Great Tit (Parus major) Science Article 14 abstract Density dependent processes and the availability of food may play an important role in the determination of population size. To investigate the relationship between density and local survival of juvenile Great Tits Parus m. major Kluyer removed first brood fledglings in two years. An analysis is presented […]

Great Tit (Parus major) Science Article 6 abstract The ornithological journals tend to publish the first observation of a fact or behaviour (e.g. Rolando & Zunino, 1992; Putnam, 1996; Dijkstra et al., 1997; Lozano & Lemon, 1998), but later observations of the same topic are usually not published, or they are published in very local […]

Great Tit (Parus major) Science Article 33 abstract Data from 939 nests of the Blue Tit Parus caeruleus and 1008 nests of the Great Tit P. major from nestboxes provided in superabundance in mixed forest study sites between 1976 and 2001 were analysed to examine the effects of mate retention on breeding success and the […]

Great Tit (Parus major) Science Article 4 abstract Studies of ringed Great Tits Parus major have shown that the mass of fledglings has a major impact on their futures . Heavier chicks are more likely to survive to breed and birds which are larger at fledging remain larger birds for the whole of their lives […]

Great Tit (Parus major) Science Article 36 abstract Flight performance is crucial in determining whether a small bird will survive an attack by a predator. Given the importanceof body mass in determining flight performance, it has been suggested that birds should strategically regulate body mass as aresponse to predation risk. However, all experiments up to […]

Great Tit (Parus major) Science Article 18 abstract This paper studies the foraging behaviour of the Coal Tit Parus ater, a small passerine wintering in mountain coniferous forests in the Pyrenees. We compared tree site use and the foraging techniques of birds, (1) under snowy conditions, when snow covered the outer substrates of pines, and […]

Great Tit (Parus major) Science Article 7 abstract Social relationships within a Great Tit Parus major population in a mountainous area in central Spain under winter conditions and in two consecutive years were studied. Three hierarchical classes were established using aggressive interactions between the individuals over artificial feeders: dominants, subdominants and subordinates. Sex, age and […]
