A better understanding of nocturnal life is critical to ensure its effective protection. However, given the environmental threat now facing the nocturnal world, this will have profound consequences should it remain unaddressed. The legacy of this inaccessibility remains a barrier to our understanding of nocturnal life today. This scientific blind spot is referred to as the “nocturnal problem”. Physical restraints on human navigation in the dark are partially responsible for this. The conservation of nocturnal species has therefore become urgent.ĭespite the abundance of night-time life, the understanding of nocturnal species has evaded science throughout history. Environmental change is severely threatening the ability of nocturnal animals to coexist with humans. The transforming night adds new sensory pressures concerning finding food, a mate, and navigating a world permeated by artificial illumination. The stifling night-time heat experienced across Europe this summer is indicative of this, placing nocturnal animals under even greater stress. Recent research has also shown that the night is warming considerably faster than the day. ![]() Ecologists suggest that the majority of land animals are either nocturnal or active across both the day and night. Intensive farming, suburban spread, artificially lit cities, and continuously busy road systems mean daytime species are becoming increasingly active throughout the night. ![]() The smallest is the bumblebee bat, weighing just 2 g - that's about two teaspoons of sugar.Human disturbance is rapidly changing the nature of the nocturnal world. The largest bat in the world is the gold-crowned fruit bat, with a wingspan of up to 6 feet (1.8 m).British bats also most definitely won't drink your blood.Which means they're unlikely to fly into your hair. They use sonar to detect their prey and other objects in the dark.In fact they're more closely related to monkeys! If you see a bat flying above the surface of a pond or river, it might be a Daubenton's bat. They can often be seen where there are trees around. Like other bats, pipistrelles are nocturnal, emerging at night for a couple of hours to hunt for insects to eat before returning to their roosts on a house, tree or building. They're tiny, with reddish-brown fur and blackish ears, nose and wings. If you’re patient, you might notice something smaller than a bird flitting hurriedly across the sky. Look up at dusk, when there’s still some light in the sky. (Also look out of the car window when you're driving at night.) If you're planning a Big Wild Sleepout in the country, you may be fortunate enough to catch a glimpse of the barn owl's ghost-like silhouette as it glides through the twilight searching for prey. It has a pretty heart-shaped face with a light-brown (almost golden-coloured) back and wings. The barn owl (pictured) is also nocturnal and is mostly found on farmland. Look out for them resting on a favourite perch, or being pestered by other birds in the daytime. Tawny owls can often be found in woodland, parks and gardens, and are around the same size as a pigeon, with a ring of dark feathers around their face, with large, dark eyes. You may be fortunate to hear a tawny owl, our largest common owl, make its famous call.īut did you know that it's the male tawny owl that goes 'twoooo' and the female that goes 'twit'? In June and July they are quiet, but they begin calling again in August. Most are nocturnal, or active at dawn and dusk (the fancy word for that is 'crepuscular'). ![]() Owls are specialised birds of prey with round heads and rather flat faces.
