Greenfinches flock together to feed at this time of year, as we watched at Old Moor RSPB site near Barnsley yesterday, where we went to replenish birdfood stocks. Following a big decline in the 1970’s and 80’s, thought to be due to loss of seeds on farmland, a further decrease is linked to a parasitic disease that affects their ability to feed. So, while garden feeders are very important for these finches, which can manage big and small seeds alike, if you don’t keep feeders well cleaned, you could be adding to the spread of the disease. At Old Moor they were feeding quite aggressively, hence all the comings and goings in the photographs- in flight their beautiful colours stand out. Conditions: A largely sunny, still day. Temperature: Max 14- Min 9c.
