Raccoons are excellent climbers, and they spend much of their lives in trees even though they find most of their food on the ground. For a raccoon, a big old tree is a house, a hiding place and a pantry at once.
How Raccoons Climb Up And Come Down Head First
A raccoon’s front paws work almost like hands. They have five long, nimble fingers and sharp, curved claws that hook into bark. Raccoons can also twist their forearms to turn their palms upward, more than related animals such as the raccoon dog and red panda can.1J-STAGE. Mobility of the forearm in the raccoon (Procyon lotor), raccoon dog (Nyctereutes procyonoides) and red panda (Ailurus fulgens) That lets them wrap a paw around a trunk or branch and grip it from different angles.
A climb starts with the raccoon hugging the trunk, pulling with its front claws and pushing with its back feet. It moves in short bursts rather than gliding smoothly the way a squirrel does. Thick, rough bark is easy going. Claws do most of the work there, so a raccoon on a rough-barked oak or a wooden fence post moves with confidence. On a painted metal pole or slick siding, the claws have nothing to hook into. The raccoon has to press its body and limbs against the surface, which is slower and less secure.
Raccoons can come down a tree head first by turning their back feet around so the claws point backward and hold on.2Skedaddle Humane Wildlife Control. How do raccoons get on your roof? In studies of climbing mammals their size, though, raccoons came down tail first more often than other meat-eating climbers.3PubMed Central. Kinematics and morphological correlates of descent strategies in arboreal mammals suggest early upright postures in euprimates
Squirrels leap from branch to branch far more often than raccoons do. Raccoons are heavier, so they favor thick trunks and limbs, and they rely more on grip and strength than on speed. A raccoon keeps its weight close to the trunk, spread over several grip points, rather than perching on thin twigs. That is why you often see one tucked into a fork or sitting on a broad limb, and why thin outer branches are poor places to look.
Young raccoons are not born skilled climbers and have to practise. In early summer, mothers coax kits up and down trunks. Falls are common while the kits learn and are usually not serious.
Why Raccoons Climb, Safety, Sleep And Raising Young
Climbing is a vital skill for escaping predators such as wolves that can’t climb.4Animals. Watch: Mother Raccoon Helps Baby Learn to Climb Tree Raccoons will sometimes climb very high to get away from predators at night.5Westchester Wildlife. Can Raccoons Live In Trees In Your Yard?
A frightened raccoon often climbs quickly, then stops in a fork or on a limb and looks down at whatever scared it. It may stay there a long time, often until the dog, person or noise that sent it up has gone away. If a dog is involved, the kind thing is to bring the dog inside and leave the raccoon alone so it can come down and leave on its own. Chasing or poking at it only keeps it stuck longer.
Tree cavities are critical for raccoons, giving them a safe place to sleep and raise their young.6Animals. Watch: Mother Raccoon Helps Baby Learn to Climb Tree A tree raccoons use as a home is often called a den tree. Raccoons pick den trees that are bigger than average, averaging about 78 cm (roughly 31 inches) across at chest height versus about 50 cm for trees overall in one forest.7Natural Resources. Raccoon Use of Den Trees and Plant Associations in Western Mesophytic Forests: Tree Attributes and Availability or Landscape Heterogeneity? Beech trees made up under 9% of trees there but 65% of the dens chosen.8Natural Resources. Raccoon Use of Den Trees and Plant Associations in Western Mesophytic Forests: Tree Attributes and Availability or Landscape Heterogeneity? In a pine-dominated area, raccoons rested in hardwoods far more than pines, and bigger trees were used more.9CrossRef / Restoration Ecology. Hardwood management and restoration of longleaf pine ecosystems may affect raccoon daytime resting sites
Older hardwoods are more likely to develop hollows as limbs break and rot, and those hollows protect against weather and predators. Removing every old tree can push raccoons to look for attics and chimneys instead.
Clues that a tree may be a den include a hole wider than a fist high on the trunk, with fresh claw scratches and worn bark around it, though other animals use tree holes too. In spring and early summer you may also hear kits.
A mother usually gives birth in spring in a sheltered spot such as a tree hollow, and the kits stay there for their first weeks. They are blind and helpless at first, so a protected cavity matters a great deal for their survival. Mothers often move young to other dens as they grow, so a den tree may be used for only part of a season. A mother with young nearby is likely to be defensive, so give a suspected den plenty of room.
Raccoons are mostly active at night and rest by day. They may sleep in a hollow, on a broad limb, or in a squirrel nest, and they often move between several resting spots over a week. Seeing one asleep in a tree by day is normal and not a sign of illness on its own.
Climbing For Food
Raccoons eat almost anything, including fruit, nuts, grains, insects, crayfish, rodents, birds, eggs, fish and dead animals.10CT.gov. Raccoon Nuts they favor include acorns, hickory nuts and beechnuts.11CT.gov. Raccoon Tree and vine fruits on their menu include persimmon, black cherry, wild plum, grape, apple and serviceberry.12South Carolina Department of Natural Resources. Raccoon management guide Fruit and nut trees in a yard can draw raccoons up into the branches when crops ripen.
Climbing makes sense when the food is still on the tree and out of reach from the ground, as with ripe fruit, bird eggs or nuts that haven’t fallen. Once the same food drops, a raccoon will usually pick it up from the ground, which takes less effort and carries fewer risks. Many nuts are eaten after they fall, and raccoons still spend much of their foraging time on the ground and near water. Climbing for food is seasonal, peaking with ripe fruit. A raccoon in a fruit tree is after a crop, and the same animal may ignore the tree when nothing is left in it.
In a yard, tree feeding shows up as half-eaten fruit and pits under the tree in the morning, small broken branches from a heavy animal, and bird feeders hung from limbs raided overnight. Squirrels and birds also eat fruit, so damage alone doesn’t prove a raccoon did it. Paw prints in soft ground or mud under the tree are a stronger clue. To reduce the draw, pick ripe fruit promptly and clear windfalls, bring feeders in at night, and secure trash so the yard is less worth visiting.
Can Raccoons Use Trees To Get On Your Roof
Raccoons can climb a tree and jump to a fence, or jump directly onto a roof if the tree is close.13Wildlife Control Education. Do Raccoons Climb Trees? Why and How They Do It On bungalows or low garage roofs, wooden structures around the house can serve as routes to the roof.14Skedaddle Humane Wildlife Control. How do raccoons get on your roof?
The route usually goes like this: the raccoon climbs the trunk and moves out along a limb that reaches toward the house. From the end of the limb it steps or jumps to the roof edge, gutter or a nearby fence. The shorter the gap, the easier the move, so branches that touch or overhang the roof make an easy crossing. A raccoon that has found the route once is likely to use it again.
On the roof, a raccoon finds chimneys, vents, loose soffits and gaps near the eaves that can lead into attics. Attics are warm, dry and dark, so they can look like a good substitute for a tree hollow, especially to a mother searching for a den in spring. Signs of a visitor include thumps or scratching overhead at night, muddy paw prints on siding or gutters, torn shingles, vents or soffits, and bent downspouts or trellises.
To make the route harder, cut limbs so there is a clear gap of several feet from the roof, and cap chimneys and cover vents with sturdy metal mesh. Raccoons can also shimmy up corners and downspouts, so removing trees alone may not stop a determined one. Check that no one is inside before sealing an opening, especially in spring when kits are present.
Raccoons And Bird Nests In Your Trees
With strong climbing, swimming and digging skills, raccoons readily reach the eggs and chicks of many bird species.15ARPHA Conference Abstracts. Prioritizing bird conservation under northern raccoon predation: assessing species vulnerability from nesting success In Illinois, songbirds whose nests raccoons can reach declined by about 10% per survey route while species out of reach rose about 15%.16Conservation Biology. Nest Predation and Population Declines in Illinois Songbirds: a Case for Mesopredator Effects The reachable species lost far more nests to predators.17Conservation Biology. Nest Predation and Population Declines in Illinois Songbirds: a Case for Mesopredator Effects
A raided nest is often found empty, with eggs or chicks gone and the nest damaged or pulled apart. Raccoons usually hunt at night, so the loss is generally discovered the next morning, when the parents are circling or calling. Snakes, cats and crows also raid nests, so an empty nest doesn’t prove a raccoon did it.
Height alone doesn’t make a nest safe. Nests on thin outer branches may be harder for a heavy animal to reach, while nests in forks or close to the trunk are easier. Boxes on trees or fences are especially easy, because the raccoon can walk right up to them.
Baffles that block climbing mammals are one common way to predator-proof nest boxes.18Birds. Predator-Proofing Avian Nestboxes: A Review of Interventions, Opportunities, and Challenges Combine a baffle with mounting the box on a smooth pole away from branches. Use a cone or tube baffle on the pole below the box, place the pole where no branch or fence lets a raccoon jump across, and keep the box high enough to clear the baffle and away from the trunk.
The box itself matters too. Deeper boxes keep eggs out of paw reach, and thicker front panels or entrance guards stop arms reaching in. Avoid perches, which give a raccoon something to grip.
Health Risks Near Raccoon Trees
Raccoons reuse the same toilet spots, called latrines. Most latrines sit on logs or at the base of large trees.19The American Midland Naturalist. Raccoon Latrine Structure and Its Potential Role in Transmission of Baylisascaris procyonis to Vertebrates They hold infective eggs of a raccoon roundworm that harms many mammals and birds.20PubMed. Implications of raccoon latrines in the epizootiology of baylisascariasis Mice and birds routinely visit latrines to pick seeds out of droppings and can be infected there.21PubMed. Implications of raccoon latrines in the epizootiology of baylisascariasis The roundworm can also seriously sicken people, especially young children, who swallow eggs.
Young children are at special risk because they put hands and objects in their mouths and play in the dirt. The eggs aren’t dangerous just from being nearby; the risk comes from contact with the droppings or the soil around them, followed by swallowing.
Roundworm eggs are hardy and can survive in soil and droppings for a long time. A latrine that looks old and dried out may still hold eggs that can infect, so handle a site with care even if no raccoon has been seen there lately.
To clean a latrine safely, wear gloves and a mask and avoid stirring up dust. Bag the droppings and put them in the trash. Use boiling water or flame on hard surfaces, since ordinary disinfectants don’t kill the eggs, and wash your hands well afterward.
Teach children not to play where raccoon droppings pile up, and check under decks and around big tree trunks. Keep pets away from those spots and ask a vet about deworming.
