birds

The current knowledge about avifauna of resurgences area can be considered good and the most characteristic environments was been sufficiently investigated.
In the past bird species were more numerous and frequent than today, even there are not data on specific surveys on bird population sizes in the area.
The few historical data available are mainly related to the period between the nineteenth and twentieth centuries and are reported in papers published by Graziano Vallon. It is almost always news provided by local informants and often not personally verified by the Friulan ornithologist.

This paper, which updates previous work (Parodi, 2003 and 2005), provides a summary of current knowledge regarding the bird population of the territories that fall within the boundaries of the Site of Community Importance (SCI) "Stella resurgences" that includes the greatest residual flaps of most typical and characteristic natural environments and the most numerous bird species reported. Moreover, in recent years the site has been the subject of specific investigations such as the collection of data relating to the implementation of the Atlas of the breeding species, currently being finalized.
The complete list of birds reported in the area is given in the Checklist where they are taken together 201 species, of which 87 are breeding.
In the discussion of individual species or groups of species, has given priority to the birds during the breeding season, even considering the fact that humid interior of the region are important, especially with regard to the bird community. Having to make a selection, we have chosen some of the most important species, the most easily observable and those which are of particular interest for the entire regional avifauna.
The information provided deals, unless otherwise indicated, the areas located within the SCI and refer, in most cases, to data collected in the area since 1980, including specific investigations by Roberto Parodi and Renato Castellani. In principle, provides essential information on the current status of the species dealt with any references to past situations.
