Wryneck

Wryneck

Jynx torquilla
Wryneck, Liz Cutting

Introduction

This former breeder was once a common bird across much of central and southern England, favouring commons, heathland, orchards, parkland and larger gardens.

This small woodpecker, with its delicately-patterned plumage, is now only a very occasional breeder and typically only seen on passage during autumn and spring.

Causes of Change and Solutions

Causes of change

The decline and extinction of this species in the UK is believed to have been driven by a drop in food availability caused by a shortage of bare ground and short vegetation, although a number of other factors may have contributed including agricultural intensification, climate change, an increase in conifer plantations and the effects of pesticides (Balmer et al. 2013).

The risk of extinction for birds in Great Britain

Author: Stanbury, A., Brown, A., Eaton, M., Aebischer, N., Gillings, S., Hearn, R., Noble, D., Stroud, D. & Gregory, R.

Published: 2017

The UK has lost seven species of breeding birds in the last 200 years. Conservation efforts to prevent this from happening to other species, both in the UK and around the world, are guided by species’ priorities lists, which are often informed by data on range, population size and the degree of decline or increase in numbers. These are the sorts of data that BTO collects through its core surveys.
