Small hand-gathering shellfisheries have not been associated with the major negative ecological impacts observed as a result of large-scale and long-term mechanical dredging of Mussel Mytilus edulis and Cockles Cerastoderma edule in the Dutch pa[...]

We investigated factors associated with the length of the post-fledging dependence period in 28 radio-tagged young Bonelli's Eagles Hieraaetus fasciatus monitored from 1998 to 2000. Under the assumptions of the Resource Competition Hypothesis (R[...]

The trade-off between brood size and offspring quality as predicted by life history theory, has been extensively studied in birds. However, in sexually size-dimorphic birds, where the larger sex requires more investment from the parents, the pot[...]

Parental investment in a breeding attempt involves trade-offs between current reproduction and adult survival and thus, future reproduction. Furthermore, the investment must be distributed between male and female offspring. In the present analys[...]

Great Tits Parus major can reduce fruit damage in apple orchards by predating on caterpillars. A model by Mols (2003) predicted that damage reduction is mainly influenced by the hatching date of the Great Tit nestlings and the number of breeding[...]

We analysed and compared body mass and capture-recapture data of a long distance migrant, the Reed Warbler Acrocephalus scirpaceus and of two partial and short-distance migrants, the Moustached Warbler A. melanopogon and the Cetti's Warbler Cett[...]

We compared the differences between spring and autumn in migration speed, fuelling rates and fuel loads of migrating Red Knots Calidris canutus. As a basis we used ringing data from Ottenby Bird Observatory southeastern Sweden, collected 1948-20[...]

Great Bittern Botaurus stellar-is is quoted as 'single-brooded', and replacement clutches were not proven until now. This paper describes three such cases in Belarus and France. Of 10 radio-tagged females that suffered nest failure, at least thr[...]

Young individuals of many passerines undergo a partial moult and replace most of their body feathers and a variable number of coverts and minor wing feathers. In many species, this moult generates perceptible coloration differences, which may ac[...]

Breeding success and adult survival of Redshank Tringa totanus on coastal meadows on Gotland, SE Sweden, was investigated in 1997-2003. Two periods with different breeding success could be detected. In 1997-1999, nest success varied between 43 a[...]
