Redstart
A summer visitor to the UK, the red-tailed redstart is a robin-sized bird that can be spotted in woodlands, parks and hedgerows, mainly in the north and west of the UK.
Redwing
The redwing is a winter visitor, enjoying the feast of seasonal berries the UK's hedgerows, gardens and parks have to offer. Look out for the distinctive orangey-red patches under its wings.
Reed bunting
A streaky brown bird, the reed bunting can be found in wetlands, reedbeds and on farmland across the UK. Males sport black heads and a white 'moustache'.
Reed sweet-grass
Reed sweet-grass is a towering grass with large, loose flower heads that can be found on marshy ground near rivers, streams and ponds. It can become invasive, but does shelter various aquatic creatures.
Reed warbler
Listen out for the 'chattering' song of the reed warbler, while wandering the UK's lowland wetlands in summer. A small, brown bird, they are quite hard to see.
Rhinoceros beetle
The rhinoceros beetle lives up to its name by sporting a distinctive 'horn' on the males' head. This glossy, blue-black beetle can be found in woods, parks and hedgerows, and depends on dead wood.
Rhododendron leafhopper
An introduced species, the Rhododendron leafhopper is a striking mix of green and red, with a black stripe across its face. It can be found feeding on Rhododendrons (also introduced) in Southern England.
Ribwort plantain
The brown, oval flower heads of ribwort plantain balance on top of thin, wiry stems; the resulting seed heads provide food for birds in winter. Look for this 'weed' in lawns, fields and grasslands.
Ring ouzel
The blackbird of the mountains, ring ouzels can be found breeding on upland moors and rocky crags in summer.
Ring-necked parakeet
The bright green ring-necked parakeet is an escapee and our only naturalised parrot; its success is likely due to warmer winters. It can be seen in the South East.
Ringed plover
The ringed plover is a small wader that nests around the coast, flooded gravel pits and reservoirs. It is similar to the little ringed plover, but is a little larger, has an orange bill and legs, and doesn't have a yellow ring around its eye.
Ringlet
The ringlet gets its name from the small rings on the undersides of its wings. These rings show variation in the different forms of this species, even elongating into a teardrop shape.
