Birding in Sonder: A Hidden Gem in the Minahasa Highlands

Nestled in the cool, green heart of North Sulawesi, the highland district of Sonder in Minahasa Regency offers more than just scenic landscapes and fertile farmlands — it is a rising destination for birdwatchers and nature lovers. With its mixture of secondary forests, farmland edges, and traditional gardens, Sonder provides rich habitat for many species of birds, including several that are endemic to Sulawesi.

A Unique Habitat for Endemic Species

Sulawesi is known for its high level of endemism, and Sonder is no exception. Birders exploring this area often report sightings of:

• Sulawesi Myzomela (Myzomela chloroptera)

• Yellow-sided Flowerpecker (Dicaeum aureolimbatum)
• Sulawesi Leaf Warbler (Phylloscopus sarasinorum)
• Black Sunbird (Leptocoma aspasia)
• Grey-sided Flowerpecker (Dicaeum celebicum)
• Crimson Sunbird (Aethopyga siparaja) – not endemic but vibrant and regularly seen

These species are often seen flitting among banana groves, coconut palms, and native trees early in the morning. The cooler climate of the highlands provides a comfortable birding experience year-round.

Birding Sites and Accessibility

While not yet a mainstream birding destination, Sonder’s accessibility from Manado (just 1.5 hours by car) makes it a convenient stop for birders visiting North Sulawesi. Some key areas to explore include:

• Mount Lengkoan  – a hill area known to local birders, offering panoramic views and diverse avifauna.
• Farmlands and forest patches in Lalek Farm Forest, Tincep and Rambunan.
• Riverbanks and rice fields, especially in the early morning, are great for spotting herons, kingfishers, and swallows.

Supporting Local Ecotourism
Birding in Sonder also contributes to community-based ecotourism, offering locals opportunities to guide, host, or transport birders. With increasing interest in sustainable tourism, there’s potential to develop homestays, local guiding services, and conservation awareness programs.
