Dartford Warbler
The Dartford warbler is dependent on mature, dry heath habitats in the UK, and particularly on gorse that is in good condition for surviving cold, harsh winters. It only eats insects and does not migrate for the winter, which means it is vulnerable to cold weather and prolonged snow cover. It is a ground-nesting bird, preferring to breed under the protective cover of dense heather or compact gorse.
