Active hiding of social information from information-parasites
2014
Background: Coevolution between pairs of different kind of entities, such as providers and users of information, involves reciprocal selection pressures between them as a consequence of their ecological interaction. Pied flycatchers ( Ficedula hypoleuca ) have been shown to derive fitness benefits (larger clutches) when nesting in proximity to great tits ( Parus major ), presumably because they this way discover and obtain information about nesting sites. Tits suffer from the resulting association (smaller clutches). An arms race between the tits (information host) and the flycatchers (information parasite) could thus result . Great tits often cover eggs with nesting material before, but no…

The last meal: large insects predominate the diet of the European Roller Coracias garrulus prior to population extinction
2019
Capsule: The diet of a European Roller Coracias garrulus population, approximately 10 years before its extinction, comprised of large-bodied orthopterans and coleopterans. Aims: To explore the diet composition of declining population of the European Roller. Methods: In 2005, 2006 and 2009, we monitored 18 nesting sites of the European Roller in southern Poland. Pellets and prey remain found in nest-holes were analysed. Results: In total, 1646 prey items were found. Orthoptera (60.4% of prey items) and Coleoptera (38.5%) predominated while vertebrates were caught rarely. Large-bodied species (orthopterans, bush-crickets, beetles Prionus coriarius and Cetonia aurata) including ground-dwellers…
