The Role of the Eurasian Sparrowhawk (Accipiter nisus) in the Decline of the House Sparrow (Passer domesticus) in Britain

  author={Christopher Paul Bell and Samantha Baker and Nigel G. Parkes and Michael de L. Brooke and Dan E. Chamberlain},
ABSTRACT. We compared the pronounced geographic pattern in the recolonization of Britain by the Eurasian Sparrowhawk (Accipiter nisus) from 1970 onward with the spatiotemporal pattern among House Sparrow (Passer domesticus) populations over the same period, using data on the occurrence of both species at garden feeding stations. Using a simulation of House Sparrow population trends based on a logistic model that incorporated a predation index derived from Eurasian Sparrowhawk incidence… 

Evidence that population increase and range expansion by Eurasian Sparrowhawks has impacted avian prey populations

Consistently negative associations across the range of analyses in a number of species, including Tree Sparrow, Bullfinch and Redpoll, strongly suggest that local population decline is precipitated by the settlement of Sparrowhawk in areas from which they have been previously absent.

Urban House Sparrow (Passer domesticus) populations decline in North America

ABSTRACT House Sparrow (Passer domesticus) populations declined across much of their global range in the late 20th century. Most research examining this decline is conducted in the species' native

Record breeding densities of Frances's Sparrowhawk Accipiter francesiae, and effects on bird communities in the Comoros

In two study plots on Mayotte Island, the territorial, neotenic-endemic race brutus of the Frances's Sparrowhawk occurred at world-record breeding densities for a small raptor of 2.0- 2.6 ha/pair,

House Sparrows Passer domesticus and Tree Sparrows Passer montanus: Fine-Scale Distribution, Population Densities, and Habitat Selection in a Central European city

Abstract. Populations of House and Tree Sparrows have rapidly declined in various breeding habitats throughout their European distribution range; however, the strongest decline was recorded within

Breeding Success and Productivity of Urban and Rural Eurasian Sparrowhawks Accipiter nisus in Scotland

ABSTRACT The conversion of rural habitat into built-up areas often affects animal species negatively. However, some generalist bird species and raptors relying on avian prey have colonised urban

Roosting of tree sparrow (Passer montanus) and house sparrow (Passer domesticus) in white stork (Ciconia ciconia) nests during winter

Presented are the results of a preliminary study on wintering and roosting sparrows in white stork nests. The study was conducted in the winters of 2005/2006 and 2006/2007 in the agricultural

Advanced Autumn Migration of Sparrowhawk Has Increased the Predation Risk of Long-Distance Migrants in Finland

It is demonstrated that passerines show very conservative response in autumn phenology to climate change, and thus phenological mismatches caused by global warming are not necessarily increasing towards the higher trophic levels.

The house sparrow in the service of basic and applied biology

The natural history of house sparrows is reviewed, what the study of these birds has meant to bioscience generally is highlighted, and the many resources available for future work on this species are described.

itizen science in action — Evidence for long-term , region-wide House parrow declines in Flanders , Belgium reet

Urban expansion is detrimental for many species. While the House Sparrow (Passer domesticus) initially flourished in the vicinity of men, a decline in House Sparrow numbers has been observed in

Habitat preferences of two sparrow species are modified by abundances of other birds in an urban environment

It is indicated that associations between food resources, habitat covers, and the relative abundance of two sparrow species are altered by the abundance of other urban species, which may be responsible for these interactive effects.



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

Sparrowhawk Accipiter nisus presence and winter bird abundance

The significant negative effects detected suggest that there is a temporal matching between increased predation pressure and decreases in bird abundance for certain species, but there was no strong evidence that Sparrowhawk re-colonisation was linked to long-term declines in population size.

The status of the urban house sparrow Passer domesticus in north-western Europe: a review

The aim of this paper is to provide a summary of the present status of the house sparrow in urban areas in north-western Europe and to identify those areas of research that will provide the necessary evidence to understand what is going on.

Biology of the Ubiquitous House Sparrow: From Genes to Populations

The role of the House Sparrow in disease transmission to humans and their domesticated animals, and sexual selection and the function of the male badge in the species are explored.

The widespread declines of songbirds in rural Britain do not correlate with the spread of their avian predators

Large–scale, long–term data from a national bird census scheme is used to examine whether magpies and sparrowhawks could have depressed the rates of year–to–year population change in 23 songbird species, finding that they are unlikely to have caused songbird declines.

Prey Selection by Sparrowhawks, Accipiter nisus: Relative Predation Risk for Breeding Passerine Birds in Relation to their Size, Ecology and Behaviour

Most predation was due to the smaller male hawks, providing food for their mates and young, RPR increased with prey body size up to a mass of about 40 g, then declined with increasing body size (larger prey being more difficult to catch), RPR decreased with increasing relative density of prey species.

Apparent lack of impact of Sparrowhawks on the breeding densities of some woodland songbirds

Most species increased in density over the whole study period and, in four, the rate of increase slowed towards the end of the study, although it was impossible to tell whether this slowing in population growth was caused by the return of Sparrowhawks or by other factors, such as habitat effects.

Migration Counts of Raptors at Hawk Mountain, Pennsylvania, as Indicators of Population Trends, 1934-1986

ABSTRACr.--Counts migrating hawks were initiated in 1934 at Hawk Mountain and, except for 1943-1945, have continued to the present. We analyzed the data from 1934-1986 by a standardized sample period

Recovery of a sparrowhawk population in relation to declining pesticide contamination

It is suggested that recovery of the sparrowhawk population was primarily dependent on declining HEOD contamination, with a resulting improvement in survival, and the decline in DDE contamination may have assisted the population increase.

The decline of the House Sparrow: a review

The House Sparrow Passer domesticus population in Britain suffered a major decline in the 1920s, particularly in built-up areas, which coincided with the replacement of the horse by the internal
