At long last a few Siskins have appeared at the nijer feeder but nothing like the numbers I have seen in previous winters.
On the subject of pigeon numbers/feed - at this time of the year, in this part of the world, they regularly feed on White Clover leaves - hence their occurrence on pastures. Winter numbers in Ceredigion have declined markedly since the introduction of Oil seed Rape crops into the arable areas of the UK.
