The linnet, with its forked tail and distinctive twittering flight call, is most likely to be seen near breckland. Particularly in areas such as NWT Weeting Heath NNR
Linnet populations have declined nationally over recent years and although numbers now appear stable in Norfolk it is not now as common as it once was. This may be due to the increase in sowing winter crops rather than spring sown crops which reduces the amount of winter stubble fields and therefore the availability of their food source. Other factors could be the increased use of fertilisers and herbicides. Habitat destruction such as the grubbing up of heathland, the removal of hedgerows or severe hedgerow cutting restricts the available nesting habitat.
The linnet is on the RSPB’s ‘red’ species list of conservation importance and is protected under the Wildlife and Countryside Act 1981.
A UK biodiversity action plan is currently being implemented for Norfolk; this will give advice to farmers encouraging them to provide adequate field margins, rotational set aside and retention of winter stubbles.
If you are lucky enough to have a hedgerow containing native species in your garden, it is best only cut every other year, this is because some species only flower on their second year growth. A bushy hedgerow will provide the Linnet with a suitable nesting habitat. Hedge trimming should not take place within the breeding season (March-September).
