The Royal Society for the Protection of Birds (RSPB) has released updated advice on safeguarding garden birds across the UK from highly infectious diseases, following alarming new research revealing a troubling drop in the numbers of some of Britain's most cherished garden species.
The RSPB has highlighted that a highly contagious illness known as trichomonosis is spreading rapidly and having a devastating impact on garden bird populations, particularly greenfinches, chaffinches, and potentially bullfinches as well.
The statistics paint a deeply concerning picture - the UK's greenfinch population has suffered a dramatic decline of more than 65% over the past 30 years.
