Article
Norbert Schaffer, Auteur ; Bruno A. Walther, Auteur ; Kim Gutteridge, Auteur ; Carsten Rahbek, AuteurThere is a clear need for protection of the migration and wintering grounds of the Globally Threatened Aquatic Warbler Acroccphalus paludicola, but little is known about them and the threats they face. To narrow this gap, a desk study was perfor[...]
Article
Frank Wugt Larsen, Auteur ; Jesper Bladt, Auteur ; Andrew Balmford, Auteur ; Carsten Rahbek, Auteur1. Most biodiversity is still unknown, and therefore, priority areas for conservation typically are identified based on the presence of surrogates, or indicator groups. Birds are commonly used as surrogates of biodiversity owing to the wide avai[...]

Breeding season food limitation drives population decline of the Little Owl Athene noctua in Denmark
Kasper Thorup, Auteur ; Peter Sunde, Auteur ; Lars B. Jacobsen, Auteur ; Carsten Rahbek, AuteurMany farmland bird species have declined markedly in Europe in recent decades because of changes in agricultural practice. The specific causes vary and are poorly known for many species. The Little Owl, which feeds extensively on large invertebr[...]

Anders P. Tottrup, Auteur ; Kasper Thorup, Auteur ; Carsten Rahbek, AuteurDans Ardea (94(3) 2006)Although studies of changes in the timing of passerine spring migration are numerous, less is known about timing of their autumn departure. We present phenological data on 22 species based on mist-netted birds caught on the Baltic island of Chri[...]

Niels Strange, Auteur ; Bo Jellesmark Thorsen, Auteur ; Jesper Bladt, Auteur ; Kerrie A. Wilson, Auteur ; Carsten Rahbek, AuteurBiodiversity conservation policies focus on securing the survival of species and habitats according to their current distribution. This basic premise may be inappropriate for halting biodiversity decline under the dynamic changes caused by clima[...]

Mathilde Lerche-Jorgensen, Auteur ; Lars Maltha Rasmussen, Auteur ; Michael Bodker Clausen, Auteur ; Carsten Rahbek, Auteur ; Kasper Thorup, AuteurThe number of breeding pairs of Montagu's Harrier Circus pygargus in Denmark has been declining since the beginning of the 1980s and the species is now mainly confined to the Wadden Sea area between the Romo Dam and the Danish/German border. The[...]
Article
Jorgen Rabol, Auteur ; Carsten Rahbek, AuteurLarge numbers of migrant passerines were ringed during spring and autumn on the small Danish island of Christianso in the Baltic Sea. For the period 1976-1996 we investigated the population trends using catches (corrected for trapping effort) of[...]
Article
Dorthe Pedersen, Auteur ; Kasper Thorup, Auteur ; Peter Sunde, Auteur ; Lars Bo Jacobsen, Auteur ; Carsten Rahbek, AuteurBefore dispersal, social and spatial behaviour in owls has only been briefly studied. We used radio tracking to monitor age-influenced social and spatial behaviour in 10 juvenile Little Owls (Athene noctua) from nests in Northern Jutland, Denmar[...]
