Detailed description of great eared-nightjar
General Appearance: The Great Eared-Nightjar is a large nocturnal bird known for its distinctive ear tufts and cryptic plumage. The plumage is a mix of brown, black, and gray with intricate patterns that provide excellent camouflage against the forest floor. The face has a rufous hue, and the pale throat patch is often visible. Its tail is long and broad, giving it a fan-like appearance in flight. The wings are pointed, aiding in its silent flight. Male vs Female: In the Great Eared-Nightjar, sexual dimorphism is minimal, with males and females appearing quite similar. Both sexes share the same complex pattern of plumage color that makes them hard to distinguish. However, in some subspecies, males might have slightly longer tail feathers with more pronounced white spots or tips. Juvenile: Juvenile Great Eared-Nightjars differ from adults primarily in their plumage. While they maintain the same overall cryptic coloration, their feathers are fresher and often less worn than those of adults. The intricate patterns are not as defined, providing slightly less effective camouflage. As they age, their plumage gradually takes on the more crisp and detailed patterns seen in mature birds.
Breeding and nesting habits of the great eared-nightjar
Mating behaviors
The Great Eared-Nightjar exhibits a fascinating array of mating behaviors during courtship. Males are often seen performing aerial displays to attract females, which include fluttering flight patterns and soft calls that resonate through their habitat. These birds are monogamous, forming strong pair bonds. Occasionally, cooperative breeding has been observed, with non-breeding individuals assisting parents in various roles, emphasizing their social nature during the breeding season.
Nesting details
Nesting for the Great Eared-Nightjar is a simple affair, as they choose to lay their eggs directly on the forest floor or amidst leaf litter instead of constructing a traditional nest. They prefer dense forested areas where the ground cover provides adequate camouflage from predators. These nightjars are highly adaptable and occasionally nest in gardens, especially those mimicking forest-like foliage. To create a suitable habitat for them, one might enhance mulch cover, and plant shrubs to provide a natural canopy.
Eggs and chick-rearing
The female lays one to two eggs, which are remarkably camouflaged against the forest floor. Both parents actively participate in the incubation process, which lasts about 18 to 21 days. Once hatched, the chicks are precocial, meaning they are relatively mature and mobile from the moment of birth. Parental care extends for several weeks, during which both male and female diligently protect and feed the young, ensuring their smooth development into fledglings before encouraging independence.
What does a great eared-nightjar like to eat?
Natural Diet
The Great Eared-Nightjar primarily feeds on a balanced diet of insects, including moths, beetles, and crickets, which they skillfully catch in flight during their nocturnal hunts. Their diet is augmented by other small flying insects available in their forested habitats. During times of scarcity or seasonal changes, they may opportunistically forage on ground-dwelling invertebrates or consume the nectar and pollen from flowering plants to supplement their nutritional needs. Their feeding activity aligns closely with dusk and dawn when insects are most abundant.
Bird Feeders
While the Great Eared-Nightjar is not a frequent visitor to traditional bird feeders, they may be enticed by offerings that mimic their natural food sources if they come across them. Feeders that provide mealworms or insect-rich suet may attract them as an occasional snack. However, as their diet is predominantly insectivorous, they might not show sustained interest in seed mixes or fruits typically used for attracting other bird species. To attract these elusive nightjars, ensuring a habitat with ample insects and low-intensity lighting that does not disrupt their natural hunting patterns is more effective than standard feeder provisions.
Choose a ground-level platform feeder
Great Eared-Nightjars prefer feeding from the ground or elevated platforms. Select a low-mounted platform feeder in your backyard to mimic their natural feeding habits. Ensure the tray is spacious enough for them to land and feed comfortably during their dusk and dawn forays.
Treat them with bug-rich snacks
Great Eared-Nightjars primarily feed on insects, so offering them mealworms and crickets will be particularly enticing. You can mix these with Bird Buddy seeds to create an irresistible blend that caters to their dietary needs. Lay the mix on the platform feeder to attract these night flyers.
Strategic placement for peace and quiet
Since these birds are shy and nocturnally active, position feeders away from busy walkways and bright lights. Place them in a quieter part of the yard, near dense shrubs or treelines, which can provide a semblance of their native habitat and a sense of safety.
Cater to seasonal sensibilities
Seasonal weather changes can affect insect availability. During cooler months when insects are scarce, supplement their diet with nutrient-rich Bird Buddy seed mixes to ensure they're healthy year-round. This also helps attract them during breeding seasons when their dietary demands are heightened.
Add shallow water sources
Great Eared-Nightjars require water for drinking and occasional preening. Provide them with a shallow bird bath or a mini pond near the feeder. Keep water sources clean and slightly secluded, aligning with their preference for quiet, undisturbed habitats.
