This thesis investigates nesting success, foraging behaviour, chick diet and growth of three ecologically contrasting species (skylark Alauda arvensis, yellowhammer Emberiza citrinella and song thrush Turdus philomelos) on farmland, in relation to microhabitat and the availability of invertebrates. Fieldwork was conducted on a lowland mixed arable farm in Leicestershire over the breeding seasons 2000 - 2002. Telemetry was used to monitor adult song thrushes and fledgling skylarks. Skylark nest density was highest in set-aside and lowest in crops, yellowhammer nest density was greatest in herba

Streszczenie:

Many species of farmland birds have shown huge declines in numbers and range since the 1970s due to agricultural intensification, and these declines have been worst amongst granivorous species. Recent studies have suggested that low abundance of invertebrate chick food may have been important in driving the declines of a number of granivorous species, however causation has still only been proved for the Grey Partridge, whose decline has been attributed to low chick survival due to the indirect effects of herbicides reducing invertebrate abundance. We investigated invertebrate declines and how

1. Many species of bird breeding in Britain have declined in recent decades. However, only in the farmland ecosystem are the majority of species, primarily seed-eating passerines, declining. Similar declines in these species are also occurring elsewhere in Europe and North America. This thesis aims to model the effects of habitat change on population size ofthese species through an understanding of their behaviour. 2. A wide range of factors, primarily relating to the intensification of agricultural management, have been implicated in these declines, and these are reviewed in detail. There is

Green lanes (two hedgerows separated by an unmetalled farmland track) have only just begun to have their potential for wildlife recognised within farmland, with a few studies revealing their substantial benefits for butterflies, bees and wild flowers. This study examines the value ofgreen lanes for farmland birds, comparing 20 green hi.ries with paired single hedgerows around Chester, UK over the years 2002-2004.

In this thesis, I aim to assess how farmland birds use insect-rich agri-environment scheme (AES) foraging habitats during the breeding season and how such birds might benefit from them. It is particularly focused on how the coverage and quality (measured by insect food levels and food accessibility) of AES habitats influence territory selection, foraging activities and breeding success. The thesis begins by explaining why farmland birds have declined, reviewing how AES may help reverse these trends, along with outlining why AES may fail to benefit breeding birds (Chapter one).

Agricultural environments are critical to the conservation of biota throughout the world. This is due both to the limited extent of current reserve systems and the large, and still expanding, proportion of terrestrial environments already dominated by agricultural land-uses. Consequently, there is a growing call from scientists around the world for the need to maximise the conservation value of agricultural environments.

High Nature Value farmland (HNVf) refers to traditional agricultural landscapes which support high levels of biodiversity. HNVf is declining across Europe, through both intensification and abandonment, raising concerns about the conservation of species associated with it. One argument is that such HNV species are better described as being dependent on disturbance, and that management practices on HNVf mimics the effects of natural disturbance processes such as herbivory, fire, severe weather and flooding, which are often suppressed across much of Europe.

Reaching the EU target for renewable energy is likely to encourage a rapid expansion of biomass crop production in the UK. This expansion could pose a considerable threat to farmland birds, via the loss of suitable nesting habitat for ground-breeding birds or by decline in availability and accessibility of foraging resource for other farmland birds. Alternatively, the low-input management of biomass crops may provide benefits over more intensively managed arable crops. The potential impacts of biomass expansion on nesting and foraging opportunities were therefore investigated by examining the

Widespread extinction is a critical threat to biodiversity and is largely caused by human overexploitation of habitat and populations. A widely used and hence well studied organism group for indication of biodiversity is birds. In Europe especially, farmland specialists have suffered from intensified agricultural practices such as increase of monoculture, use of pesticides, and heavy machinery. This has been shown to be partly caused by an EU legislation called the Common Agricultural Policy (CAP).

Extensive farmland ecosystems are widespread and biodiversity-rich, yet they face important human pressures since the beginning of agriculture intensification, which is leading them into a severe biodiversity crisis. As a result, farmland bird populations - particularly specialist species such as steppe birds - are declining dramatically. In Europe, steppe birds are associated with “cereal steppes”, which are extensive agricultural landscapes where crop rotations include fallow fields. Fallows are key breeding and foraging habitats for farmland birds and usually present open vegetation structu

Knowledge of the shape of the relationship between biodiversity and intensity is necessary to determine both where conservation policies will be most effective and how to allocate intensity to reconcile production and biodiversity.

Farmland bird populations in Europe have been in decline for a long time. Agricultural intensification and growing a large share of crops that provide suboptimal breeding habitat could be the main causes of the observed decline. To explore these possible drivers, I focused on population trends of farmland bird species in different habitats in the Czech Republic over the periods 1982-1990 and 1990-2010. Specifically, I focused on the variability in trends within each species in respect to the differences in landscape management between the lowlands and mid-altitude areas before and after 1990.

The populations of many farmland birds have severely declined during the past years. Even (formerly) common species such as the Eurasian Skylark (Alauda arvensis) and the Northern Lapwing (Vanellus vanellus) are strongly affected. The declines were mainly caused by agricultural intensification. In response to the declines, agri-environmental schemes (AES) that integrate protection objectives into agricultural practices are a promising strategy. Until 1992 all EU member states were obliged to develop agri-environment programmes and since this time, AES are widely used. AES are often criticised
