Provisioning behaviour in relation to food availability and nestling food demand in the Water Pipit Anthus spinoletta

Water Pipit (Anthus spinoletta) Science Article 3 abstract Insufficient food provisioning by parents can reduce growth rate of altricial nestlings, their size and weight at fledging, and also affect survival. Therefore at low food availability, parents should increase their food provisioning effort. In insectivorous Water Pipits Anthus spinoletta prey biomass differed up to 50 times […]

The impact of grazing animals on nesting success of grassland passerines in farmland and natural habitats: a field experiment

Water Pipit (Anthus spinoletta) Science Article 1 abstract A study was made of the influence of trampling by grazing animals on the nesting success of real nests (meadow pipit, Anthus pratensis; water pipit, Anthus spinoletta; and skylark, Alauda arvensis) and simulated nests (caps from jam-jars filled by green plasticine) on pasture in the Orlicke Mountains […]

Territory quality and reproductive success: Can water pipits Anthus spinoletta assess the relationship reliably?

Water Pipit (Anthus spinoletta) Science Article 2 abstract Variation in avian reproductive success is often caused by differences among territories in food supply, safety from predators and microclimatic conditions at the nest. Yet, in some habitats these components of territory quality, and hence future reproductive success, are difficult to assess at the time of settlement. […]
