Reed Bunting

Reed Bunting

Emberiza schoeniclus
Reed Bunting, Amy Lewis

Introduction

Not just a bird of reedbeds, this common species is widely distributed across much of Britain & Ireland throughout the year. It is absent only from the highest upland areas.

The male Reed Bunting has a striking black head with a white moustachial stripe; the female has a browner head, but the moustachial stripe is still visible. When perched, both sexes flirt their tail sideways, showing white outer feathers. The male's buzzing call is distinctive.

In winter, the Reed Bunting often joins other finches and buntings to feed in arable landscapes. At the end of the 20th century, BTO research attributed declines in these species to intensive agriculture reducing food availability over the winter months. This issue has been, to some extent, addressed through agri-environment schemes, and there has been a gradual overall increase in the UK population since the late-1990s. However, the picture is mixed with a significant decline in South-east England.

Causes of Change and Solutions

Causes of change

Detailed demographic analyses suggest that the decline was driven by decreasing survival rates and that a subsequent population recovery may have been prevented by increased nest losses.

Further information on causes of change

The early increase in the CBC index was associated with a gradual spread into drier habitats, especially farmland, and it is likely that the subsequent decline was related to agricultural intensification. Detailed demographic analyses suggest that the decline was driven by decreasing survival rates and that a subsequent population recovery may have been prevented by increased nest losses (Peach et al. 1999). This is supported by a steep decline in CES productivity and by a major increase in failure rates at the egg stage, and a consequent fall in the number of fledglings per breeding attempt. Farmland densities are four times higher in oilseed rape than in cereals or setaside and this crop is crucial in reducing the dependency of the species on wetlands (Gruar et al. 2006).

Information about conservation actions

Like the related Yellowhammer, the research suggests that the main driver of the decline may have been reduced survival and therefore conservation actions to ensure sufficient food is available during winter will be needed to help reverse the decline. However, there is also evidence that increased nest losses may be preventing recovery and so this also needs to be addressed.

During winter, similar conservation actions to those proposed for Yellowhammer and other seed-eating birds are likely to also benefit the Reed Bunting. These include the direct provision of supplementary food, the retention of stubble fields, the planting of wild bird seed or game cover, reducing herbicide and pesticide use, and the provision of semi-natural habitats, e.g. through the provision of buffer strips, set-aside and conservation headlands, and through less intensive farmland management practices.

For Reed Buntings nesting in wetlands, a Swiss study suggested that, in order to reduce the probability of nest predation, wetland reserve management should aim to create larger wetlands and large dense reed patches rather than fragmented habitat (Pasinelli & Schlegg 2006). Away from wetlands, nesting densities in farmland are four times higher in oilseed rape than in cereals or set-aside and therefore this crop is crucial in reducing the dependency of the species on wetlands (Gruar et al. 2006).

Published: 2022

The latest review of the conservation status of birds in Wales. The report assessed all 220 bird species which regularly occur in Wales. There are now 60 species of bird on the Red List, with 91 on the Amber List and just 69 - less than a third of the total number of species - on the Green List.
