Thekla Lark (Galerida theklae) Science Article 1 abstract Parental body mass changes during the nesting period were analysed for Thekla Larks,Galerida theklae, and Lesser Short-toed Larks, Calandrella rufescens. Body mass of femaleThekla Larks declines from the start of incubation until the chicks fledge; laying date,interpreted as the number of renesting attempts, also has a negative […]

Spatial and temporal distribution of breeding Skylarks Alauda arvensis in relation to crop type in periods of population increase and decrease .
Sky Lark (Alauda arvensis) Science Article 1 abstract The seasonal variation in Skylark Alauda arvensis occurrence, in terms of both presence and abundance, was examined in relation to crop type on a number of survey sites in English lowland farmland in two periods, 1965-70 and 1990-95 . These two periods were selected to coincide with […]
Seasonal and interannual variability in laying date, clutch size, egg volume and hatching asynchrony of four lark species in Mediterranean Spain
Sky Lark (Alauda arvensis) Science Article 6 abstract To describe the variation in laying date, clutch size, egg volume and hatching asynchrony of four lark species (Skylark Alauda arvensis, Short-toed Lark Calandrella brachydactyla, Thekla Lark Galerida theklae and Lesser Short-toed Lark Calandrella rufescens) and at two different time scales: between years (large-scale variation), and within […]
Abundance of Four Lark Species in Relationto Portuguese Farming Systems
Sky Lark (Alauda arvensis) Science Article 2 abstract Throughout much of Europe, farmland birds have declined more than those of other habitats, because of the abandonment of traditional farming systems and the simplification of remaining agricultural systems, including increased use of external inputs (Tucker & Heath 1994, Baldock 1991, Bignal & McCracken 1996). Traditional low-input […]
Sustainable Arable Farming For an Improved Environment (SAFFIE): managing winter wheat sward structure for Skylarks Alauda arvensis
Sky Lark (Alauda arvensis) Science Article 5 abstract Research has shown a close correlation between the decline of the UK Skylark Alauda arvensis population and the replacement of spring-sown cereals with winter-sown varieties, in which advanced sward development prevents successful multiple nesting attempts and reduces access for foraging. Widescale reversal of sowing times is unlikely […]
Do habitat association models have any generality? Predictingskylark Alauda arensis abundance in different regions of southernEngland
Sky Lark (Alauda arvensis) Science Article 3 abstract Much of conservation science is based upon determining the use by organisms ofdifferent resources. However, the field data used to construct habitat associationmodels generally come from a small number of sites covering a fraction of the areaof interest. It is important therefore to assess the generality of […]
The impact of grazing animals on nesting success of grassland passerines in farmland and natural habitats: a field experiment
Sky Lark (Alauda arvensis) Science Article 4 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 […]
Parental body mass changes during the nestingstage in two Lark species in a semi-arid habitat
Short-toed Lark (Calandrella brachydactyla) Science Article 1 abstract Parental body mass changes during the nesting period were analysed for Thekla Larks,Galerida theklae, and Lesser Short-toed Larks, Calandrella rufescens. Body mass of femaleThekla Larks declines from the start of incubation until the chicks fledge; laying date,interpreted as the number of renesting attempts, also has a negative […]

Parental body mass changes during the nestingstage in two Lark species in a semi-arid habitat
Lesser Short-toed Lark (Calandrella rufescens) Science Article 1 abstract Parental body mass changes during the nesting period were analysed for Thekla Larks,Galerida theklae, and Lesser Short-toed Larks, Calandrella rufescens.
