Mit diesem umfassenden Handbuch wird das Hobby „Birding“ noch schöner und erlebnisreicher. Wie kann ich die Vögel in Deutschland, Österreich und der Schweiz beobachten? Wie kann ich Vögel zählen, wozu dient das Beringen und wie kann ich meine Erlebnisse in Bild und Ton festhalten? Angefangen bei den optischen Hilfsmitteln wie Fernglas oder Spektiv...

The paper describes the external changes of chicks of the Eurasian Oystercatcher (Haematopus ostralegus) from hatching to fledging. The downy plumage, bill, legs and eye-ring and the growth of plumage from the first until about the 40th day of life are treated and illustrated by photos. Average weight, wing lenght, bill length and bill depth are li...

In the boundaries of the Western Palearctic (WP) only two species of drongo are recorded as very rare vagrant: Black Drongo Dicrurus macrocercus and an Ashy Drongo D leucophaeus (Mitchell 2017). This paper documents the first records of Ashy Drongo for Iran and discusses the occurrence of this species in the 'greater' WP (i.e. including the Arabian...

Bei der Beobachtung eines Brutpaares von Steinröteln (Monticola saxatilis) oberhalb von Anras, Osttirol gelang ein interessanter Einblick in die Rolle der Bergeidechse (Zootoca vivipara) als Nestlingsnahrung dieses Fliegenschnäpperverwandten. ÖGH-Aktuell Vol. 56, Oktober 2020

Two juvenile Common Shelducks (Tadorna tadorna) were GPS-tagged in 2018 in Seewinkel, Austria to gather first data on the movements of this species' central European population.

Vögel Österreichs ("Birds of Austria") - the definite guidebook to all bird species of Austria.

As other species of wading birds, the lapwing suffers from habitat loss, habitat degradation and a progressing agricultural intensification. Still, nest predation has been identified as a key factor for little breeding success and declining populations, since predation rates are unsustainably high in many cases, even in otherwise favourable breedin...

Acoustic ranging allows identifying the distance of a sound source and mediates inter-individual spacing and aggression in territorial species. Birds and mammals are known to use more complex cues than only sound pressure level (SPL), which can be influenced by the signaller and signal transmission in non-predictable ways and thus is not reliable b...

This, the ninth report of the Austrian Rarities Committee (Avifaunistic Commission – AFK), details the observations of rare bird species in Austria in the years 2012-2014, with some additions to the previous reports covering 1980-2011, and one revision from before 1980. Accepted records (3.1) are listed in the systematic order of the latest availab...

In the last decades, lapwing populations decreased dramatically all across Europe due to shifts in land use and agricultural intensification. Knowledge of the threats to a species is essential to design appropriate conservation measures. Nest loss and insufficient productivity in the remaining habitats have been a main cause for declines. In this s...

This, the seventh report of the Austrian Rarities Committee (Avifaunistic Commission – AFK), details the observations of rare bird species in Austria in the years 2010-2011, with some additions to the previous reports covering 1980-2009, and a few further additions from years before 1980. Accepted records (3.1) are listed in the systematic order of...

This, the sixth report of the Austrian Rarities Committee (Avifaunistic Commission-AFK), details the observations of rare bird species in Austria in the years 2007–2009, with some additions to the previous reports covering 1980–2006, and a few further additions from years before 1980. Accepted records (4.1) are listed in the systematic order of the...

In winter 2008/09, about 4-5 million Bramblings Fringilla montifringilla formed a mass roost in south-eastern Austria (Lödersdorf, Styria), with the large part of individuals being present in the region from mid-November until the end of February. In February of the same winter, another large communal roost consisting of 1,5-3,5 million Bramblings...

This, the fifth report of the Austrian Rarities Committee (Avifaunistic Commission-AFK), covers the years 2001–2006, with some additions to the previous reports covering 1980–2000 and a few further additions from years before 1980. Accepted records are listed in the systematic order of the latest available Austrian bird list with the following deta...

This study presents an analysis of the influx of Bohemian Waxwings in winter 2004/05 into eastern Austria (the provinces Vienna, Lower Austria, Burgenland and Styria). The data set comprises 1,329 records of 62,604 individuals. Most of the records come from in and around the city of Vienna, as was the case for the previ- ous influx in 2000/01. The...
