Japanese White-eye

Here is the picture of Japanese White Eye bird that I saw in Minahasa highland of North Sulawesi Province of Indonesia. It is only a small but beautiful bird.  

The Japanese White-eye, also known by its scientific name Zosterops japonicus, is a small bird native to East Asia. It has a greenish upper body, a yellow throat and chest, and a distinctive white ring around its eyes. This white eye-ring gives the bird its name. The species is also commonly called the Mejiro in Japan.

Japanese White-eyes are small and agile. They typically measure around 10 to 12 centimeters in length. Their diet includes insects, nectar, and various fruits. They use their sharp beaks to feed on soft fruits and to catch small insects. These birds are active and often move quickly through trees and bushes in search of food.

The Japanese White-eye is known for its pleasant and soft calls. It is a social bird that often forms small flocks, especially outside of the breeding season. During breeding, pairs build small cup-shaped nests in trees or shrubs. The female usually lays two to five eggs. Both parents help in feeding the chicks after they hatch.

These birds are adaptable and can live in various habitats. They are found in forests, gardens, and even urban parks. Because of their attractive appearance and singing, they have sometimes been kept as pets in the past.

Discovering the Black-naped Oriole: A Tropical Jewel of the Canopy

Hidden within the dense canopies of tropical forests, the Black-naped Oriole (Oriolus chinensis) flashes a brilliant yellow that instantly catches the eye. A striking bird of Southeast Asia and parts of the Indo-Pacific, it is a favorite among birdwatchers and nature photographers for both its beauty and elusive behavior.

Black-naped Oriole (Oriolus chinensis)
Black-naped Oriole in the little forest of Tounelet slope in Sonder town of Minahasa regency

A Splash of Yellow in the Forest
The Black-naped Oriole is easily recognized by its bright yellow plumage, contrasting with a distinctive black line that runs from the beak, through the eyes, and down the nape of its neck—hence the name. Its pinkish to orange bill adds to its vibrant appearance. The males and females look quite similar, although juveniles can appear slightly duller.
This colorful oriole is often heard before it's seen. Its clear, fluty whistles echo through the forest, sometimes mistaken for those of other birds. It is most active in the early morning, foraging high in the canopy for fruits and nectar of flowers.
Habitat and Range
The Black-naped Oriole is widely distributed across South and Southeast Asia, including the Philippines, Indonesia, parts of China and India. It prefers lowland and montane forests, secondary growth, and even parks and gardens where tall trees are abundant.
In regions like Minahasa Highland of Indonesia, where I photographed this individual (see image above), it can be spotted darting among the tall trees of the tropical rainforest. These forests provide the ideal habitat for the oriole to nest, feed, and thrive.

Black-naped Oriole in Minahasa highland
Black-naped Oriole can easily be recognized among the green leaves of trees in the little forest of Tounelet Slope of Sonder town in Minahasa highland

Behavior and Breeding
The species is generally solitary or found in pairs, although small family groups are sometimes seen. They are known for their swift, undulating flight and their ability to move deftly through thick foliage.
During the breeding season, which varies depending on the region, the Black-naped Oriole constructs a deep, cup-shaped nest slung like a hammock between forked tree branches. The female usually lays 2 to 3 eggs, and both parents share duties of incubation and feeding the chicks.
Conservation and Significance
Currently listed as a species of Least Concern by the IUCN, the Black-naped Oriole remains relatively widespread and stable in population. However, habitat loss due to deforestation poses a growing threat in some parts of its range.
For birders and naturalists, seeing a Black-naped Oriole in the wild is always a treat. Its vivid color, melodic calls, and graceful presence serve as a reminder of the biodiversity still thriving in the forests of Asia and the Pacific.
Final Thoughts
Whether you're an avid birdwatcher or simply a lover of nature, the Black-naped Oriole is a bird worth seeking out. Keep your eyes on the treetops and your ears open—you just might catch a glimpse of this yellow jewel darting through the leaves.

When I saw the bird, it was walking on the ground at a roadside. I tried to walk closer. Perhaps, the bird felt intimidated, so, it flew and landed on a branch of a tree. However, it was still within the reach of my camera. I made several pictures of the bird.

I also saw several other species such as Purple Heron, Collared Kingfisher, Brown-throated Sunbird, Hair-crested Drongo (white-eye), Sooty-headed Bulbul and Finch-billed Myna. 
When I walked deeper and longer into the forest, I could see more interesting species such as Yellow-billed Malkoha, Sulawesi Myzomela, Sulawesi Cuckoo-dove, Sulawesi Hanging Parrot, Gray-sided Flowerpecker, Crimson-crowned Flowerpecker, Crimson Sunbird, Mountain White-eye, Black-crowned White-eye and etc. 
A lot of people in Indonesia keep this bird in cage as pet. In certain cities in Indonesia, they conduct sound contest of their zebra doves. As the prize, winners get car, motorcycle, tv, fans and gas stove or money. 


The Zebra Dove: A Gentle Songbird of the Tropics

The Zebra Dove (Geopelia striata) is a small, graceful bird known for its soft, melodious calls and beautifully patterned plumage. Native to Southeast Asia, particularly Indonesia, Thailand, and Malaysia, the Zebra Dove has also been introduced to many other tropical regions, including Hawaii and parts of the Pacific Islands, where it has adapted well to urban and rural settings alike.

Appearance

Zebra Doves are easily recognized by their slender bodies and long tails. Their plumage features a delicate blend of browns and grays, with distinctive black-and-white barring across the neck, chest, and wings — a pattern that gives the bird its common name. The underparts are generally pinkish-gray, and their eyes are pale blue or gray, adding to their gentle appearance.

Behavior and Habitat

These doves are ground feeders and are often seen foraging for seeds and small insects in open spaces, roadsides, gardens, and parks. They are known for their calm temperament and tend to be solitary or found in pairs rather than large flocks.

Zebra Doves are especially known for their pleasant, cooing song, which is soft, rhythmic, and repetitive — a sound that is often associated with peace and serenity in the tropics.

Breeding and Nesting

Zebra Doves breed throughout the year in favorable climates. They build simple nests from twigs and grass, usually placed in bushes, trees, or even in man-made structures. Both the male and female share responsibilities in incubating the eggs and feeding the young.

Cultural Significance

In some parts of Southeast Asia, the Zebra Dove is prized for its voice, and dove song contests are popular. In these competitions, birds are judged on the quality, clarity, and rhythm of their calls. As a result, some people keep these birds as pets, though they are also widely appreciated in the wild for their natural presence and song.

Conservation

Currently, the Zebra Dove is not considered threatened and is classified as a species of Least Concern by the IUCN. Their adaptability to human environments and diverse food sources contributes to their stable population. However, like all wildlife, they benefit from healthy ecosystems and thoughtful coexistence with humans.


---

Conclusion

The Zebra Dove is a charming representative of the avian world, admired for both its appearance and gentle vocalizations. Whether seen perched quietly on a branch or heard cooing softly in the morning, this bird adds a serene touch to the landscapes it inhabits.

Bird Photography Tour in Tangkoko Nature Reserve, Mount Mahawu and Sonder's Farm Forest

A Trip Report by Charles Roring

Manado city - Temboan Hill - Tangkoko Nature Reserve
In late April 2025, I guided a Dutch photographer on 1 week bird photography tour across Minahasa Peninsula of North Sulawesi of Indonesia. I met my client at Sam Ratulangi Airport of Manado city and then continued our trip by car to Tangkoko Nature Reserve. It took around 2 hours to reach it. For the next 4 days 3 night s exploring the forest of Tangkoko, the coastal area of Batu Putih village, Temboan Hill, the man-made lake. There we watched and photographed a lot of species of birds. It was th first place that we stopped to watch and take pictures of birds.

Temboan Hill at the edge of Tangkoko Nature Reserve
For photographer, Temboan Hill is the most recommended site to visit. A D-SLR camera with 600 mm lens is the recommended device. There, we saw and photographed Knobbed Hornbill, Sulawesi Dwarf Hornbill, Sulawesi-crested Myna, Sulawesi Hanging Parrot, Pygmy Hanging Parrot, Yellow-billed Malkoha, Green Imperial Pigeon, Black-naped Fruit-dove, Gray-cheeked Imperial Pigeon, Sahul Sunbird, Crimson Sunbird, Yellow-sided Flowerpecker, Gray-sided Flowerpecker, Minahasa Racquet-tail, Black-billed Koel, Sulawesi Cicadabird, Sulawesi Brush Cuckoo. We spent several days walking inside the rainforest of Tangkoko which was the habitat of kingfishers. There were Sulawesi Dwarf Kingfisher, Lilac Kingfisher, Green-backed Kingfisher. Ashy Woodpecker, Spot-tailed Goshawk, Blue-backed Parrot, White-necked Myna could also be seen there. We tried to find Great-billed Kingfisher along the riverside but we were not so lucky. We saw the bird but it was impossible to take picture of the kingfisjlher. He was sitting on a big branch of a tree behind twigs and leaves. We could only see other birds such as Barred Rail, Little Egret and Nankeen Night Heron. The parking lot of Tangkoko was a good site for observing Sulawesi Bear Cuscus. We saw some interesting birds there too including Speckled Boobook, Brahminy Kite and White-bellied Sea Eagle.
At night, we saw and photographed Sulawesi Scops Owl. It was sitting on the branch of a tree near the birding lodge where we stayed. In the morning we saw Isabelline Bush-hen was swimming in a "little water pond" in the middle of the unpaved road that connected our birding lodge with the main road.
There was a man-made lake located between Temboan Hill and Batu Putih village where the birding lodges and homestays were. Oriental Darter, Purple-winged Roller, Slender-billed Crow, Little Grebe, Little Heron, White-breasted Waterhen were seen there.

Tangkoko - Manado city - Tomohon - Lake Linow
We continued our trip to Tomohon town which was around 2 hours ride from Tangkoko. There were several birding sites that we visited during our 3 days/2 nights in Tomohon. Lake Linow was the first site that we went to after arriving in Minahasa highland. For water birds, we went to Lake Linow
We saw and photographed Little Egret, Cattle Egret, Javan Pond Heron, White-breasted Waterhen, Barn Swallow. We saw terns sitting on the other side of the lake. It was difficult to identify them, too far. We could not spent much time at the lake. Heavy rain started to cover the lake area and its surroundings.

Tomohon town - Mount Mahawu
In Mount Mahawu, we saw and photographed the famous Scaly-breasted Kingfisher, Sulawesi Pitta, Snowy-browed Flycatcher, Sultan's Cuckoo-dove, Warbling White-eye, Turquoise Flycatcher, Citrine Canary Flycatcher and etc. Going to Mount Mahawu too early in the morning was not always a good idea. When we arrived there was strong wind, and the whole forest was covered by fog. In addition to Mount Mahawu, we also visited a restaurant that was surrounded by flower garden. Sulawesi Myzomela, Sahul Sunbird and Yellow-sided Flowerpecker were the birds that we saw there.

Sonder's farm forest in Minahasa highland
Sonder's Farm Forest
We also went to Sonder's farm forest, around 30 minutes drive from Tomohon town. We saw Crimson-crowned Flowerpecker, Crimson Sunbird, Sulawesi Myzomela, Black-crowned White-eye, Warbling White-eye, Black Sunbird, Yellow-billed Malkoha. On my previous trip to that site in one morning I saw Black Kite, Sulawesi Goshawk, Black-naped Oriole and White-faced Cuckoo-dove, Black-faced Munia, White-breasted Woodswallow. Sonder's farm forest was not a pristine forest but has got good open areas to watch and photograph birds. Actually there were several more birding sites in Subdistrict Sonder that we had not visited during this trip.
In our last day in Tomohon, we visited Mount Mahawu again in the afternoon. We saw the Sultan's Cuckoo-dove, and a lot of small birds that I have mentioned above. There was Superb Fruit-dove but he flew when we walked closer to photograph him. We left Tomohon for Manado city at around 10:00 a.m. Arriving at Sam Ratulangi International Airport, I said thank you, good bye to my client.
