Long-tailed duck
This dainty seaduck is a winter visitor to our coasts, particularly in northern and eastern Scotland.
Long-tailed tit
Living up to its name, the long-tailed tit can be easily recognised by its long tail. It is a small, pretty, pink, black and white bird that can be seen in woodlands, gardens and parks.
Long-winged conehead
The long-winged conehead is so-named for the angled shape of its head. It can be found in grasslands, heaths and woodland rides throughout summer.
Lords-and-ladies
Look for the unusual flowers of lords-and-ladies in spring woodlands: a pale green sheath surrounds a spike of tiny, yellow flowers. This spike eventually forms a familiar, short stalk of striking red berries.
Lugworm
Have you ever seen those worm-like mounds on beaches? Those are a sign of lugworms! The worms themselves are very rarely seen except by fishermen who dig them up for bait.
Lumpsucker
This funny-looking fish certainly won't be winning any beauty pageants, but it's a real contender for Father of the Year!
Mackerel
Mackerel are a sign of summer's arrival, when they appear inshore in huge numbers all around the UK. As well as being a sustainable seafood choice, they are an important food source for many of our marine predators.
Magpie
"One for sorrow, two for joy…" is a popular rhyme associated with the magpie - a bird of much myth and legend. An unmistakeable member of the crow family, it can be seen almost anywhere.
Magpie moth
The magpie is a distinctive moth with striking black and yellow spots on white wings. It is a frequent garden visitor, but also likes woodland, scrub and heathland.
Maidenhair spleenwort
A small, tufted fern, maidenhair spleenwort can be found growing out of crevices between rocks, in walls and on mossy branches across the UK.
Male-fern
A classic fern of woodlands across the UK, the male-fern is also a great addition to any garden. It grows impressive stands from underground rhizomes, dying back in autumn.
Mallard
The much-loved mallard is our most familiar duck, found across town and country. If your feeding the ducks please don't feed them bread - it's not good for them! Instead, they love eating sweetcorn, lettuce, oats and seeds.
