The Population Status of Birds in Wales:
Population trend and distribution
Fairly numerous in the lowlands, patchier in distribution to the west and scarce in the uplands (Green 2002). The RWBS data for Wales is a little unclear showing both a 268.4% increase (the RSPB) and a 8.3% decrease (BTO). The BBS shows a significant decline of 30% in Wales 1994–2007.
General: woodland edge and scrub habitats are used, particularly where fruiting and flowering shrubs and trees are present. They will occupy most broadleaved woodland types, and thicket-stage conifer plantations may be of particular importance in the uplands.
especially in winter, may affect bullfinches breeding in woodland and scrub. A reduction in the amount of shrub and ground cover, eg through grazing and browsing pressure, may make nests more vulnerable to predation and affect food availability. A loss of complexity and density in the structure of woodland understorey vegetation could have multiple effects, including reducing food availability and the amount of available cover for nests such that the risk of nest predation increases (BTO 2008).
Nesting: nests are built in dense scrub or shrub layer trees, between 1 and 2 m above the ground.
Feeding: a variety of fruits and seeds are used throughout the autumn and early winter, especially ash and hawthorn. Stubbles and fallows are also exploited where they are close to dense cover. From late January, they take leaf and flower buds as they form. Invertebrates are important in the diet of the young.
A reduction in the availability of food,
particularly in neighbouring farmland,
Increase the extent or improve the quality of nest sites
Encourage the development of scrub, particularly at the woodland edge and along rides and glades.
Encourage a dense shrub layer by managing grazing and browsing, and planting and/or protecting suppressed plants.
Increase the extent or improve the quality of foraging habitat
Encourage the development of scrub, particularly at the woodland edge (which may require the management of grazing) and by planting favoured trees and shrubs, eg ash and hawthorn or larch in coniferous/mixed woodland.
Integrate woodland management with management of adjacent farmland to provide additional food resources, particularly in winter.
