In this paper, the main aspects of agricultural intensification that have led to population declines in farmland birds over the past 50 years are reviewed, together with the current state of knowledge, and the effects of recent conservation actions. For each of 30 declining species, attention is focused on: (1) the external causes of population declines, (2) the demographic mechanisms and (3) experimental tests of proposed external causal factors, together with the outcome of (4) specific… 

Analysis of trends and agricultural drivers of farmland bird declines in North America : A review

Globally, agriculture has intensified during the past 50 years due to increased mechanization, changes in the timing of farming operations, grassland conversion to cropland, and increased

The role of natural habitats in agricultural systems for bird conservation: the case of the threatened Lesser Grey Shrike

Birds of agricultural systems are one of the most threatened groups of birds in Europe mainly due to their sharp population decline in recent decades. Habitat intensification resulting from more

The state of play of farmland birds: population trends and conservation status of lowland farmland birds in the United Kingdom

Many bird species of lowland farmland have declined substantially in the United Kingdom over the past 30 years. Declines among farmland specialists are steeper than for generalists and were most

Breeding season food limitation drives population decline of the Little Owl Athene noctua in Denmark

TLDR
Experimental food supplementation to breeding pairs increased the proportion of eggs that resulted in fledged young from 27 to 79%, supporting the hypothesis that the main proximate reason underlying the ongoing population decline is reduced productivity induced by energetic constraints after egg-laying.

Estimating effects of arable land use intensity on farmland birds using joint species modeling

TLDR
It is found that interventions aimed specifically at land in production could provide benefits to farmland birds and this approach is well suited for evaluating agricultural policies by providing evidence for or against certain interventions or to be linked to policy scenarios of land use change.

Understanding changes in bird populations – the role of bird marking

Studies of marked birds play a central role in research on avian population dynamics and life histories because they are the main means of estimating survival, recruitment and dispersal. Integrated

Agriculture modifies the seasonal decline of breeding success in a tropical wild bird population

TLDR
This work investigates the mechanisms linking agricultural land use with breeding success using long‐term data for the formerly Critically Endangered Mauritius kestrel Falco punctatus, a tropical forest specialist that also occupies agricultural habitats to focus on the relationship between breeding success, agriculture and the timing of breeding.

TLDR
The results suggest that recent trends in agriculture have had deleterious and measurable effects on bird populations on a continental scale and predict that the introduction of EU agricultural policies into former communist countries hoping to accede to the EU in the near future will result in significant declines in the important bird populations there.

The state of play of farmland birds: population trends and conservation status of lowland farmland birds in the United Kingdom

Many bird species of lowland farmland have declined substantially in the United Kingdom over the past 30 years. Declines among farmland specialists are steeper than for generalists and were most

The importance of variation in the breeding performance of seed‐eating birds in determining their population trends on farmland

TLDR
Variation in annual survival and fledgling production per breeding attempt alone could not explain changes in abundance for at least seven species, and this may suggest that changes in post-fledging survival rates and/or the number of breeding attempts per year could have been important.

Linking agricultural practice to insect and bird populations: a historical study over three decades

TLDR
Data from a broad suite of species provide support for linked temporal change between farmland birds, invertebrate numbers and agricultural practice in Scotland, and are consistent with the view that agricultural change has influenced birds through changes in food quality or quantity.

Changes in the abundance of farmland birds in relation to the timing of agricultural intensification in England and Wales

1. Over the past three decades changes in agricultural management have resulted in increased crop and grass production. This intensification has been accompanied by population declines among farmland

Trends in the abundance of farmland birds: a quantitative comparison of smoothed Common Birds Census indices

TLDR
Novel, quantitative approaches to the interpretation of abundance indices from which reliable inferences about conservation status can be made are described, revealing critical periods during which populations are likely to have been affected by environmental change.

The management of lowland neutral grasslands in Britain: effects of agricultural practices on birds and their food resources

TLDR
There is now a need to improve understanding of how grassland management affects bird population dynamics, and the interaction between predation rates and management-related changes in habitat is particularly important.

The winter distribution of seed‐eating birds: habitat structure, seed density and seasonal depletion

To understand the reasons for population change we need to understand the mechanisms through which it occurs. Throughout western Europe there have been declines in farmland birds. These declines have

Changes in bird populations on sample lowland English farms in relation to loss of hedgerows and other non-crop habitats

TLDR
It is suggested that other processes, such as habitat degradation, may have caused a baseline population decline in at least 10 farmland bird species and that declines may have been exacerbated by localised habitat loss.

The Contribution of Some Recent Research on Birds to Ecological Understanding

TLDR
The contribution to ecological understanding of four aspects of ornithological research, based on long-term or large-scale studies are discussed, including the application of island biogeography and metapopulation theory to the bird populations of woods and other fragmented habitats and the importance of the stochastic processes of local extinction and recolonization in influencing species numbers and distributions among fragments.
