Two birds which are icons of Christmas are tumbling catastrophically in numbers. The stars of the chorus of The Twelve Days of Christmas, the turtle dove and the grey partridge (the one that's in-a-pear-tree) are disappearing from many parts of Britain.
Once widespread in the south, the turtle dove population, currently estimated at 14,000 pairs, is now balancing on a knife-edge in Britain, with nearly 60 per cent lost just in the five years to 2010, the Royal Society for the Protection of Birds said.
The British grey partridge population is estimated to be around 43,000 pairs, but this too has fallen, by 30 per cent over the same period.
Losing six out of 10 turtle doves and three out of 10 grey partridges in five years was nothing short of an unsustainable wildlife disaster, said the society's conservation scientist, Dr Mark Eaton.
"The turtle dove is in a great degree of danger. If this trend were to continue we could be down to fewer than 1000 pairs by the middle of the next decade, with complete extinction a real possibility."
