What makes the nightjar so unique? This mysterious bird, often called the "goatsucker," has fascinated people for centuries. Nightjars are nocturnal, meaning they are most active at night. Their cryptic plumage helps them blend seamlessly into their surroundings during the day. These birds have a wide, gaping mouth perfect for catching insects mid-flight. Unlike many birds, nightjars don't build nests; instead, they lay their eggs directly on the ground. Their eerie, haunting calls can be heard echoing through forests and grasslands at dusk. Nightjars also have an unusual habit of perching along branches rather than across them. This unique behavior, along with their silent flight, makes them one of nature's most intriguing creatures.
