More than 70 million birds have disappeared from Britain's gardens over the last 50 years, reveals shock new research.
The UK is home to 73 million fewer of our feathered friends today than it was in 1970, according to a study by the British Trust for Ornithology (BTO).
Almost 30 million house sparrows, 20 million starlings, four million skylarks, two million blackbirds and one million chaffinches have vanished from the UK in just five decades, scientists found by comparing the results of BTO-led surveys from the last 50 years.
