Birdwatching in Sonder of Minahasa Regency, Indonesia

If you are visiting the Province of North Sulawesi  in Indonesia, you have probably heard of the famous Tangkoko Nature Reserve. But just an hour away, high in the cool mountains, lies a quieter, hidden gem for nature lovers: Subdistrict town of Sonder.

Sulawesi Myzomela in Sonder's forest edge

Sonder is a small district in the Minahasa Regency, located near the city of Tomohon. Unlike the hot coastal jungles, Sonder offers a cool, breezy climate and a unique landscape where wild forests meet clove plantations and rice fields. This mix makes it a fantastic (and comfortable) place to see birds that you can’t find anywhere else on Earth.

Sulawesi Hanging Parrot

Why Go to Sonder?

Sonder is perfect for "relaxed birding." You don't always need to trek deep into a dark jungle to see amazing wildlife. Because the town is surrounded by gardens and forest edges, many birds come right out into the open.

Cooler Weather: It is much more comfortable to walk here than in the humid lowlands.

Easy Access: You can often spot rare birds just by walking along paved village roads or easy dirt trails near the Tounelet Slope Forest.

Unique Mix: You get to see both forest birds and open-field birds in one trip.

Warbling White-eye

The Stars of the Show

Sonder is famous for a few specific birds that travel from all over the world to see. Here is what you should look for:

1. The Sulawesi Scops Owl

This is the big prize in Sonder. While owls are usually hard to find, local guides in Sonder know exactly where these small owls sleep during the day. You can often see them roosting quietly in bamboo clumps or shady trees near the village edge.

2. The Sulawesi Myzomela

High elevation forest of Sulawesi is the habitat for Sulawesi Myzomela, and Sonder is one of the best places to find this specific highland type. This colourful bird often seen in the forest edge or flower garden. They like to hop from one flower to another feeding on nectar.

3. The Sulawesi Hanging Parrot

These tiny, bright green parrots are fun to watch. They hang upside down (like bats!) while they eat fruit and flower nectar. You will often hear their high-pitched squeaks before you see them zooming past the coconut trees.

4. The Yellow-billed Malkoha

This is a large, strange-looking bird with a long tail and a bright yellow beak. They love climbing through the vines in the forest canopy. They look almost prehistoric and are a favorite for photographers.

Some birds in Sonder: Yellow-billed Malkoha, Black-billed Koel, Black-naped Oriole, Sulawesi Myzomela

A Typical Birding Day in Sonder

The Morning Walk:

Your tour usually starts early, around 5:30 or 6:00 AM, when the birds are most active. You might start at the **Tincep's Kengkang Waterfall** area or the **Tounelet Forest**. As the sun rises, the mist clears, and you can see Green Imperial Pigeon and Sulawesi-crested Myna sit on the brancheals of trees that grow on the cliffs around the waterfall.

Black-naped Oriole

The "Edge" Advantage:

One of the best things about Sonder is "edge birding." This means you walk on the road where the forest meets the farm. Birds love this area because they can hide in the trees but come out to the farm to eat flowers, fruits, lychen, insects, reptiles. It makes spotting them much easier for beginners.

### Practical Tips for Your Trip

* **How to get there:** Sonder is about a 1.5-hour drive from Manado or just 20 minutes from Tomohon.

* **What to wear:** Wear comfortable walking shoes. Even though it is cool, bring a hat and light rain jacket, as mountain weather can change quickly.

* **Bring Binoculars:** Most birds are small and active. If you don't have your own, ask if your guide can provide a pair.

* **Hire a Local Guide:** This is crucial. The birds are good at hiding. Local guides know the specific trees where the Owls and Kingfishers like to sit.

### Summary

Sonder offers a peaceful, authentic side of North Sulawesi. It is not just about ticking birds off a list; it is about enjoying the cool mountain air, the smell of clove spices, and the thrill of spotting a rare owl right in a village backyard.

🐠 Discover Bunaken: Indonesia's Underwater Snorkeling Paradise

Nestled in the heart of the Coral Triangle off the coast of North Sulawesi, the Bunaken Islands are home to one of the world's most spectacular marine ecosystems. For snorkelers and marine enthusiasts, a tour here is a journey into an intensely vibrant, biologically rich underwater world—an absolute must-do for any trip to Indonesia.

Marine Tour in Bunaken National Park

The World of Bunaken National Park

The Bunaken National Park, established in 1991, spans nearly 900 square kilometers, with 97% of it being pristine marine habitat. It comprises five main islands: Bunaken, Manado Tua, Siladen, Mantehage, and Nain. This conservation area is renowned for its:

•  Exceptional Biodiversity: Hosting over 390 species of coral and more than 2,000 species of marine creatures, it represents 70% of all fish species found in the Indo-Western Pacific Ocean.
• The Famous Walls: Bunaken is characterized by dramatic, nearly vertical coral walls that drop from the shallow reef plateaus to depths of 25-50 meters. Snorkeling along the edge of these drop-offs offers a breathtaking view into the deep blue.
• Crystal-Clear Water: Visibility is often superb, reaching up to 30-35 meters, allowing for unparalleled viewing of the marine life from the surface.

🤿 Snorkeling: A Window to the Coral Reef

While Bunaken is globally famous for its wall diving, the shallow, fringing reefs and the tops of the drop-offs make it equally perfect for snorkeling.

Top Snorkeling Spots

Marine tours typically visit two or three stunning locations in a single day trip from Manado or the islands themselves. Some of the most celebrated spots include:

 * Lekuan Reef: These sites on Bunaken Island are famous for guaranteed sightings of Green and Hawksbill Sea Turtles gently grazing or resting on coral ledges. The shallow tops of the walls here are teeming with life.

 * Johnson's Wall and Alung Banua: Beautiful reef areas inside of Bunaken bay known for schools of butterflyfish, sweetlips, and parrotfish in the fringing reef.

 * Bunaken Timur (East Bunaken): A long stretch of reef along the eastern coast, ideal for drift snorkeling along the drop-off when the currents are mild.

 * Siladen Island: This smaller island boasts a vibrant reef drop-off and shallow seagrass meadows, offering a contrasting environment rich with smaller reef fish and often home to dugongs.

What to See

Bunaken's marine tours provide a high chance of encountering iconic creatures:

 * Turtles: You are practically guaranteed to see several species of sea turtles swimming gracefully or resting.

 * Reef Fish: Schools of dazzling reef fish, including colorful Clownfish (Nemo!) nestled in their anemones, angelfish, lionfish, triggerfish, and parrotfish.

 * Corals: Explore dense, healthy coral gardens with massive table corals, vibrant soft corals, and giant clams.

 * Pelagic Species: Keep an eye out into the blue for larger species like reef sharks, jackfish, barracudas, and, occasionally, even dolphins or pilot whales from the boat.

🛥️ Planning Your Marine Tour

Most visitors arrange day tours from the city of Manado (about 30-45 minutes by speedboat) or directly from resorts on Bunaken or Siladen.

| Feature | Details |

|---|---|

| Typical Tour Duration | 7-8 hours (full day) |

| Inclusions | Boat transfer, snorkeling gear rental, guide, lunch (often on Siladen Island), and mineral water. |

| Exclusions | Bunaken National Park Entrance Fee (mandatory contribution to conservation) and sometimes hotel transfers. |

| Best Time to Visit | The dry season, generally from April to October, offers the best visibility and calmest waters, though snorkeling is excellent year-round with water temperatures consistently at 28°C - 29°C. |

Tip for Travelers: Consider supporting local guides and homestay owner for a more authentic experience, and always be mindful of marine conservation by avoiding touching corals or marine life.

The Bunaken Islands truly offer a quintessential Southeast Asian marine adventure. It's not just a snorkeling trip; it's an immersion into one of the most biodiverse, living aquariums on the planet.

Birding in Mount Mahawu: A Simple Guide to North Sulawesi’s Hidden Avian Paradise

Mount Mahawu, a stratovolcano located near Tomohon in North Sulawesi, Indonesia, is emerging as a top destination for eco-travelers and birding enthusiasts. Surrounded by lush montane forest, scenic crater views, and cool highland air, Mahawu offers one of the most accessible and rewarding birdwatching experiences in the region. Whether you're a seasoned birder chasing endemics or a nature lover seeking peaceful hikes, birding in Mount Mahawu deserves a place on your itinerary.

Warbling White-eye

Why Mount Mahawu is a Birding Hotspot? 

The highlands around Mount Mahawu are part of the Biodiversity-rich Wallacea Region, famous for its high rate of endemism. The mix of primary forest, secondary growth, and open scrub provides habitat diversity that attracts both forest specialists and highland species rarely seen at lower elevations.

Key Reasons Birders Love Mount Mahawu

• Easy access: A paved road leads near the summit, and trails are well-maintained. 
• High bird diversity: Many endemic species of Sulawesi can be spotted in a single morning. 
• Cool, comfortable climate: The highland temperature makes birding enjoyable year-round. 
• Minimal crowds: Compared to more famous birding sites, Mahawu is still relatively quiet. 

Highlight Birds of Mount Mahawu

Here are some of the species that birders frequently target in the Mahawu area:

Sulawesi Endemics

• Sulawesi Hornbill (Aceros cassidix) 
• Sulawesi Pygmy Woodpecker 
• Sulawesi Myzomela 
• Sulawesi Blue-flycatcher 
• Sulawesi Drongo
• Yellow-billed Malkoha 

Highland & Specialty Species

• Scaly-breasted Kingfisher (rare but possible with patience) 
• Purple-winged Roller 
• White-bellied Imperial Pigeon 
• Crimson-crowned Flowerpecker 

In the early morning, the forest resonates with the calls of Bay Coucal, Yellow-sided Flowerpecker, and Sulawesi Crow. Photographing birds here is also rewarding thanks to good lighting and semi-open trails.

Best Time for Birding in Mount Mahawu

Birding is possible year-round, but the best months tend to be June to October, during the drier season. Early morning (6:00–9:00 AM) and late afternoon (3:30–5:30 PM) are prime bird activity periods.

Scaly-breasted Kingfisher

Recommended Birding Trails

1. The Crater Rim Trail

A short circular trail around the crater allows for easy birdwatching. You can pause at scenic viewpoints while listening for woodpeckers and flycatchers.

2. The Forest Trail Below the Parking Area

This lightly forested path is excellent for spotting endemics, especially mixed flocks of white-eyes, and small insectivores. This is typically where many bird guides start their morning outings.

3. The Mahawu Agricultural Slopes

The farmlands and open areas near the base attract doves, munias, and occasional raptors circling overhead.

Tips for a Successful Birding Trip

• Hire a local bird guide: Guides based in Tomohon or Sonder can help you find elusive species and understand vocalizations. 
• Bring binoculars and a telephoto lens: Forest birds often perch high or move quickly. 
• Wear earth-tone clothing: Helps avoid disturbing wildlife. 
• Go early: Mornings are quieter and allow you to catch the dawn chorus. 
• Be mindful of weather: Mist can roll in quickly on the highlands—be prepared. 

How to get to Manado city? 

Visitors who want to take this tour, need to fly to Manado city which is the capital of North Sulawesi Province of Indonesia.
