Willow Tit (Parus montanus) Science Article 2 abstract The Magadan region of northeastern Siberia. Clutch size and number of fledglings averaged 7.5 and 6.5, respectively, and both were correlated negatively with the date of the first egg. Nestling growth rate was correlated positively with the date of the first egg, but was not related to […]

Hunger-dependency of hiding behaviour after a predator attack in dominant and subordinate Willow Tits.
Willow Tit (Parus montanus) Science Article 3 abstract We studied rank-specificity of predation risk taking in captive Willow Tits Parus montanus. Level of risk taking was expressed by duration of hiding after a simulated predator attack. By manipulating available food, we separated the effects of hunger and other rank associated factors on accepted predation risk. […]
Factors influencing Willow Tit Poecile montanus site occupancy: a comparison of abandoned and occupied woods
Willow Tit (Parus montanus) Science Article 4 abstract The British Willow Tit Poecile montanus kleinschmidti underwent a decline of 85% between 1970 and 2003. The cause of this decline is unknown. However, several hypotheses have been put forward to account for it: competition from other tit species, predation by Great Spotted Woodpeckers Dendrocopos major and […]
Growth and size of Willow Tit Parus montanus under different environmental conditions
Willow Tit (Parus montanus) Science Article 1 abstract This six years study focuses on the effect of environmental factors on Willow Tit (Parus montanus) nestling growth . For each brood, nestling growth during the growth period (day 1-12) was related to the amount of food and temperature du ring this peri od as well as […]
Timing and synchronisation of breeding in a Marsh Tit Parus palustris population from a primaeval forest
Marsh Tit (Parus palustris) Science Article 2 abstract Marsh Tits Parus palustris in Bialowieza National Park (E. Poland, 1985-97) were single brooded, laid their first eggs between 5 April and 11 May (mean 21 April). Nest building commenced on average 10-15 days before the first egg was laid, but overlapped partially with egg laying. Median […]
Seasonal decline in clutch size of the Marsh Tit (Parus palustris) in relation to date-specific survival of offspring
Marsh Tit (Parus palustris) Science Article 1 abstract This paper documents and evaluates seasonal trends in reproductive performance in the Marsh Tit (Parus palustris)in southern Sweden. Clutch size decreased for nests started later in the season. This pattern held true both for second-year and older females when analyzed separately In dividual females adjusted clutch size […]
Habitat selection by Marsh Tits Poecile palustris in the UK
Marsh Tit (Parus palustris) Science Article 3 abstract The Marsh Tit Poecile palustris is a small, hole-nesting woodland passerine whose national population in the UK has declined by more than 50% in the last 25 years. To investigate possible causes for the species long-term decline, we examined habitat selection by Marsh Tits at three scales. […]
