Great Tit (Parus major) Science Article 15 abstract Daily weight increments of nestling Great Tits are expressed as ratios of observed increment divided by the increment expected under favourable conditions. We used this ratio to examine the effects of local environmental conditions on nestling growth. We demonstrate a positive relationship between nestling growth and food […]

Metabolic response to temperature variation in the great tit: an interpopulation comparison
Great Tit (Parus major) Science Article 27 abstract We studied the resting metabolic rate (MR) from two great tit Parus major (Linnaeus) populations living in different winter regimes. Birds from the two different localities were exposed individually to +25 deg C, 0 deg C and -10 deg C for the night in three consecutive sessions […]
The costs of egg production and incubationin great tits (Parus major)
Great Tit (Parus major) Science Article 35 abstract The costs of egg production and incubation may have a crucial e
Spring temperatures and laying dates of first eggs of three passerines in Croatia
Great Tit (Parus major) Science Article 34 abstract This study is based on the spring temperaturesand laying dates of first eggs of threepasserines (sedentary: Great Tit, Parus majorand Tree Sparrow, Passer montanus; migratory:Starling, Sturnus vulgaris). Laying datesof first eggs were used as estimates of timingof breeding. The term ‘laying date’ is definedas the date of […]
Predator-induced take-off strategy in great tits(Parus major)
Great Tit (Parus major) Science Article 10 abstract When birds are attacked by predators the initial take-o
Pair bond and breeding success in Blue Tits Parus caeruleus and Great Tits Parus major
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 […]
The effect of fledging mass on the lives of Great Tits Parus major
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 tits (Parus major) reduce body mass in response to wing area reduction: a fieldexperiment
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 […]
Changes in foraging behaviour of the Coal Tit Parus ater due to snow cover.
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 […]
Moth abundance and breeding success in a Great Tit population where moths are the main nestling food
Great Tit (Parus major) Science Article 16 abstract The relationships between the timing of breeding and the reproductive success of Great Tits Parus major, and the phenology and abundance of the most abundant prey type in the nestling diet (Peridroma saucia moths, Lepidoptera, Noctuidae), were studied in orange groves in eastern Spain during three years.
