Royal Mail issued a set of 10 stamps on the theme of Migratory Birds on April 7, showcasing the diversity of spring and summer avian visitors to Britain.
About one in seven birds worldwide make annual, seasonal migrations along well-defined routes between their breeding and non-breeding grounds.
Often this involves travelling remarkable distances over land and sea.
Royal Mail’s set of eight stamps entitled Heroes of the Covid Pandemic, issued on March 23, features colourful designs by children aged between 7 and 14.
These were selected following a nationwide competition, launched last spring with the support of the Prime Minister, which attracted 606,049 entries, recognised by Guinness World Records as the most ever for a competition of its kind.
Entrants were invited to design postage stamps featuring their own heroes of the Covid-19 pandemic, which first hit the UK in the early months of 2020 and has brought death, illness and hardship to many.
