The Winter Bird Crops are going from strength to strength looking at the way the birds are rushing to get to them. Results from last winter’s surveys at the crops show an increase in bird numbers of almost 40% in density (birds per hectare), even when the number of fields and area planted did not increase from the previous year. Most encouragingly, the vast majority of birds feeding at the crops were the targeted species: farmland birds such as chaffinch, linnet, reed bunting, meadow pipit, goldfinch and starling.

The winter bird crops are crucial to keep hundreds of birds fed and alive throughout the winter, when there is not much food to be found in the fields or hedges. Many of the species benefiting from them are threatened right across their British and European ranges, and include local birds and migrants who come to spend winter here.

Farmland birds are in decline across Europe, the UK and Jersey, with some species having become locally extinct and many others considered threatened. One of main reasons of these declines is lack of food during winter which causes high levels of mortality. The so-called ‘Winter Bird Crops’ provide a source of food at this critical time, increasing the chances of survival of many threatened birds both local and migrants
Birds On The Edge works with Jersey’s potato farmers to provide winter bird crops for the longest time possible. A variety of crops are planted with staggered management regimes, ensuring that the crops do not disappear at once when the fields are planted with potatoes. The crops provide seeds and grains of various sizes, energy and nutritional values
In 2015 a total of 47 fields were planted to feed farmland birds during the 2015-16 winter. The fields were found at 12 different sites, and, combined, covered a total of 33.3 hectares (163 vergées)
The development of the crops and bird activity was monitored throughout the winter. A total of 46,155 records of birds of 54 species were collected over sixteen surveys, of which 40,949 (88.7%) were of target species (endangered farmland birds)
Of the ten most abundant species found at the crops, seven were farmland (target) species: chaffinch, linnet, starling, goldfinch, greenfinch, meadow pipit and reed bunting. A total of 14 target species was recorded at the sites. The most successful site had an average of 461 target birds per hectare
Net numbers increased by 13,874 birds compared to 2014-15 (54% increase) and by 33,177 compared to 2013-14 (534% increase)
The overall density of target birds increased by 39% from the previous winter (2014-15) and by 140% compared to the winter of 2013-14
The seed for the bird crops was purchased and provided thanks to the generosity of a private donor. It costs approximately £3,500 to plant the winter bird crops in Jersey
This year’s crops, which are already feeding birds in larger numbers than ever recorded, were paid for by the local charity Action For Wildlife and by the States of Jersey’s Countryside Enhancement Scheme
Our research proves just invaluable the crops are for these vulnerable species and we believe that continuing this scheme is paramount for their survival. As we begin to plan for next year’s crops with the farmers, Action For Wildlife has stepped up once again and donated £1000 towards the seed for next year’s crops. This will be added to a private donation of £200 we received in the autumn, as we close in our target of £3,500.
