Bandicoot bunkers: training wild-caught northern brown bandicoots (Isoodon macrourus) to use microchip-automated safe refuge

Abstract Context. Soft-release involving supplementary feeding or shelter is commonly used in wildlife reintroduction and rehabilitation projects. However, competition for nestboxes and supplementary

Faecal metabarcoding reveals pervasive long-distance impacts of garden bird feeding

It is suggested that the impacts of supplementary feeding are larger and more spatially extensive than currently appreciated and could be disrupting population and ecosystem dynamics.

Relative Roles of Grey Squirrels, Supplementary Feeding, and Habitat in Shaping Urban Bird Assemblages

It is found that grey squirrels slightly reduced the abundance of breeding bird species most sensitive to squirrel nest predation by reducing the beneficial impact of woodland cover, and urban bird populations are more likely to benefit from investment in improving the availability of high quality habitats than controlling squirrel populations or increased investment in supplementary feeding.

Assessing the potential for Grey Squirrels Sciurus carolinensis to compete with birds at supplementary feeding stations

The data indicate that Grey Squirrels may eventually alter the net effect of supplementary feeding on bird populations across the European continent; increased use of squirrel-proof feeders may help to minimize such effects.

Potential impact of grey squirrels Sciurus carolinensis on woodland bird populations in England

The results indicate that grey squirrels are very unlikely to have driven observed declines of woodland birds in recent years, although the number of associations, positive as well as negative, betweengrey squirrels and woodland birds is greater than expected by chance.

Provision of supplementary food for wild birds may increase the risk of local nest predation

As supplementary feeding is becoming increasingly common during the breeding season in suburban habitats, it is suggested that providing point attractants to nest predators at this time may have previously unconsidered consequences for the breeding success of urban birds.

Squirrels in suburbia: influence of urbanisation on the occurrence and distribution of a common exotic mammal

The potential for grey squirrels to connect city dwellers with nature appears to be highest in urban locations that have considerable capacity to support native biodiversity, which challenges arguments that urbanisation favours exotic species.

Changes in the impact and control of an invasive alien: the grey squirrel (Sciurus carolinensis) in Great Britain, as determined from regional surveys.

Survey results support suggestions that grey squirrels in mainland Europe should be eradicated to prevent future population expansion and any accompanying impacts on commercial timber crops.

Wild Bird Feeding in an Urban Area: Intensity, Economics and Numbers of Individuals Supported

Abstract. Feeding wild bird is popular in domestic gardens across the world, with around half of households in the UK, North America and Australia doing so. Nevertheless, there is surprisingly

Birds breeding in British gardens: an underestimated population?

The number of birds nesting in built-up areas is substantially higher than previously estimated for 13 of the 21 species, and for some of the commonest British birds this has led in the past to significant underestimation of the total British population.

Foraging of Gray Squirrels on an Urban‐Rural Gradient: Use of the Gud to Assess Anthropogenic Impact

It is argued that the GUD represents a valuable metric with utility for measuring the separate and combined impact of anthropogenic actions at the individual and population levels.

A grey future for Europe: Sciurus carolinensis is replacing native red squirrels in Italy

Grey squirrel adapt to climate and habitats in both North and South Europe, causing extinction of the native red squirrel, was slow in the first 20 years, but doubled in the successive two decades, and spread was slower than in Ireland and England.
