Greenfinch

Was pleased to see a greenfinch on the feeder this morning. A few years ago they were frequent visitors but their numbers have been decimated by an infection. This is caused by the protozoal parasite Trichomonas gallinae which progressively blocks the birds throat and prevents the birds from swallowing food. Birds with the disease can have fluffed-up plumage and show signs of lethargy, they may also drool saliva.
There is also a goldfinch on the lower perch.
