The breeding biology of great tits (Parus major) was studied in two forests of maritime pine (Pinus pinaster) on the west coast of Portugal, 200 km apart: Leiria (north) and Apostiça (south). These two forests are located in a transition... more
The timing of breeding may not only affect breeding patterns such as the overlap of chick rearing period with the peak in food availability but also the opportunity for extra-pair mating. A negative relationship has been predicted between... more
As ground nesting homeotherms, alpine and arctic birds must meet similar physiological requirements for breeding as other birds, but must do so in more extreme conditions. Annual spring snowfall and timing of snow melt can vary by up to 1... more
Capsule Breeding performance was higher at inland colonies than on the coast due to higher nestling survival during late development. Aims To compare breeding performance of inland and coastal breeding Cormorants in England and Wales and... more
We studied whether pied flycatcher (Ficedula hypoleuca) and great tit (Parus major) females differed in quality between polluted and unpolluted habitats. Comparing female condition between incubation and nestling periods, we aimed at... more
1. Climate warming has led to shifts in the seasonal timing of species. These shifts can differ across trophic levels, and as a result, predator phenology can get out of synchrony with prey phenology. This can have major consequences for... more
Despite a numerical and functional dependence on microtine mammals, breeding northern harriers (Circus cyaneus) in New Brunswick preyed upon large numbers of young passerine birds following the hatch of their own nestlings. An independent... more
Laying date and clutch size in a population of the Blue Tit were evaluated during five years in a montane deciduous oak forest central Spain. By comparison with other Mediterranean and non-Mediterranean Blue Tit populations in the same... more
In this study we investigated the interplay between water level management, floating macrophytic vegetation and nesting whiskered tern (Chlidonias hybridus) during 8 years (1995–2002) at a shallow macrophyte-dominated lake in western... more
The condition-dependent model of optimal clutch size assumes body reserves required to initiate egg production include those for subsequent breeding phases. The threshold is expected to be similar among individuals, and hence postlaying... more
