Heron colonies are dynamic components of wetlands. Therefore, their systematic monitoring is important for the management of both birds and wetlands. During the period 1988–2018, we counted breeding pairs of seven colonial breeding heron species at 65 colonies across 37 wetlands in Greece. We considered as annual variables of a population: (a) year...

Purpose/Objective: Greece is one of golden jackal’s historical strongholds in Europe, although its range and populations have undergone a significant decline in the country since the 1970s until the 1990s. Based on literature, by the 1990s the species’ distribution had considerably shrunk and comprised of only isolated populations in southern (Pelo...

Urban and suburban areas are among the fastest-growing land-use types globally, reducing and fragmenting natural habitats for many animal species and making human-wildlife interactions more common. However, cities also create habitat for several species considered urban tolerant or urban exploiter species. Additionally, the environmental characteri...

The Glossy Ibis Plegadis falcinellus is a well-known bird species in Greece since antiquity as evidenced by many ancient texts. In recent times, the species was initially confirmed nesting in 1960, in a colony consisting of approximately 1,000 pairs at Evros Delta, northeastern Greece and a few years later at three more wetlands.

The Vjosa/Aoos river still flows freely from the Pindus mountains in Greece, to the river mouth in Albania largely without artificial obstacles. The river stretches for 270km in total and 70km are flowing within the Greek area. Downstream of the Pigai dam in Greece (10km from the springs of Aoos), the river is near natural, representing all types o...

Greece is one of golden jackal’s historical strongholds in Europe, although its range and populations have notably declined over the last 25 years. Until recently the species has been reported to survive in discontinuous, isolated population clusters in southern Greece (Peloponnese), in central Greece (Fokida), in northern Greece (Chalkidiki) and i...

Για πρώτη φορά στην διεθνή βιβλιογραφία, παρουσιάζονται προκαταρκτικά δεδομένα που ερμηνεύουν πιθανώς την εποχιακή παρουσία των Κιρκινεζιών στους ορεινούς βοσκότοπους της Πίνδου. Κατά του θερινούς μήνες στην ευρύτερη περιοχή των Ιωαννίνων έχουν καταγραφεί σημαντικοί αριθμοί (έως και πάνω από 3.500 άτομα) Κιρκινεζιών (Falco naumanni). Την εποχή αυτή...

Ένας μικρός πληθυσμός του παγκοσμίως απειλούμενου Κιρκινεζιού (Falco naumanni) επιβιώνει στα Ιωάννινα, ενώ το είδος έχει σχεδόν εξαφανιστεί στη Δυτική Ελλάδα, εκτός από ελάχιστες αποικίες όπου πρόσφατα εφαρμόζονται υποτυπώδεις δράσεις διατήρησης. Τα τελευταία 10 έτη (2000-2010) διερευνήσαμε τις προμεταναστευτικές συγκεντρώσεις του στην ευρύτερη περ...
