Bolivia: The Andes and Chaco Lowlands trip report

October 2014By Eduardo Ormaeche

This was our second Bolivia birding tour, and it was a great success for everybody. Only infrequently visited by birders, Bolivia hosts 1432 species, with 20 endemics (including two magnificent macaws) and 48 threatened species. It is without doubt the richest landlocked country in the world in terms of species diversity.

Our birding tour to Bolivia allowed us to explore different habitats and ecosystems within this remote country, including tropical savannas, wetlands, the Llanos de Moxos around Trinidad – a tropical savanna ecoregion of northern Bolivia and home of the endangered Blue-throated Macaw, and the Chiquitania woodlands – a transitional ecotone type of xerofitic vegetation and Acacia-like trees, which is located between the Amazon rainforest, the Cerrado, and the Gran Chaco. In the Gran Chaco, an impenetrable dry woodland habitat, we spent some time in search of a handful of specialists and the most-wanted Black-legged Seriema.

We crossed through lush cloudforest and upper tropical forest and also birded the dry valleys between Comarapa and Santa Cruz de la Sierra, the high Andes in the Altiplano (the “High Plateau”), and Lake Titicaca, the highest navigable lake of the world and home to the flightless Titicaca Grebe.

We spent 17 days exploring and enjoying this unique country during a special tailor-made tour, and we had a great time from the moment we descended from the plane. We were looking at every single bird that crossed our path, but also with a special focus on numerous targets – birding without pressure of any kind. And we enjoyed the wildlife and the magnificent scenery as well. We managed to record 408 species during the trip, including birds of 62 different families, and 24 parrots (including seven macaws).

This will remain a highly memorable tour for the leader, because, among many special moments and birds and good black beers, I had the good fortune to spend my birthday in the great company of Paul, Sue, and Herman while watching the endemic and endangered Red-fronted Macaw in the Saipina canyon.

TINAMIFORMESTinamidaeGrey Tinamou (H) Tinamus tao This large tinamou was heard a couple of times at Refugio Los Volcanes. Listed as Vulnerable.Undulated Tinamou Crypturellus undulatus The classic bird call of the Amazon rainforest. One bird was seen briefly by Sue and the leader at the gallery forest of Beni. We were almost ready to see it again, when I realized we were standing below a Tangarana tree full of fire ants with several climbing on our trousers. Brown Tinamou (H) Crypturellus obsoletus Heard at Refugio Los Volcanes. The tinamous belonging to the genus Crypturellus are usually notoriously difficult to see.Tataupa Tinamou (H) Crypturellus tataupa Heard in the lowlands of Santa Cruz de la SierraSmall-billed Tinamou (H) Crypturellus parvirostris Distantly heard in the Botanical Gardens of Santa Cruz de la SierraRed-winged Tinamou Rhynchotus rufescens Two birds were seen during our search at the grasslands of the Viru Viru International Airport in Santa Cruz de la Sierra.

We heard some individuals on the first afternoon, but without success, and spent the whole next morning on the search. At the eleventh hour, and after we had lost all hope and decided to drive back to town, the deity of ornithology heard our prayers and rewarded us with the sight of an immaculate individual standing next to the road, waiting for us, and allowing us good views.

Listed as VulnerableBlue-and-yellow Macaw Ara ararauna Several birds seen in the Llanos de Moxos in BeniBlue-throated Macaw (E) Ara glaucogularis The bird of the trip, and the main reason why we went to Trinidad. This is an endemic and endangered species. Until 1992 their habitat and location was completely unknown, until an expedition led by the ornithologist Charles Munn discovered the site. The species is listed as Critically endangered, with a world population of less than 130 mature individuals. We had excellent views of two pairs in Beni.Red-and-green Macaw Ara chloropterus Seen in BeniGolden-collared Macaw Primolius auricollis Great views of few pairs in Beni and on our way to the Chaco

Chestnut-fronted Macaw Ara severus Excellent views in Beni. We got several individuals, even roosting in trees and the church tower of Trinidad.Red-fronted Macaw (E) Ara rubrogenys Another spectacular bird endemic to Bolivia. We had great scope views of a few pairs roosting in the Saipina cliff. Listed as Endangered; the world population is estimated at 130 pairs.Blue-crowned Parakeet Thectocercus acuticaudatus Seen in the lowlandsMitred Parakeet Psittacara mitratus Seen in the dry valleysWhite-eyed Parakeet Psittacara leucophthalmus Seen near Santa Cruz de la SierraDusky-headed Parakeet Aratinga weddellii Seen in BeniPeach-fronted Parakeet Eupsittula aurea One bird seen well in BeniGreen-cheeked Parakeet Pyrrhura molinae Nice views of this handsome parakeet around Santa Cruz de la Sierra, the Bermejo road, and Refugio Los VolcanesMonk Parakeet Myiopsitta monachus luchsi Excellent views at the Saipina cliff, where the Red-fronted Macaw roosts. Collar (1997) treated Andean luchsi as a separate species from Myiopsitta monachus, based on differences in plumage and nest site; this taxon was formerly (e.g., Cory 1918) treated as a separate species, but Peters (1937) considered them conspecific. Russello et al. (2008) found that luchsi was genetically isolated from the lowland populations. At present, IOC treats it as a “proposed and probably good split”. Andean Parakeet Bolborhynchus orbygnesius Excellent views of a tiny flock at Cerro Tunari. A most-wanted species!

Recent genetic evidence supports observed vocal and plumage differences in this species complex. The SACC has recently elevated the northern, central, and southern populations of Cinclodes fuscus to species level (named as Chestnut-winged Cinclodes C. albidiventris, Cream-winged Cinclodes C. albiventris, and Buff-winged Cinclodes C. fuscus, respectively).

We saw the samaipatae subspecies around Torrecillas. The SACC says “The superciliosa subspecies group (including samaipatae), was formerly (e.g., Cory & Hellmayr 1925, Peters 1951, Meyer de Schauensee 1970) considered a separate species ("Buff-browed Spinetail") from S. azarae, but see Remsen et al. (1988).”Cinereous-breasted Spinetail Synallaxis hypospodia One seen well in BeniPlain-crowned (“White-lored”) Spinetail (H) Synallaxis gujanensis inornata This taxon was heard only in Beni.
