Today a juvenile Greenfinch landed on our bird feeder, the first we have seen for some time. However it was obviously unwell. It tried to feed on seeds but did so without seeming to actually ingest any seeds and kept wiping its beak to clear it of seeds. It was lethargic, almost sleepy, and fluttered off into the undergrowth in the nearby garden. It returned some time later and went through the same actions.

I fear it may be suffering from  trichomonosis .

We used to get lots of Greenfinches, but this poor thing is the first we have seen in a long time.

Hope this is of interest.
