House-sparrow populations have declined sharply in Western Europe in recent decades, but the reasons for this decline have yet to be identified, despite intense public interest in the matter. Here we use a combination of field experimentation, genetic analysis and demographic data to show that a reduction in winter food supply caused by agricultural intensification is probably the principal explanation for the widespread local extinctions of rural house-sparrow populations in southern England… 

Mass-dependent predation risk as a mechanism for house sparrow declines?

It is shown that changes in house sparrow mass and thus fat reserves are not regulated to minimize starvation risk, as would be expected if limited winter food were the only cause of population decline, and appears to be responding to mass-dependent predation risk.

Depleted suburban house sparrow Passer domesticus population not limited by food availability

It is concluded that this depleted suburban sparrow population is not limited by food availability, and conservation efforts based primarily on food provision are unlikely to succeed, and further research is merited into the potential impacts of air pollution.

Urbanization, nestling growth and reproductive success in a moderately declining house sparrow population

The reproductive success of urban and rural sparrows in a central European country, Hungary is investigated, finding that rural pairs produced more and larger fledglings than suburban pairs, and the difference remained consistent in two years with very contrasting meteorological conditions during breeding.

Size and trends of the House Sparrow Passer domesticus population in Great Britain

House Sparrow Passer domesticus populations have declined throughout Europe over the last two to three decades; this is of particular concern in urban areas. We analysed data from extensive census

Assessing habitat quality of farm-dwelling house sparrows in different agricultural landscapes

It is suggested that simplified landscapes constitute a poorer feeding environment for house sparrows during breeding, that the population-regulating mechanisms in the landscapes differ, but that predation risk is the same across the landscape types.

The House Sparrow Passer domesticus is traditionally associated with human habitation. However, the species has undergone dramatic declines in many urban areas in north-western Europe. There are many

The Swallow and the Sparrow: how agricultural intensification affects abundance, nest site selection and competitive interactions

Evidence of interspecific competition between these species is provided, highlighting the indirect role of anthropogenic alterations on agro-ecosytems and illustrating a landscape-mediated avian competition pressure that has, to the authors' knowledge, never been documented in farmscapes.

Low genetic differentiation in a sedentary bird: house sparrow population genetics in a contiguous landscape

The genetic diversity and differentiation of the house sparrow populations across Finland in the 1980s are studied, at the onset of the species' decline in abundance, to provide a benchmark for conservation biologists and emphasize the influence of landscape structure on gene flow.
