Louvre glass windows of a Wooden House

Louvre glass windows are commonly used in timber framed houses in tropical region. The minimum thickness of the glass is 3 millimeter. The following photograph shows the passive ventilation of a house in Wasior town of West Papua province of Indonesia. The glass windows attached inside wooden frames were installed around the outer walls. Below the corrugated clay roofs are the jalousie windows made of timber. Because the humidity in this tropical island is high, the louvre and jalousie windows greatly reduce the moisture inside the wooden house and improve the indoor air quality of the rooms.

We all know that the temperature in tropical region is quite high between 30 to 32 degrees Celcius during the days. Louvre glass windows can enhance the air circulation inside a house without the help of fan. The maintenance cost is also low. However louvre windows are not suitable for passive ventilation in cold region. This was written by Charles Roring

Wooden Furniture from Leilem

Wooden furniture is always attractive. The natural color of wood with beautiful grains is always the most sought after material in furniture industry. There is a village in Indonesia that is famous for its furniture products. Its name is Leilem. Located in the province of North Sulawesi, Leilem can easily be reached by car from Manado city. When entering the village, visitors will be able to see boards that are arranged in inclined position in front of the villagers houses. These wooden planks, and blocks, facing the sun, are being dried before undergoing further treatment.

When the wooden planks have reach the desirable dryness, they will be planed and sewn in particular sizes. Then they will be assembled and nailed or pinned to form a cabinet or table. Majority of the buyers come from the surrounding towns and villages in Minahasa but in recent years, through the promotion on the internet, the number of national and international customers is increasing. Here, people can buy tables, beds, desk and bookshelves. The furniture can be sent overseas using containers. The same thing also happen to wooden houses in the nearby Woloan village that are sold to foreign buyers. The types of wood that the carpenters like to use are linggua, and nangka (jackfruit). Customers from such countries as the United States and the Netherlands prefer knock-down tables or chairs that are made of teakwood.

The manufacturers in Leilem village realize that they cannot rely on wood that is directly cut from forests in Minahasa. The supply of wood is dwindling now. Most of them are going to the southern region of Minahasa to find wood. With the price of teak and linggua wood is extremely high, farmers in Minahasa are now considering of planting trees to meet the market demand. It will take at least 25 years before trees can reach a minimum diameter for cutting.

Adventure in Raja Ampat

Adventure in Raja Ampat

As a tourist guide, I offer adventure tours for tourists who are interested in exploring the islands, beaches, coral reef, karst and rainforest of Raja Ampat. The tour will be started from Sorong city which is the gate to the islands. We will cross the sea by fast boat, first, to Waisai town (the capital of Raja Ampat regency). It takes around 2 hours to reach it. After that we will go to a guesthouse located at the beach.
After the long boat trip, we could take a rest for 1 hour to refresh our body. We can enjoy snorkeling and freediving at the house reef of the guesthouse. Participants of this tour need to bring their own mask, snorkel and fins.

Snorkeling, freediving and Taking Pictures and Videos Underwater

Diagonal Sweetlips

A good underwater camera or action camera is also useful for taking pictures of the coral reef, fish, blue sea star and other marine creatures in the water. I personally use Nikon Coolpix W300 or Fujifilm XQ2 with waterproof housing. In the past, I used an action camera, Brica B-Pro5 Alpha Edition. Taking pictures underwater is quite challenging especially for those who do freedive for the first time. There are waves, water current. The light in coral reef is less than on land. Freedivers usually use weights to help them go into deeper water. I don't use weights. The maintain a stable position while taking pictures in the water, I hold my breath for a little bit more than one minute and then hold a hard coral with my left hand. My right hand will be then one that holds the camera and press the shutter button.
There are a lot of species of fish which snorkelers and freedivers can see in the coral reef including damselfish, goatfish, black-tip reef shark, trevally, wrasse, parrotfish, blenny, gobby, dottyback, puffer, frogfish, and a lot more. To take pictures of them, I position myself as lower or flat as possible in the water so that I will be on the same eye level with the fish. This is quite difficult because of the buoyant force that pushes me to the surface. Holding rock, and making my body as calm as possible will help me to attract fish. When fish are closer and within a good shooting distance, I will aim my camera and shoot them. After spending around 1 hour snorkeling and freediving, we will go back to the beach and take a rest.

Birding

Red Bird of Paradise

In the evening, just before the sun disappears in the west, we can see more activity of birds in the forest edge. Birds such as Eclectus Parrot, Sulphur-crested Cockatoo, Palm Cockatoo, Red-cheeked Parrot, Great-billed Parrot, Violet-necked Lory, Pied Imperial Pigeon, Pinon Imperial Pigeon, Rufous-bellied Kookaburra, Sacred Kingfisher, and Willie Wagtail are quite active along the forest edge and coastal area.
Visitors need a good pair of binoculars to watch them. I personally use Visionking 10×42mm to watch birds. The famous brands that birdwatchers use are Swarovski, Leica, Nikon. Bringing a spotting scope with a tripod will also enhance the birdwatching experience.

Sightseeing Tour

Piaynemo Karst

The next few days will be spent in various parts of Raja Ampat. We will go by boat to karst islets that are quite far from the guesthouse where we stay. We will also visit sand bank located at sea, and swim at the beach of tropical islands. A trip to a coastal village can also be organized. Because most of this trip will be conducted by boat, participants of the tour must bring waterproof bags that can protect their cameras and other electronic devices during the trip.
Raja Ampat islands and Papua as a whole are beautiful. There is a pop song in Indonesia whose lyrics say: Surga Kecil yang Jatuh ke Bumi meaning Little Heaven that falls on earth.
It is important for us to preserve its rainforest and marine environment. Ecotourism is one of the solutions that can generate alternative income to the local people. When people get positive benefits from this environment, they will protect it.

Freediving Photos from Raja Ampat

Snorkeling

I am guiding a Dutch lady this week on a snorkeling and freediving trip in Raja Ampat. We stayed at a guesthouse in Waigeo island run by a Papuan family. The coral reef at the front of the guesthouse is very beautiful and is the natural habitat of a lot of species of fish and other marine creatures.
This morning I gave an introductory snorkeling lesson to her. It was the first time for her to learn snorkeling. She practiced snorkeling in shallow water at depths of 1 to 1.5 meters. Wearing a life-jacket, mask, snorkel and water shoes, she started swimming to deeper area to see such fish as moorish idol, goatfish, striped surgeonfish, convict surgeonfish, damselfish, longfin spadefish, and butterflyfish. She was very happy to see the marine life.

Marine Life in Raja Ampat

After giving her a short snorkeling lesson that morning, I continued my exploration of the coral reef alone. With an action camera in my hand, I enjoyed freediving for approximately 45 minutes. I descended to a depth of 5 to 7 meters to find anemonefish, sea-star, Christmas tree worm, and grouper. I was able to take some good pictures of the underwater world of this beautiful marine environment.
In the afternoon, we had a tour around the King's karst, a tidal cave and a lagoon in Gam island. We really liked this adventure especially this July. The wind was strong and the sea surface was rough. During July, very few tourists come to Raja Ampat because weather is bad and the sea is mostly covered by whitish big waves. During the adventure tour by boat, we did some birding. From that afternoon trip, we saw Lesser Frigatebird, White-bellied Sea Eagle, Spice Imperial Pigeon, Beach Kingfisher, Sulphur-crested Cockatoo, Brahminy Kite, Eclectus Parrot, Hooded Butcherbird, Pacific Swallow, Crested Tern, Brown Cuckoo Dove, and White-breasted Woodswallow.

Blue Sea Star and white Sea Worm

To watch birds, we used 10×42 mm binoculars. For taking pictures of them, we used Canon SX430. For underwater photographs, I used Brica B-Pro 5 Alpha Edition.
As a tourist guide, I offer a combined snorkeling, sightseeing, island hopping and birding tour to Raja Ampat for tourists who are interested in seeing the birdlife, marinelife and beautiful landscape of this tropical islands. If you want me to be your guide, please, contact me (Charles Roring) by email to: peace4wp@gmail.com or by whatsapp to: +6281332245180. I will be happy to organize your trip and guide you around this marine paradise.

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
