Bolivia is one of those well-kept secrets; in the birding world it tends to be eclipsed by Ecuador, Peru and Brazil, whose feeder-adorned lodges attract birders worldwide. That said, for those who are up for some adventure, Bolivia is a fabulous, fabulous place to bird. The range of habitats crammed within its borders is truly astounding. From moss-laden Yungas ridgetops dripping with ferns and orchids on the eastern flank of the Andes to steep cactus gorges in their rain shadow—and from hot Chiquitania lowlands around Santa Cruz, to the frigid Puna at 4700 m where ground-tyrants and diuca-finches frolic through Ichu bunch grass, to the colossal sandstone massifs of Refugio Los Volcanes towering over the southernmost fingers of Amazonia, Bolivia is truly a birder’s paradise. In our 2-week pursuit of antpittas, canasteros, sunbeams and salteñas, we traversed these awesome landscapes and encountered some of the country's most sought-after avifauna. We were bedazzled by the turquoise rump of the endemic Black-hooded Sunbeam, baffled by a Giant Antshrike (a thamnophilid, the size of a Sharp-shinned Hawk!), and bewildered by Rufous-bellied Seedsnipe, who eke out existence in the barren, wind-swept Puna.

Our adventure began right outside the Viru Viru airport in Santa Cruz where we scoped Red-winged Tinamous and Greater Rheas in the open countryside. We then birded the Chiquitania woodland along the Rio Pirai, where we had our first encounters with Rufous-fronted Thornbirds, Bolivian Slaty-Antshrikes and a noisy group of White-eared Titis, not to mention a Red-legged Seriema perusing the edge of the road! From Santa Cruz, we zigzagged up the Andean foothills to Refugio los Volcanes (not actually volcanoes) where we spent the next few days admiring Military Macaws against the sandstone walls. We saw other birds there too of course, like the elusive Short-tailed Antthrush, Black-goggled Tanager, and Slaty Gnateater.

We then drove to Comarapa, a town surrounded by dust, cacti and a bunch of Bolivian endemics. Here, we had phenomenal looks at a pair of Cream-backed Woodpeckers, probably the closest thing there is to an Ivorybill, the endemic Red-fronted Macaw, and the Bolivian Earthcreeper, an ovenbird about the size and shape of a Canyon Wren. For many of us, the highlight of the tour was the Giant Antshrike. We heard one calling from way up a gully, so we played some tape and waited. Almost 10 minutes later, the bird appeared right in front of us-- it was shockingly huge, with a ferocious hooked bill and jay-like crest. We watched it call out in the open, grab a tarantula from the ground and then disappear into the dense lichen-covered undergrowth.

The humid slopes of Cochabamba are some of the birdiest in Bolivia. We spent 3 days working different elevations from bromeliad-covered foothill forest at 1700 m all the way to treeline at 3000 meters where we saw Rufous Antpittas, Diademed Tapaculos and even a Barred Antthrush skulking through the mossy understory. We also explored the slopes of Cerro Tunari, one of the highest peaks on the Cochabamba horizon, where we saw the aptly-named Cochabamba Mountain-finch, White-winged Cinclodes and Wedge-tailed Hillstar in the dry Andean scrub. In a patch of Polylepis (a high elevation tree with red flaky bark) we saw Giant Conebill and Tawny Tit-Spinetail, two birds I had been hoping to see. The Black-hooded Sunbeam is one of the most sought-after Bolivian endemics—and for good reason. Its velvet black plumage set against an iridescent turquoise rump, orange tail feathers and gleaming white upside-down “V” on the chest make it a sight to behold. We saw several of these impressive hummers pollinating Mutisia flowers at tree line.

For the last leg of the tour we flew to La Paz and drove the old Coroico Road, a narrow dirt track with a seemingly endless drop-off that twists and turns through cloud forest as far as the eye can see. Turns out it’s one of the best birding roads in all of South America! Dawn found us at La Cumbre, the highest point of the tour at 4770 m where we watched a pair of Rufous-bellied Seedsnipe pecking through a bleak gravel slope. By lunchtime we were in the cloud forest watching Hooded Mountain Toucans, spunky White-collared Jays and a pair of Black-and-chestnut Eagles weaving in and out of the clouds. Dan showed us to a spot where we saw a Scimitar-winged Piha, a poorly-known specialty of humid montane forest. When we returned to La Paz, we day-tripped to Lake Titicaca at the Peruvian border. According to Carlos, our driver, the Bolivians have the “Titi” side and the Peruvians have the “caca” side. From shore we were able to scope Titicaca Grebes among rafts of Slate-colored Coots and other Andean waterbirds. Both Short-billed and Correndera Pipits were vocalizing in the grasslands: the Short-billed in the dry grass and the Correndera in the wet. We had our final pizza lunch on the road to Sorata and saw Berlepsch’s Canastero, a bird restricted to the valley surrounding the town.

Overall, the tour ran smoothly with few logistical complications. Special thanks to Carlos for his terrific driving (especially for keeping us alive on the Coroico Road!), Benita for her continual supply of “aguita, Coca Cola, Coca Zero,” Herman for that wonderful French toast we had in the Yungas, and Edwin and Zacaria for their assistance throughout the tour. Dan and I would like to thank all of you for joining us on this aventura; we had a great time and look forward to birding with you again.
