Richard M. Francksen, Auteur ; Mark J. Whittingham, Auteur ; Sonja C. Ludwig, Auteur ; Staffan Roos, Auteur ; David Baines, AuteurPredators will often respond to reductions in preferred prey by switching to alternative prey resources. However, this may not apply to all alternative prey groups in patchy landscapes. We investigated the demographic and aggregative numerical a[...]Article
Philip Warren, Auteur ; Tom Hornby, Auteur ; David Baines, AuteurCapsule: Breeding Grey Partridges Perdix perdix on hill farms preferred Soft Rush-infested rough grazing which provided nesting cover and invertebrates for foraging chicks.Aims: To measure habitat use, nest sites, chick diet and breeding product[...]Article
David Baines, Auteur ; Michael Richardson, Auteur ; Philip Warren, AuteurCapsule: Conservation programmes for Black Grouse Tetrao tetrix need to consider managements that increase invertebrates for chicks.Aims: To compare invertebrates in chick diet between habitat and region and to relate abundance of preferred inve[...]Article
Richard M. Francksen, Auteur ; Mark J. Whittingham, Auteur ; Sonja C. Ludwig, Auteur ; David Baines, AuteurCapsule: The winter diet of Common Buzzards Buteo buteo on a Red Grouse Lagopus lagopus scotica moor was dominated by small mammals, whilst grouse were a minor prey item.Aims: To assess winter diet of Common Buzzards from pellets collected at ro[...]Article
