Hispaniolan Nightjar in Los Haitises: Nocturnal Habits, Calls and Forest Habitat
When daylight fades over Los Haitises National Park, the forest becomes a different place. Many daytime birds settle down, insects become active, and the sounds of the natural environment begin to change. This quieter period is also when nocturnal birds become more interesting to wildlife enthusiasts.
One of the night birds associated with Hispaniola is the Hispaniolan Nightjar (Antrostomus ekmani). This elusive species is adapted to life after sunset. Its mottled plumage helps it blend into natural surroundings, while its large eyes and wide mouth are useful features for a bird that searches for insects in low light.
The Hispaniolan Nightjar is included in the published bird checklist for Los Haitises National Park. Older conservation documents for the park also mention the species under the scientific name Caprimulgus ekmani. However, it is important to understand that a species appearing on a park checklist does not mean it is easy to find there or commonly encountered by visitors.
This guide explains what makes the Hispaniolan Nightjar distinctive, how it behaves at night, what its calls can tell observers and how to appreciate nocturnal wildlife responsibly when visiting the Los Haitises region from Sabana de la Mar.
What Is the Hispaniolan Nightjar?
The Hispaniolan Nightjar is a member of the nightjar family, Caprimulgidae. Its currently used scientific name is Antrostomus ekmani.
It is endemic to Hispaniola, the Caribbean island shared by the Dominican Republic and Haiti. This means its natural range is restricted to this island rather than extending throughout the Caribbean.
Nightjars are well adapted to activity around dusk and during darkness. Many species have cryptic plumage that makes them difficult to distinguish from leaves, soil or tree surfaces when resting.
The Hispaniolan Nightjar follows this general nightjar pattern. Its colors and behavior help it remain inconspicuous during daylight, while its feeding habits are associated with catching insects in low-light conditions.
Why is it called a nightjar?
The word nightjar is commonly used for birds in the Caprimulgidae family. Many members of this family are most active around sunset, at night or during the early hours before sunrise.
They are sometimes confused with owls because both groups include nocturnal birds. However, nightjars are not owls. Their body shape, feeding methods and family classification are different.
Is it found in Los Haitises?
Yes, the Hispaniolan Nightjar appears on the Avibase checklist for Los Haitises National Park. It is also included in an older park management plan's list of important bird species.
The older document uses the name Caprimulgus ekmani, while the more recent checklist uses Antrostomus ekmani. These names refer to the same species under different taxonomic treatments.
These records support including the nightjar in a guide to the park's birdlife. They should not be interpreted as evidence that the bird is regularly seen on ordinary tourist excursions.
How to Recognize the Hispaniolan Nightjar
Nightjars are not always easy to identify. Their camouflage is highly effective, especially when they rest motionless on the ground or among vegetation.
The Hispaniolan Nightjar has a combination of features that can help an experienced observer recognize it.
1. Mottled brown and dark plumage
Its upperparts are generally patterned with dark brown, blackish and buff tones. The irregular pattern helps break up the outline of the body.
This camouflage can make the bird resemble dry leaves, bark or the forest floor. In low light, even a nearby bird may be difficult to notice.
2. A buff-colored throat area
A buff or pale throat collar is described in identification references. This feature may help observers distinguish the bird when lighting and viewing conditions are suitable.
3. Pale markings on the breast
The breast has pale spots with darker borders, creating a patterned appearance rather than a single uniform color.
These markings are useful identification details, but they may not be obvious when the bird is resting in deep shade.
4. Large eyes
Nightjars have relatively large eyes suited to seeing in low-light conditions. Their vision helps them operate during periods when many daytime birds are inactive.
A nightjar's eyes can sometimes reflect light when illuminated, but observers should never use strong or repeated artificial lighting simply to produce this effect.
5. Long wings and a wide mouth
Nightjars have long wings that help them fly while searching for insects. Their mouth is broad, an adaptation associated with catching flying prey.
The bill itself may look small compared with the width of the mouth. This is a common feature of nightjars and can seem surprising to people seeing one for the first time.
Where Does the Hispaniolan Nightjar Live?
The Hispaniolan Nightjar is endemic to Hispaniola, but it should not be described as equally common throughout the island.
Specialist birding references describe it as an uncommon and locally distributed species. They report it mainly from wooded habitats in parts of the Dominican Republic, including areas of the Sierra de Bahoruco and Cordillera Central.
Mixed woodland and other suitable forest environments are important in its reported distribution. Some locations are better known for nightjar observations than others.
What about its habitat in Los Haitises?
Los Haitises has a distinctive landscape of forest, limestone hills, coastal vegetation and mangroves. The park's bird checklist and historical management documentation include the Hispaniolan Nightjar.
However, the available records do not establish that every forest area in the park is suitable for the species or that it is regularly encountered around the main visitor routes.
Visitors should therefore treat the nightjar as part of the park's documented bird diversity, not as a guaranteed sighting.
Why does woodland matter?
Wooded habitats provide resting places, potential nesting areas and access to insects. The structure of vegetation can also influence how easily a nightjar can hunt and remain hidden.
Different forest types can support different bird communities. Protecting a variety of natural habitats is therefore important for maintaining the island's wildlife.
Why Is the Hispaniolan Nightjar Active at Night?
The nightjar's activity pattern is one of its most distinctive characteristics.
Many nightjars become active around dusk, when daylight begins to disappear. Some continue feeding during the night, depending on local conditions and the availability of insects.
Feeding when insects are active
Flying insects can become active during evening and night-time hours. A bird that feeds on insects can take advantage of this food supply.
The nightjar's wide mouth and flight adaptations help it catch prey while moving through the air.
Avoiding the busiest daytime period
Being active at night also means the bird has a different daily schedule from many daytime forest birds.
This does not necessarily mean it is completely inactive during daylight. It may rest while relying on camouflage to remain hidden.
Resting quietly
A resting nightjar can be difficult to see because its plumage blends into the background. It may remain still rather than fly away immediately when a person passes at a distance.
Visitors should not approach a motionless bird simply because it appears unaware of their presence. Remaining undisturbed is important for its welfare.
What Does the Hispaniolan Nightjar Eat?
Nightjars are insect-eating birds. The Hispaniolan Nightjar is understood to follow this general feeding pattern, although a detailed species-specific diet list for Los Haitises should not be assumed without local research.
Potential insect prey for nightjars includes:
- Moths
- Beetles
- Flying insects
- Other small insects active around dusk and at night
Moths and other insects can be attracted to natural light sources, vegetation or areas where flying insects gather. A nightjar may hunt by flying through suitable feeding areas and capturing prey in the air.
How does it catch insects?
Nightjars use a wide mouth to capture insects during flight. Rather than picking most prey from leaves like some small forest birds, they are adapted to feeding on flying insects.
Their flight can include short movements and changes in direction as they pursue prey.
Why is this feeding behavior important?
Insect-eating birds are part of the food web that connects plants, insects and other wildlife.
By consuming insects, nightjars participate in natural predator-prey relationships. Their role is one small part of the ecological balance within Hispaniola's wooded environments.
Understanding the Calls of the Hispaniolan Nightjar
Calls are especially useful when observing nocturnal birds because visibility is often limited.
The Hispaniolan Nightjar can be difficult to identify visually at night. Learning its vocalizations can help birdwatchers recognize when a nightjar may be nearby.
However, not every sound heard after sunset belongs to this species. Frogs, insects, other birds and even distant human activity can produce sounds that are easily confused in a tropical environment.
Listen for repeated patterns
When you hear a possible nightjar call, listen for its rhythm and whether it repeats. Try to identify whether the sound comes from one fixed location or changes position.
A recording from a reliable bird sound library can help you compare a field observation with a known vocalization.
Why recordings are useful
Bird sound recordings are helpful for learning species calls before a trip. They can also help birdwatchers review an observation afterward.
Use recordings for learning rather than repeatedly playing them in the forest to attract a bird. Playback can disturb wildlife, particularly during breeding or territorial activity.
Keep expectations realistic
The availability of a recording does not mean that the bird will call during a visit. Vocal activity can vary according to time, weather, season and individual behavior.
A quiet night does not necessarily mean that the species is absent.
Hispaniolan Nightjar and Other Nocturnal Birds in the Dominican Republic
The Dominican Republic has several nocturnal bird species. Some belong to the nightjar family, while others belong to different bird families.
The Hispaniolan Nightjar is different from the Northern Potoo and the Ashy-faced Owl, both of which are also relevant to discussions of the country's night birds.
Hispaniolan Nightjar
The Hispaniolan Nightjar is an endemic nightjar associated with wooded habitats on Hispaniola. Its cryptic plumage and nocturnal habits make it a challenging bird to observe.
Northern Potoo
The Northern Potoo belongs to a different family. Potoos are famous for their upright resting posture and remarkable camouflage against tree branches.
Ashy-faced Owl
The Ashy-faced Owl is a true owl. It has a different body structure and hunting ecology from nightjars.
Understanding these differences helps visitors avoid grouping every night-active bird into the same category.
Why Is the Hispaniolan Nightjar Important?
The Hispaniolan Nightjar is important because it represents a distinctive part of the island's native biodiversity.
An endemic island species
Its restricted natural distribution makes the protection of suitable habitat on Hispaniola especially relevant.
A specialized insect predator
Its feeding habits connect it to the insects and other organisms living in wooded habitats.
Part of the park's documented bird diversity
The inclusion of the species in Los Haitises bird records adds to the park's importance as a place for wildlife conservation and nature study.
A reminder that wildlife is not limited to daylight
Many visitors focus on the birds they can see during daytime excursions. Nocturnal species remind us that natural habitats remain active after visitors leave.
How to Observe Nocturnal Birds Responsibly
Night-time wildlife observation requires extra care. Poor lighting, noise and unnecessary movement can disturb animals that are adapted to darkness.
If a permitted night-time nature activity is available in the area, follow these guidelines.
1. Follow authorized access arrangements
Do not enter restricted areas or protected forest zones after dark. Confirm whether night-time access is permitted before planning an activity.
2. Use lighting carefully
Use only the lighting permitted by the relevant park authority or guide. Avoid shining bright lights directly into a bird's eyes.
3. Keep noise low
Loud conversations, music and repeated playback can disturb nocturnal wildlife.
4. Stay on permitted paths
Walking off-trail at night can damage vegetation and increase the risk of disturbing resting animals.
5. Never handle a resting bird
A bird sitting on the ground may be resting or relying on camouflage. Do not touch it, pick it up or try to move it for a photograph.
6. Avoid disturbing potential nesting sites
Do not investigate suspected nests or nesting areas. Give wildlife space and follow any instructions from park personnel.
7. Do not assume sightings are guaranteed
A responsible wildlife experience respects the natural behavior of animals. A tour provider should not promise that visitors will see a particular wild bird.
Can You Photograph the Hispaniolan Nightjar?
Photographing a nightjar can be challenging because it is active in low light and often blends into its surroundings.
For anyone interested in nocturnal bird photography, the following suggestions may help:
- Use a camera with good low-light performance.
- Choose a suitable telephoto lens.
- Learn the bird's appearance before going into the field.
- Avoid approaching a resting bird.
- Do not use repeated flash photography.
- Follow the instructions of authorized guides.
- Never damage vegetation to create a clearer photograph.
If you cannot obtain a photograph, recording the date, location and observation details can still be valuable for personal nature notes.
Visiting Los Haitises from Sabana de la Mar
Sabana de la Mar is a useful starting point for exploring the eastern side of Los Haitises. The area is known for access to the park's coastal scenery, mangroves and limestone landscapes.
Most visitors explore the park through planned nature excursions. The specific route and activities depend on the tour provider and current access arrangements.
A daytime excursion can introduce travelers to:
- Mangrove ecosystems
- Limestone hills and coastal formations
- Forest landscapes
- Birdlife and other wildlife
- The natural environment around Samaná Bay
However, a regular daytime boat excursion should not be confused with a specialized nocturnal birdwatching activity.
If the Hispaniolan Nightjar is a priority for your trip, ask a provider whether an authorized night-time wildlife experience is available. Confirm the permitted location, timing, transport, guide arrangements and safety requirements before booking.
Do not enter the national park after dark independently or assume that all areas are open for night-time visits.
