Springwatch episode 5 2021: Chris Packham and Michaela Strachan report live from Norfolk, where Springwatch’s remote cameras are capturing the wildlife dramas at Wild Ken Hill. Gillian Burke looks at some clever cuttlefish in Northern Ireland, and Iolo Williams heads up into the Scottish Highlands to spot some flamboyant avian show-offs.



 

 

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.

Springwatch begins on the Spring Bank Holiday 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.

Cuttlefish

Cuttlefish or cuttles are marine molluscs of the order Sepiida. They belong to the class Cephalopods, which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone, which is used for control of buoyancy.

Cuttlefish have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They generally range in size from 15 to 25 cm (6 to 10 in), with the largest species, Sepia apama, reaching 50 cm (20 in) in mantle length and over 10.5 kg (23 lb) in mass.

Cuttlefish eat small molluscs, crabs, shrimp, fish, octopus, worms, and other cuttlefish. Their predators include dolphins, sharks, fish, seals, seabirds, and other cuttlefish. The average life expectancy of a cuttlefish is about 1–2 years. Studies are said to indicate cuttlefish to be among the most intelligent invertebrates. Cuttlefish also have one of the largest brain-to-body size ratios of all invertebrates.

The “cuttle” in cuttlefish comes from the Old English name for the species, cudele, which may be cognate with the Old Norse koddi (cushion) and the Middle Low German Kudel (rag). The Greco-Roman world valued the cuttlefish as a source of the unique brown pigment the creature releases from its siphon when it is alarmed. The word for it in both Greek and Latin, sepia, now refers to the reddish-brown color sepia in English.
