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. […]

Nightjar Caprimulgus europaeus and Woodlark Lullula arborea – recovering species in Britain?

Tree Pipit (Anthus trivialis) Science Article 2 abstract The Nightjar Caprimulgus europaeus and Woodlark Lullula arborea are identified as species of conservation concern at both a UK and a European level on account of historical declines in their population sizes and ranges.

Influences of restock age and habitat patchiness on Tree Pipits Anthus trivialis breeding in Breckland pine plantations

Tree Pipit (Anthus trivialis) Science Article 1 abstract The British Tree Pipit Anthus trivialis population has shown a marked decline in recent decades, together with a range contraction that has been most apparent in central and southeast England. In East Anglia, the species is now largely restricted to heathland and, in particular, the conifer plantations […]
