Springwatch, Autumnwatch and Winterwatch, sometimes known collectively as The Watches, are annual BBC television series which chart the fortunes of British wildlife during the changing of the seasons in the United Kingdom. The programmes are broadcast live from locations around the country in a primetime evening slot on BBC Two. They require a crew of 100 and over 50 cameras, making them the BBC's largest British outside broadcast events. Many of the cameras are hidden and operated remotely to record natural behaviour, for example, of birds in their nests and badgers outside their sett. Bank Holiday (the last Monday in May) and is broadcast four nights each week for three weeks. After the success of the first Springwatch in 2005, the BBC commissioned a one-off special, Autumnwatch, which became a full series in 2006. Winterwatch began in 2012, broadcast in January or February. The Springwatch brand has expanded to incorporate further TV spin-offs and specials, and also has a strong online presence. The BBC Springwatch website offers further video content and allows viewers and programme makers to interact through a message board, Flickr photography group, blogs and the @BBCSpringwatch and @BBCAutumnwatch Twitter accounts.

Bill Oddie, Kate Humble and Simon King were the presenting team until 2008. Oddie departed as a regular host at the beginning of 2009 (though not by his own choice), to be replaced by Chris Packham. Martin Hughes-Games, formerly a Springwatch producer, also joined the team in 2009. In September 2010, King left the presenting team to pursue other projects.

When Humble left after Springwatch 2012, Strachan became her permanent replacement. Strachan flies in from Cape Town South Africa to present the show.
