The Ultimate In Birding Tours

South America (and its islands)



Birdquest’s Serra do Divisor, Remote Brazil Expedition in July 2021 is a unique and ‘one-off’ experience. This is a first-time-ever on a birding trip, special expedition to the Serra do Divisor on the Brazil-Peru frontier in far western Acre. (Note: we are not planning on repeating this expedition for at least 5 years.)

The main target here is the recently-described, little-known Acre Antshrike (a ‘Birdquest Lifer’), which is straightforward to find at Divisor, but the expedition will surely turn up plenty of other great birds. This is a poorly-known, very rarely-visited Amazonian national park. See the current park checklist below.

We shall stay at the basic park headquarters for 6 nights. The journey involves a flight from Rio Branco to the remote town of Cruzeiro do Sul and a boat trip of roughly 10 hours the following day. Yes, we really are talking ‘Remote’!

The expedition can either be taken by itself , as a stand alone trip, or as an expedition-style extension to the 2021 Brazil’s Southwest Amazonia tour.


Day 1: Arrive Rio Branco. Evening expedition start. Overnight at Rio Branco.

Day 2: Flight to Cruzeiro do Sul. Local birding. Overnight there.

Day 3: By boat to Serra do Divisor. Overnight there.

Days 4-8: Exploring Serra do Divisor National Park. Overnights at Serra do Divisor.

Day 9: Return by boat to Cruzeiro do Sul. Overnight there.

Day 10: Local birding, then flight to Rio Branco. Afternoon expedition end at Rio Branco airport.

Accommodation & Road Transport: The hotel in Rio Branco is of a good standard. Accommodation at Cruzeiro del Sur and at Serra do Divisor is simple. The limited road transport is by car or minibus/passenger van and roads are mostly good. Most transport is by air and boat!

Walking: The walking effort will range from easy to moderate.

Climate: Generally warm or hot. There will be a mix of sunny and cloudy conditions and some rain is likely. It will be rather humid.

Bird Photography: Opportunities during the expedition are expected to be worthwhile.

Please contact our office if you would like to join the expedition.


Here is an eBird list of species recorded from the area. It is still far from complete, as ornithological observations by skilled observers in the park have, so far, been very limited.
