Did You Spot the Animals?

Bechstein's Bat

Hidden within our picture books are lots of animals that are currently on the UK’s Red, Amber and Green lists.

Future generations must fall in love with nature before it’s lost forever.

The UK is rapidly losing too many native species, most of which need woodlands to thrive.

Their decline is due to habitat loss and climate change.

Green List Animals

These are some of the most common animals found in the UK.

Bank Vole

Bank Vole

Lifespan: 4–18 months (rarely up to 2 years)

Status: Widespread and common across the UK

Physical Appearance
  • Fur: Rich reddish-brown back with lighter greyish underparts

  • Face: Blunt nose, small eyes, and whiskers
  •  

  • Habitat & Distribution

    • UK Distribution: Common throughout mainland Britain, absent only from some islands (e.g. Ireland, where the species is not native)
    • Preferred habitat:
      • Woodlands, hedgerows, and scrubland
      • Gardens and parks with good ground cover
      • Bank voles particularly like areas with dense vegetation and fallen logs for shelter
    • Plant-based foods: Leaves, fruits, nuts, seeds, buds, grasses, and roots
    • Animal foods: Insects, larvae, and occasionally small snails
    • Special favourite: Hazelnuts — they gnaw a neat round hole in the shell to eat the kernel inside (unlike wood mice, which leave rough-edged holes)
  • Activity: Active both day and night, but most lively at dawn and dusk
  • Movements: Create runways (small tracks) through vegetation, linking feeding and nesting sites
  • Social structure: Territorial — individuals maintain small ranges but can overlap
  • Winter: Do not hibernate; stay active year-round, feeding on stored food when possible
  • Breeding season: March to October
  • Litters: Up to 4–5 per year, with 3–7 young per litter
  • Gestation: 18–23 days
  • Development: Young are weaned after 3 weeks and become sexually mature in just a few months
  • Population booms: Can increase rapidly in good years, supporting predators like owls, stoats, and foxes
  • Conservation status: Least Concern — very common across the UK and Europe
  • Main threats: Predation and harsh winters, but populations are usually stable
  • Important prey species that help sustain many predators in woodland food chains
  • They are excellent climbers, often seen foraging in low bushes or brambles.
  • Bank voles are sometimes called the “red vole” because of their reddish-brown fur.
  • Their neat hazelnut holes are a good way to identify their presence in the woods.
  • Though small, they are very bold and often dart across woodland paths in daylight.
  • They play a key role in forest regeneration by spreading seeds and nuts.
  • Birds of prey: owls, kestrels, buzzards
  • Mammals: foxes, stoats, weasels, cats
  • Snakes: adders and grass snakes

Bees

Scientific Name: Apis mellifera (Western honeybee)

Native Status: Not truly native (originally from Europe, Africa, and Asia), but widely established and managed in the UK.

Population: Mostly found in managed hives; very few truly wild colonies remain.

Habitat: Gardens, woodlands, meadows, and urban areas.

Role: Essential for pollinating wildflowers and food crops, contributing significantly to UK agriculture.

Physical Characteristics
  • Size: 12–15 mm long
  • Colour: Golden-brown with black stripes
  • Wingspan: About 25 mm
  • Body Features:
    • Head: Large compound eyes, two antennae, strong mandibles
    • Thorax: Contains powerful flight muscles
    • Abdomen: Houses the stinger (females only)
  1. Queen Be
    The only fertile female in the colony.
    Lives up to 5 years.
    Lays up to 2,000 eggs per day during peak season.
    Secretes pheromones to regulate hive behaviour.

  2. Worker Bees (Sterile females)
    Perform all hive duties:
    – Nursing larvae
    – Foraging for nectar and pollen
    – Cleaning and defending the hive
    Lifespan:
    Summer workers: 5–6 weeks
    Winter workers: Several months

  3. Drones (Males)
    Their sole purpose is to mate with a queen.
    Have no stinger.
    Die after mating or are expelled from the hive in autumn.
  • Primary Food: Nectar and pollen from flowers.
  • Honey Production:
    • Nectar is collected and stored in wax honeycombs.
    • Worker bees use enzymes to break down nectar into simple sugars.
    • Water is evaporated from the nectar to create honey, which is stored as a food source.
  •  
  • Crops Pollinated:
    • Honeybees are mostly kept in managed hives and are likely responsible for pollinating between 5-15% of the UK’s insect-pollinated crops. Such as Apples, pears, strawberries, raspberries, oilseed rape, clover, and beans. That leaves 85-95% of the UK’s insect-pollinated crops relying on wild pollinators.
    • Many species of bee, wasp, moth, butterfly, hoverfly, fly and beetle provide an essential service in the UK (and globally) pollinating £690 million worth of crops annually.
  • Wildflower Pollination:
    • Supports biodiversity by fertilising native plants. They are also vital for the survival of other wild plants that support so much of the UK wildlife.

Three bumblebee species have become extinct in recent decades. The recent European Red List for Bees reports that almost one in ten species of wild bee face extinction, and over the past 50 years, half the bee, butterfly and moth species studied in the 2013 State of Nature Report have declined. This is due to:

    1. Habitat Loss
      • Urbanisation and intensive farming reduce flower-rich areas.
    2. Pesticides & Chemicals
      • Neonicotinoids (now banned in the UK except for emergency use) harm bees’ nervous systems.
    3. Climate Change
      • Alters flower blooming times, affecting food availability.
      • Causes extreme weather events that disrupt colonies.
    4. Pests & Diseases
      • Varroa destructor (Varroa mite): A deadly parasite that weakens bees and spreads viruses.
      • Nosema: A fungal disease affecting digestion.
      • American Foulbrood & European Foulbrood: Bacterial infections that devastate colonies.
    5. Colony Collapse Disorder (CCD)
      • Although rare in the UK, colonies sometimes collapse due to a combination of stress factors.
  • Bans on Harmful Pesticides:
    • The UK has restricted neonicotinoids, which are highly toxic to bees.
  • Government & NGO Initiatives:
    • The National Pollinator Strategy encourages habitat creation.
    • Organizations like The British Beekeepers Association (BBKA) support bee health.
  • Wildflower Planting:
    • Farmers and local councils create bee-friendly wildflower meadows.
  • Sustainable Beekeeping:
    • The UK has around 44,000 beekeepers, most of whom are hobbyists.
    • Ethical hive management ensures colony health.
  • A single honeybee visits up to 1,500 flowers per day.
  • Bees must fly 55,000 miles to produce one pound of honey.
  • UK honeybees communicate using the waggle dance to show others where to find food.
  • Honey has antibacterial properties and was used in WWI to treat wounds.
  • Each hive can produce 30–40 lbs of honey per year, depending on conditions.

The Uk Honey is not currently placed on the red list, however, there are several bumblebee species (6) in the UK that are on the Red List due to population declines caused by habitat loss, climate change, and pesticide use.

Weight: 16–30 kg

Lifespan: 0–15 years in the wild, though they can live up to 24 years in captivity

Physical Characteristics
  • Fur:
    • Thick, water-resistant brown fur
    • Dense undercoat for insulation
  • Tail:
    • Flat, leathery tail that acts like a rudder in the water and a tool for communication (slapping on water)
  • Teeth:
    • Orange incisors that grow constantly and need to be worn down by gnawing
  • Webbed Feet: Adapted for swimming
  • Eyes and Ears: Positioned higher on the head to allow them to see and hear above water while remaining mostly submerged
  1. Native Range:
    • North America: Castor canadensis is found throughout North America
    • Europe and Asia: Castor fiber is found across parts of Europe, Russia, and parts of Asia
  2. Preferred Habitat:
    • Freshwater rivers, streams, lakes, and wetlands
    • Forests near water
    • Beaver ponds created by their dam-building
  • Semi-Aquatic: Spend much of their time in water but build dens and lodges on land
  • Nocturnal: Beavers are typically most active during dusk and night
  • Social Structure:
    • Live in family groups, usually consisting of parents, last year’s offspring, and younger kits
    • Each family maintains a territory defended against other beavers
  • Communication:
    • Tail slapping on water as a warning signal
    • Wood gnawing sounds to communicate with others
  • Main Foods:
    • Tree bark, leaves, roots, and aquatic plants
    • Favourite trees: Willows, aspens, birches, and poplars
    • In the winter, they feed on woody plants stored underwater
  • Foraging Behaviour:
    • Use their sharp teeth to gnaw down trees to build dams and lodges
    • Cut branches and store them near the water for winter feeding
  • Dams:
    • Beavers are known for their remarkable ability to build dams using branches, mud, and stones.
    • The purpose of a dam is to raise water levels so they can access food during winter, create a safe environment for their lodge, and protect themselves from predators
  • Lodges:
    • Built from branches and mud, the lodge is an entrance submerged under water, providing safety from land predators
    • Multiple chambers are created inside for nesting, living, and storing food
  • Canals:
    • Beavers often dig canals to transport logs and access new food sources
  • Mating Season: December to February
  • Gestation: About 105–107 days
  • Kits:
    • Usually 2–4 kits per litter
    • Born fully furred, with their eyes open and able to swim almost immediately
  • Parental Care:
    • Both parents help care for the kits
    • Kits stay with the family until they are 2 years old, learning to build their own lodges
  • Conservation Status:
    • Least Concern globally, though they were nearly wiped out in the 19th and early 20th centuries due to hunting for fur and habitat loss
  • Main Threats:
    • Habitat loss due to land development, river drainage, and deforestation
    • Conflicts with human activities (flooding of roads, farmland, and forests by dams)
  • Positive Impact:
    • Beavers are considered a keystone species, meaning they greatly influence the environment around them by creating wetlands, improving water quality, and providing habitat for other species
  • Reintroduction Efforts:
    • Beavers were reintroduced to the UK starting in the early 2000s (primarily in Scotland and Wales) after being hunted to extinction around 400 years ago
    • Protected species in the UK, with active monitoring of reintroduced populations
  • Eco-engineers: Beavers’ dams can help reduce flooding, increase biodiversity, and improve water quality by trapping sediments and filtering pollutants.
  • Amazing Builders: A beaver can build a dam up to 1,200 feet long in some cases!
  • Incredible Memory: Beavers can remember where they have stored food, even in winter!
  • Beaver Lodges Are Cozy: The lodge’s temperature can stay around 0°C in winter, much warmer than the outside temperature.
  • Tail Slap Warning: When threatened, beavers make a loud tail slap to alert others of danger.
Cobweb_Beetle-

Cobweb Beetle

Family: Dermestidae (the carpet beetle family)

Size: Length: 3–5 mm long (very tiny!)

Physical Characteristics
  • Shape: Oval, compact body with short legs
  • Colour: Dark brown to black, often covered with fine hairs that give them a dusty look

Where found:

    • Across much of Europe, including the UK
    • Often found in old buildings, barns, outhouses, or sheds
    • Preferred habitat:
      • Places with cobwebs, dust, or animal remains
      • Also found in bird nests or old wasp nests
      • Secretive: Usually live in dark, hidden corners, making them easy to miss
  • Slow-moving and often remain hidden in crevices
  • Do not spin webs — they just live in spider webs, feeding on leftovers
  • Can survive in very dusty, neglected corners of buildings where other food is scarce
  • Main food sources:
    • Dead insects caught in spider webs
    • Feathers, fur, and other animal remains
    • Dried organic debris
  • Ecological role:
    • Act as nature’s recyclers, cleaning up waste and returning nutrients to the ecosystem
  • Eggs: Laid in sheltered spots with plenty of food
  • Larvae:
    • Fuzzy, hairy little grubs that also eat organic remains
    • Can survive long periods with little food
  • Adults: Emerge after pupation and continue scavenging
  • Life span: A few months to a year, depending on conditions
  • Not endangered — they are relatively widespread but often overlooked
  • Because they thrive in old, undisturbed places, they can be less common in modern, well-cleaned homes and buildings
  • In some cases, they can be considered a minor pest in natural history collections or stored animal materials (since they eat feathers, fur, etc.)
  • They’re called “cobweb beetles” because they live in spider webs, not because they make them.
  • They are part of the Dermestid beetle group, which includes species used in museums to clean skeletons of flesh!
  • Tiny recyclers: Their whole life revolves around cleaning up what’s left behind in nature.
  • You’ve probably been near one without even realising it — they’re so small and shy!

Red List Animals

These are some of the most endangered animals in the UK which are close to extinction, if we don’t do anything to protect them.

Since we put this page together some of the animals listed within our books has sadly been moved from the Green List to the Red List. Making Nature Conservation even more crucial for children to learn about.
