I continue my ecological survey of the fields south of Addenbrookes Hospital around the Nine Wells nature reserve.The field on the hospital side of the cycle path is wonderfully wild at the moment – this morning I heard 3 corn buntings there (right) and saw 2 (possibly 3) pairs of reed buntings. A yellowhammer was also singing and several skylarks.
The field on the other side of the cycle path had been earmarked by South Cambridgeshire District Council for further development. However, the conservatives suffered a shock defeat in the recent local elections. The liberal democrats, who now have overall control of the council, had campaigned vigorously against the proposed development. Let’s hope they now throw it out – I am trying to clarify the position. In case they need reminding, you can write to local councillors.
My 2017 survey of the area – which you can download below – showed that the area remains extremely valuable for farmland birds of high conservation concern, with exceptional numbers of grey partridge in the autumn, as well as good numbers of skylark, linnet, yellowhammer and corn bunting.
‘The square km south of Addenbrookes has this year supported a grey partridge population of at least 11 spring pairs/km2 and 85 birds/km2 in autumn. The arable farms typical of Cambridgeshire support between 0 and 5 pairs/km2 and 0–20 birds/km2 in the autumn.’
Corn buntings also did particularly well last year, with 8 pairs. This is an important population – there are just 11,000 birds in the UK and its recent extinction in Ireland risks being repeated in large parts of Britain if its breeding sites are not protected. The RSPB’s nearby Hope Farm had 2 pairs in 2016 in 1.8km2.
In addition, the site supports a thriving population of water voles, both in the start of Hobsons Brook, and in the ditch that runs alongside the cycle path.
