758), Egretta garzetta (Linnaeus, 1766), Ardea cinerea (Linnaeus, 1758), and Ardea purpurea (Linnaeus, 1766)) from "La Albufera de Valencia," Spain. The survey revealed 13 species of helminth parasites: 5 digeneans, 2 cestodes, and 6 nematodes. The component helminth communities of the Ardeidae examined are depauperate and conform to the pattern typically found in isolationist communities, probably because of their high trophic dependence on a few prey species. Evenness was positively correlated with richness and abund…
New colony of little egrets egretta garzetta at trapani saltpans

Breeding on man made structures has never been cited in literature for this species. First records of breeding in windmill in the saltpans of Trapani are here reported.
Herons of French Polynesia. Threats, status and conservation.
2018
8 pages; International audience; In French Polynesia, only three Ardeidae are present: Cattle Egret (Bubulcus ibis), Tahiti Striated Heron (Butorides striata patruelis) and Eastern Reef-Heron (Egretta sacra), and the last two breed there. The Eastern Reef-Heron is widespread in the Pacific range and its conservation status is least concern. However, the status of the Tahiti Striated Heron is critically endangered on the International Union for the Conservation of Nature Red List. In 2009, only 70 birds were estimated living in Tahiti and thus the entire French Polynesia. Threats are mainly due to the restricted distribution of breeding habitat and habitat destruction. The Tahiti Striated He…
