Dans Journal of Ornithology (146(2) APR 2005)

We choose the European Nuthatch (Sitta europaea), an extremely socially monogamous passerine species, to investigate the breeding biology and frequency of extra-pair activities of females. Breeding individuals live in strong pair bonds for their[...]

Foraging flight distances as a measure of parental effort in blue tits Parus caeruleus differ with environmental conditions

M. J. Stauss, Auteur ; J. F. Burkhardt, Auteur ; J. Tomiuk, Auteur

Dans Journal of Avian Biology (36(1) JAN 2005)

Life-history theory predicts that parental effort in nestling provisioning is optimised in relation to the quality of individuals and/or their habitat. We studied the investment of breeding pairs of blue tits Parus caeruleus for their reproducti[...]
