Incredible sunsets were met with full checklists, full (and then empty) caipirinhas, and full stomachs back on our riverboat home, the Tumbira. Photo by guide Tom Johnson.

An extended voyage into remote areas full of amazing birds but infrequently visited by birders? Yes, please! This two-week tour of the Madeira-Tapajos interfluvium (south of the Amazon) was chock-full of birds and lots of adventure in a comfortable setting with fantastic company.

We kicked off this grand adventure in Amazonia in the bustling metropolis of Manaus where we boarded a comfortable and fast speed launch, checking out the meeting of the blackwater Rio Negro and the whitewater Solimoes just downstream from Manaus before blasting off. We shot down the Amazona and then up the Rio Madeira to the riverside town of Borba, cruising past Amazon River Dolphins, Horned Screamers, and Short-tailed Parrots along the way.

Borba was our home for three nights, and we used this frontier base as our hub of land-based exploration of the right bank of the Madeira. This was a location notable for the ornithological collections of Natterer, and an area that Bret has visited repeatedly due to its interesting avifauna. Contrasting with a fire-choked season during the tour in 2015, we were fortunate to bird several excellent forest tracts this without issue - well, our endless stream of replacement VW Combi vans notwithstanding! Fortunately, our team on the ground managed our vehicle problems and we were able to continue birding. We visited a mixture of different mosaics of terra firme forest and a campina patch, and also did some fruitful nightbirding. Bald Parrots, Least Nighthawk, White-winged Potoo, White-browed and Black-faced Hawks, Red-necked Woodpecker, Point-tailed Palmcreeper, and many more birds came through for us here. Bret's advance scouting to help find good trails and request access to private property was invaluable - thanks Bret! We also got to enjoy the culinary concoctions of Portuga and the ladies of Café das Meninas who woke up super early in the morning to make us coffee and eggs and tapioca with palm for breakfast. Mmmm - delicious!

After we wrapped up the land-based leg of the tour in Borba, we boarded the luxurious riverboat Tumbira with its fresh caipirinhas, air-conditioned cabins, and wonderful crew and prepared to travel farther east. The advantages of a boat-based exploration of the area between the Madeira and Tapajos Rivers (interfluvium) became clear as we woke up at different spots each morning and could easily land ashore using motor canoes and bird a variety of super forest trails. We also used Tumbira's upper deck to spot a huge diversity of birds including swifts, parrots, many raptors, and even a few surprises like foliage-gleaners and antbirds.

The boat-based portion of the tour was like a dream as we cruised small rivers that have rarely been birded before, crossing biogeographical boundaries and enjoying wonderful weather (we only got chased away from birding by rain a few times). In the evenings, we were entertained both by some wonderful nightbirding but also by multimedia slideshows from Bret (on Amazonian geologic history and biogeography) and Micah (on primates as well as his masters research on woodcreepers) - fascinating stuff.

Heading east from the Rio Madeira, we traveled the Paraná Urariá as our gateway to several tributary rivers including the Rio Abacaxis and the Rio Paracuní on our way to the Maués-Açu and the Rio Parauarí. After encountering low water levels in 2015, we tweaked the dates and this year, water was high enough that the Tumbira could get us just about anywhere we wanted to go. Though we couldn't find the hoped-for Golden Parakeets, we did visit an impressive variety of forest trails in terra firme forest, and that strategy eventually produced a major army ant swarm with attendant Harlequin Antbirds and Pale-faced Bare-eyes - WOW! We stood and watched in silence for over an hour as the antbirds hopped up on vertical stems and intently stared downward at the forest floor, hoping to snag arthropods flushed by the stampede of army ants. They weren't easy to spot, but we eventually all got to enjoy these fantastic antbirds (and a host of other ant-followers like Hoffmann's Woodcreeper, too).

After exploring south of Maués, we crossed back to the broad Amazona by way of the Paraná dos Ramos and enjoyed some bountiful island and river edge birding along the way back to Manaus. Red-billed Scythebill, Plain Softtail, Scaled Spinetail, and Varzea Piculet were among the target birds we found here. After the birding, we were even treated to an evening art salon in the dining room of Tumbira - Nancy and Micah shared some of their beautiful art with us. A final stop near Marchantaria Island allowed us to find some last minute specialty birds like Parker's Spinetail and flocks of migrant Stilt Sandpipers arriving from the north. We found our birds with a gorgeous sunset just moments away, and we motor-canoed back to Tumbira at dusk, the plan coming together like a dream.

Bret, Micah, and I would like to thank everyone for joining us on this stylish yet remote adventure into Brazil. You were all wonderful travel companions and your flexibility and adventurous spirits helped the success of this tour immeasurably. Our thanks also go to Junior and the entire crew of the Tumbira who helped to make our travels so enjoyable. I have many satisfying memories of seeing amazing world rarities on forest trails and sipping cold caipirinhas from the top deck of the boat as river dolphins slipped past us and nighthawks danced overhead with the stunning backdrop of incredible Amazonian sunsets.

Muito obrigado!

STRAIGHT-BILLED WOODCREEPER (Dendroplex picus)
ZIMMER'S WOODCREEPER (Dendroplex kienerii) – Seeing this riverine woodcreeper so well late in the tour was wonderful, especially as it was foraging on termites in a manner recently documented by Micah during his masters research.
RED-BILLED SCYTHEBILL (Campylorhamphus trochilirostris snethlageae) – We found this and had incredible views in river edge habitat late in the tour. Wow!
CURVE-BILLED SCYTHEBILL (RONDONIA) (Campylorhamphus procurvoides probatus)


The magnificent Tumbira was our home for the majority of the tour: air-conditioned cabins, a beautiful dining room and bar on deck two, and that entire top deck that became a mobile cotinga-/swift-/raptor-/parrot-/antbird-/dolphin-watching platform whenever we needed it. What a wonderful vessel! Photo by guide Tom Johnson.

RONDONIA WOODCREEPER (Lepidocolaptes fuscicapillus) – This is the local version of Lineated Woodcreeper that was recently split and given species-level status.
SLENDER-BILLED XENOPS (Xenops tenuirostris) – Excellent! Though a Paradise Tanager and Slaty-capped Shrike-Vireo came through and tried to distract us, we eventually nailed some good views along the Maués-Açu. Great tour for Xenops, with three in the genus Xenops plus the odd Rufous-tailed [not really a] Xenops.
PLAIN XENOPS (Xenops minutus)
STREAKED XENOPS (Xenops rutilans)
POINT-TAILED PALMCREEPER (Berlepschia rikeri)

BUFF-THROATED FOLIAGE-GLEANER (Automolus ochrolaemus)
PLAIN SOFTTAIL (Thripophaga fusciceps obidensis) – These gregarious ovenbirds came in right overhead and made quite a stir as they perched side-by-side and bobbed around.
RUSTY-BACKED SPINETAIL (Cranioleuca vulpina)
PARKER'S SPINETAIL (Cranioleuca vulpecula) – A stop in river island cane habitat on our final evening yielded some wonderful views of these birds - icing on the cake. Check out Bret's video embedded elsewhere in this triplist to get a sense of our final evening.

YELLOW-MARGINED FLYCATCHER (ZIMMER'S) (Tolmomyias assimilis assimilis)
YELLOW-MARGINED FLYCATCHER (SUCUNDURI) (Tolmomyias assimilis sucunduri) – This rather distinct (perhaps species-level) form of Yellow-margined Flycatcher is recently recognized and we were please to find one in the vicinity of Repartimento that actually came down extremely low for such a canopy-loving species.

THREE-STRIPED FLYCATCHER (Conopias trivirgatus)
STREAKED FLYCATCHER (Myiodynastes maculatus)
ISLAND STREAKED FLYCATCHER (Myiodynastes [maculatus] sp. nov.) – This is the pale, island form of Streaked Flycatcher that could be a species-level taxon. We found a few at the end of the tour, but the most memorable was when we pulled the Tumbira right into shore at a nice spot in the river and had one of these striking flycatchers perched in full sunlight about 5 meters away.
PIRATIC FLYCATCHER (Legatus leucophaius)
VARIEGATED FLYCATCHER (Empidonomus varius)
CROWNED SLATY FLYCATCHER (Empidonomus aurantioatrocristatus) – Part of the group saw one perched high in a roadside tree during a Borba "breakdown".


When Guianan Red-Cotinga is on offer, everyone gathers around Bret! Photo by guide Tom Johnson.

SULPHURY FLYCATCHER (Tyrannopsis sulphurea)
WHITE-THROATED KINGBIRD (Tyrannus albogularis) – These austral migrants winter along the Amazon - on our final days along the Dos Ramos and the Amazona proper, we found lots and got to work on separating them from the rather similar-looking Tropical Kingbird.
TROPICAL KINGBIRD (Tyrannus melancholicus)
FORK-TAILED FLYCATCHER (Tyrannus savana)
Cotingidae (Cotingas)
GUIANAN RED-COTINGA (Phoenicircus carnifex) – On one day when we split up and some went with Micah to retrieve his camera trap, the rest of the group was fortunate to see nicely a dingy male (perhaps an immature?) of this species.
SPANGLED COTINGA (Cotinga cayana)
SCREAMING PIHA (Lipaugus vociferans)
WHITE-TAILED COTINGA (Xipholena lamellipennis) – Excellent! We were fortunate to see a few of these handsome cotingas perched up in treetops on the tour. Though at some distance, we were able to set up scopes from the stable top deck of Tumbira to see one nicely.

We had some lovely experiences with Pavonine Quetzals near Borba. Photo by guide Micah Riegner.

FLAME-CROWNED MANAKIN (Heterocercus linteatus) – Wow! We gathered together in our canoes and watched in excitement as a beautiful male jumped out on a horizontal branch over the water and showed off for half a minute before skedaddling back into a thicket. Fabulous.
CRIMSON-HOODED MANAKIN (Pipra aureola) – A striking male posed overhead for us during one of our canoe outings away from the Tumbira.

RUFOUS-BROWED PEPPERSHRIKE (Cyclarhis gujanensis) [*]
GRAY-CHESTED GREENLET (Hylophilus semicinereus)

This was the view from the top deck of Tumbira as we cruised along. "May he rest in peace"?? We must have been talking about a blank spot in our checklist that had been recently filled in. Video by guide Bret Whitney.

Done birding for the day? No problem - sip a cold drink and listen to Bret present about Amazonia biogeography using the high-definition screen in the restaurant! We had an in-depth discussion of the forces that have driven Amazonia to generate its spectacular biodiversity, and why the Madeira-Tapajos Interfluvium is so particularly interesting. It is kind of unbelievable to be able to do this while cruising down a river in the middle of Brazil. Video by guide Tom Johnson.
