In the last decade Britain has suffered massive declines in many garden and farmland birds including the turtle dove and fieldfare.
But due to mild winters and conservation efforts other bird populations have grown, including the little egret and Mediterranean gull that have flown over the Channel.
Other more exotic birds like the hoope, fan-tailed warbler and black kite may arrive in the future as temperatures rise further.
Birds that have been re-introduced into the country have also thrived including the red kite, bittern and sea eagle.
The Royal Society for the Protection of Birds (RSPB) compiled the surveys of threatened birds since 2000 to give a snapshot of the winners and losers of the 21st centry so far.
The bird that has seen the larges overall increase in the past decade is the little egret, a small heron that is usually only found on the Continent.
The white bird was first noticed in Britain around the 1980s and it is thought it started nesting in the late 1990s. The wader is now found throughout the south of the country, with several hundred pairs.
The Mediterranean gull has also colonised the south of England.
Other birds that have done well, including the corncrake, sea eagle and bittern, were introduced or part of a huge conservation effort.
Mark Avery, conservation director of the RSPB, said bird life in Britain is changing.
“It has been a very busy decade in bird conservation with lots of competing priorities. There are birds which started the Noughties right on the brink, like the bittern, and a lot of people have put a lot of effort in to save them with some amazing results," he said.
“The return of the red kite, despite continued persecution, as well as the white tailed eagle and the corncrake to our countryside should serve as an inspiration for nature lovers. It proves that as well as pushing species to the edge by disregarding the wildlife we share our island with, we also hold the power to bring them back."
However he warned that the gains made from conservation could be lost by the decline in birds because of intensive farming, climate change and development. The marsh warbler, Arctic skua, fieldfare, turtle dove and golder oriole have seen the worse decline in the last decade.
“As well as the birds that are returning to the UK due to concerted conservation work, there are others that are declining for all kinds of reasons including global warming, changes in our countryside and habitat loss. So while we may celebrate every time we hear the booming call of the bittern, we know that there is a lot more work to be done in the years to come," he added.
