Indonesia, spread across 17,508 islands and boasting over 1,600 bird species and over 600 endemics (far more than any other country on Earth!) should be at the forefront of every international birder’s destination list! Rockjumper is proud to offer an extensive suite of tours to this mind-bogglingly biodiverse region that includes this comprehensive exploration of the endemics-rich Lesser Sundas. This diverse and rugged chain of volcanic islands, stretching across the Java Sea between Bali and New Guinea, supports over 100 Indonesian endemics with more than 80 of these restricted to the Lesser Sundas. Our tour visits five of these islands (Sumba, Timor, Rote, Flores and Komodo) and targets every single one of the area’s localised and highly sought-after endemics occurring on these five islands, other than a few isolated species restricted to East Timor.

The Lesser Sundas fall within a region known as Wallacea and its avifauna is a startling mix of Asiatic and Australasian families. Starting and ending in Bali, we explore montane rainforests, lowland monsoon forests, wetlands, mangroves, coastal mudflats, grasslands, and dry scrub. We begin this epic birding adventure in eastern Sumba, where mouth-watering specialties include Red-naped Fruit Dove, Sumba Hornbill, Little Sumba Hawk-Owl, Sumba Boobook, Mees’s Nightjar, Sumba Green Pigeon, and the little-known Sumba Buttonquail. Our next leg of the tour takes us to West Timor and the tiny island of Rote, situated just off western Timor. Over the course of the next week, we hope to encounter avian specialties such as Timor and Rote Boobooks, Pink-headed Imperial Pigeon, Jonquil Parrot, Tricolored and the yet-to-be described Timor (Mt. Mutis) Parrotfinch, Flame-breasted Sunbird, Orange-sided and Chestnut-backed Thrushes, Cinnamon-banded Kingfisher, Black-banded Flycatcher, Timor and Black Cuckoo-Doves, Buff-banded Thicketbird, Timor Stubtail and Timor Sparrow to mention just a few!

We end the tour on Flores Island, where the magnificent Flores Hawk-Eagle, Glittering Kingfisher, sensational Ornate Pitta, Wallace’s Hanging Parrot, Leaf Lorikeet, Wallace’s and Flores Scops Owls, Flores Monarch and the superb Bare-throated Whistler will be among the many targets on the island. One of the undoubted highlights of the trip will be the visit to Komodo Island just off Flores, where 10ft (3m) Komodo Dragons roam this almost prehistoric paradise along with Green Junglefowl and Orange-footed Scrubfowl. Here we will also seek the beautiful and critically endangered, Yellow-crested Cockatoo. The Lesser Sundas has something very special to offer the keen birder and nature enthusiast and comprehensive, endemics-rich birding tour promises to be a classic among international birding adventures!

Tour Pace & Walking

Moderate to challenging birding, some basic lodging, one difficult hike (optional) & hot, humid conditions are taxing. Our Mega tours are very fast-paced birding adventures designed for the dedicated lister and serious birder. The focus of the tour is to see as many of the endemics and area specials as possible in our given time. In order to cover the necessary route to maximise the species list we tend to spend a single night at most sites and travel large distances. There is very little down time aside from that spent driving from one site to the next. These tours are not suitable for dedicated or avid photographers; inexperienced or new birders; as well as anyone with serious mobility or health challenges.


Most accommodations are reasonable to comfortable, but those in the Lewa area are basic.

Ease of Birding

Birding can be demanding at some locations. Low density of several key species. Others require repeat efforts. Several late evening/early mornings for nocturnal species.

Number of Species Expected

200 to 240 depending on time of year. Over 100 Indonesian endemics & over 80 endemic to Lesser Sundas

Other Attractions

large tracts of forest, rolling forested hills scenery, beautiful beaches and tropical island scenery, 10ft (3m) Komodo Dragons!

Photographic Opportunities

Photography can reasonable, despite the lack of hides & predominant forest birding.

What our clients say about us

Glen Valentine
LH & MN - Indonesia: Western Highlights 2019

We really enjoyed this tour, it felt like a holiday as well as a bird watching experience. Glen Valentine was an excellent guide, both in terms of bird spotting/knowledge, and also his affability and management of the group, and we will try to travel with him again.

Glen Valentine
MG - Lesser Sundas 2022

"Glen Valentine is an amazing guide and really made the trip special. He is personable, patient and unflappable. He did a fantastic job of getting everyone on the birds and this was really challenging in many cases. One of the best I’ve experienced. Our local guide was also very good at leading us to key areas and finding difficult birds. Some of the trip was challenging in Sumba, but well worth the effort. Overall, this was a fascinating and rewarding trip to a little known part of the world with lots of really exciting endemic birds!

Lev Frid
FH, Indonesia 2022

Both my husband and I found Lev to be an excellent guide. He was both personable and knowledgeable. I especially appreciated his calm demeanor when I was unable to immediately get on a bird in the field. His photographic skills also assisted in occasionally clinching an ID of a far-off bird. And, I and others on the Tour appreciated his willingness and ability to digiscope special birds - to be be later airdropped with each other! Lev is a real, and multi-faceted, gem.
