Abstract: This paper presents the actual situation of the avifauna of the town named Sighişoara and its surroundings compared with the one in 1948. The species’ richness, phenological situation and repartition of species in different habitat types from the two periods of time chosen are compared and contrasted. The status of the avifauna in 1948 was evaluated from the manuscript of Fostrat (1948). The data from Fostrat (1948) were compared with data gathered by more recent studies, carried out in 2003, 2004 and 2005, all phenological phases being covered. The bird species’ composition was affected by the long term changes in the habitats from this area. A total number of 161 species has been recorded for both intervals under study. The forest clearings and the high anthropic impact on the forest habitats are documented by the disappearance of some species of large prey birds (Hieraaetus pennatus, Circaetus gallicus and Milvus migrans). As a consequence of the river regularization species relying on the vegetation that characterises the large flooded areas (Nycticorax nycticorax, Circus aeruginosus, Rallus aquaticus, Locustella luscinioides, Acrocephalus schoenobaenus and Emberiza schoeniclus) have not been recorded anymore, while new species, depending on the recently-formed permanent ponds (Tachybaptus ruficollis, and Ixobrycus minutus) have occurred.
KEYWORDS: avifauna, long term changes, Sighisoara.
