They’ll nap through the darkest part of the night and brightest part of the day. Rabbits rely on sunlight patterns to tell them when to sleep and awaken. They aren’t entirely dark during the day as the light gets in through the burrow holes. In the wild, rabbits spend most of their time in large warrens underground. Are cottontail rabbits nocturnal or diurnal? In winter, most subspecies of snowshoe hare develop pure white coats, which cottontail rabbits do not. Hares and rabbits can normally be distinguished by their ears – hares usually have far longer ones. Peter Cottontail is a young Easter Bunny who lives in April Valley where all the other Easter bunnies live and work, making Easter candy, sewing bonnets, and of course, decorating and delivering Easter eggs. Rabbits will still periodically get up to stretch and eat during the day and night, but you’ll notice them sleeping through most of the afternoon. This is a term that means they are most active around dawn and dusk. While wild rabbits sleep in the daytime, they’re careful to keep themselves hidden from predators. MK Thompson is assistant for education, volunteer programs and visitor information services for San Juan Mountains Association, a nonprofit dedicated to public land stewardship and education.Life in the Wild While a rabbit such as the Eastern cottontail still sleeps during the day, foraging at dawn and dusk, he’s more active at night in the summer, when food is more readily available. So if you still are uncertain about a particular animal’s sleeping habits, don’t lose sleep over it. Animals’ habits can vary depending on season and temperature. Other animals in this broad category include frogs, wolverines, coyotes, mountain goats and black bears.Īlso, the animals listed above are not necessarily confined to one category. While we tend to think of cats as nocturnal, they also see well during the day.īobcats, as well as cougars, lynx and house cats, might best be classified as cathemeral or arrhythmic. Some sources claim they are nocturnal in the summer but transition to diurnal in the winter. Most raptors (hawks, eagles, falcons), most lizards, bull snakes, squirrels (tassel-eared Aberts, chicory, ground), pikas, butterflies. If you see one out in the daytime, stay away from it and call the nearest state wildlife organization. Raccoons are so nocturnal that, if seen during the day, they are potentially rabid. Head out at dawn or dusk, and keep your eyes peeled for these animals.Ĭrepuscular mammals: cottontail rabbits, jackrabbits, ungulates (mule deer, elk, moose), bison, ferrets, mice and rats, beavers, river ottersĬrepuscular reptiles: rattlesnakes, gila monstersĬrepuscular birds: chimney swifts, many song birds, hummingbirdsĬrepuscular bugs: mosquitoes, many moths, many beetlesįoxes, most owls, nighthawks, skunks, bats, snowshoe hares, porcupine, badgers, milk snakes, raccoons. The list is long, so let’s stick with creatures found in the Four Corners. Climate also can dictate sleep patterns.Ĭrepuscular animals are found around the globe. Animals have adapted to either avoiding predation or enhancing hunting prowess. Some creatures are defined as “cathemeral” or “arrhythmic,” meaning they are sporadically active during any time of day.Īll of these sleep habits are behavioral adaptations. These sleep patterns that are dictated by light and dark generate a circadian rhythm within animals that keeps them in time with a 24-hour cycle. ![]() “Diurnal” refers to animals that are most active during the day and sleep at night. “Nocturnal” refers to animals that are most active at night and sleep during the day. Other creatures are crepuscular in order to avoid the heat of midday. In turn, some predators have adapted to being crepuscular as a means of better tracking their prey. The coarse light of twilight makes it challenging for both nocturnal and diurnal predators to see. Scientists believe that some animals have evolved these patterns of activity as anti-predator adaptations. Matutinal animals are most active in the morning while vespertine animals are most active at dusk. The word “crepuscular” is derived from the Latin word for “twilight.” There are subdivisions of crepuscular animals. Read on to learn why this is an efficient way for them to live and what local creatures live this way. ![]() ![]() This differs from animals that are nocturnal or diurnal. They tend to sleep at night and lay low during midday. With all this variety, what are the common traits that make them crepuscular?Ĭrepuscular creatures are most active at dawn and dusk. They live in the high mountains, sage plains, ponderosa forests, desert canyons and everywhere in between. MK Thompson/San Juan Mountains AssociationĬrepuscular creatures abound in Southwest Colorado. ![]()
