Amazonian Motmot Momotus momota One bird was seen well in the Botanical Gardens of Santa Cruz de la Sierra. The “Amazonian Motmot” complex has recently been split into five species, based on plumage patterns, biometrics, and vocalizations, supplemented by information on geographic distributions and ecology. The split is as follows:
PICIFORMES Galbulidae Rufous-tailed Jacamar Galbula ruficauda Seen in Beni and at Valle Sanchez Bucconidae Chaco Puffbird Nystalus striatipectus Seen at several locations. This taxon was split from Spot-backed Puffbird. Black-fronted Nunbird Monasa nigrifrons Seen in Beni and the Botanical Gardens of Santa Cruz de la Sierra Ramphastidae Blue-banded Toucanet Aulacorhynchus coeruleicinctis A brief view of one individual flying off from the nest at Refugio Los Volcanes Chestnut-eared Aracari Pteroglossus castanotis Seen in the lowlands Toco Toucan Ramphastos toco Great views of a few birds in the Chaco and at Refugio Los Volcanes Picidae White-wedged Piculet Picumnus albosquamatus One seen well at Valle Sanchez White Woodpecker Melanerpes candidus Two birds flying by in the Chaco during the Seriema search Yellow-tufted Woodpecker Melanerpes cruentatus A few noted in Santa Cruz de la Sierra Bar-bellied Woodpecker Veniliornis nigriceps One bird was seen in a mixed flock on the upper Coroico road, White-fronted Woodpecker Melanerpes cactorum Great views of several birds in the Chaco and in the arid valleys near Comarapa Andean Flicker Colaptes rupicola Seen in the Altiplano Campo Flicker Colaptes campestris Two birds spotted on a termite mound in Santa Cruz de la Sierra Lineated Woodpecker Dryocopus lineatus Seen well in the gallery forest of Beni FALCONIFORMES Falconidae Mountain Caracara Phalcoboenus megalopterus Common in the Altiplano Yellow-headed Caracara Milvago chimachima One seen on the Beni marshes Southern Crested Caracara Caracara plancus Common in the lowlands Laughing Falcon Herpetotheres cachinnans One bird was seen in the Chaco Aplomado Falcon Falco femoralis Great views in the Chaco and at Lake Titicaca American Kestrel Falco sparverius Common PSITTACIFORMES Psittacidae Military Macaw Ara militaris Great views of two birds flying low during our way to the Chaco. Listed as Vulnerable Blue-and-yellow Macaw Ara ararauna Several birds seen in the Llanos de Moxos in Beni Blue-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 Beni Golden-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 lowlands Mitred Parakeet Psittacara mitratus Seen in the dry valleys White-eyed Parakeet Psittacara leucophthalmus Seen near Santa Cruz de la Sierra Dusky-headed Parakeet Aratinga weddellii Seen in Beni Peach-fronted Parakeet Eupsittula aurea One bird seen well in Beni Green-cheeked Parakeet Pyrrhura molinae Nice views of this handsome parakeet around Santa Cruz de la Sierra, the Bermejo road, and Refugio Los Volcanes Monk 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! Cobalt-winged Parakeet Brotogeris cyanoptera A flock was noticed in Beni. Yellow-chevroned Parakeet Brotogeris chiriri Common around the Santa Cruz de la Sierra lowlands Grey-hooded Parakeet Psilopsiagon aymara Great views of two birds on a windy afternoon at La Siberia cloudforest Blue-winged Parrotlet Forpus xanthopterygius Seen well in the lowlands Blue-headed Parrot Pionus menstruus Seen by Paul and the leader in the lowlands Scaly-headed Parrot Pionus maximiliani Seen well in the Chaco Turquoise-fronted Amazon Amazona aestiva Seen in the Chaco and around Saipina Yellow-crowned Amazon Amazona ochrocephala Two birds were seen well in the lowlands. Scaly-naped Amazon Amazona mercenarius Fly-by of a few birds at the upper parts of the Coroico road PASSERIFORMES Furnariidae Rock Earthcreeper Ochetorhynchus andaecola Seen well at Cerro Tunari Chaco Earthcreeper (H) Tarphonomus certhioides One bird was heard in the Chaco but we didn’t try, because it wasn’t a lifer for the folks and we were trying desperately for the Black-legged Seriema. Bolivian Earthcreeper (E) Tarphonomus harterti It took a while, but fortunately we had great views of this country endemic in the dry gullies of Saipina. Cream-winged Cinclodes Cinclodes albiventris Seen at Cerro Tunari and in the Altiplano. 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). White-winged Cinclodes Cinclodes atacamensis Seen at Cerro Tunari Rufous Hornero Furnarius rufus Common in the lowlands. The national bird of Argentina Crested Hornero Furnarius cristatus One seen very well Brown-capped Tit-Spinetail Leptasthenura fuliginiceps One bird was seen in the Polylepis forest of Cerro Tunari. Tawny Tit-Spinetail Leptasthenura yanacensis Great views of one bird at Cerro Tunari. Listed as Near-threatened Black-throated Thistletail (E) Asthenes harterti Great views of one bird in Chapare Short-billed Canastero (H) Asthenes baeri Heard in the Chaco Puna Canastero Asthenes sclateri Seen well on the way to La Cumbre Scribble-tailed Canastero Asthenes maculicauda Only one bird seen below La Cumbre on the way to the Coroico road Maquis Canastero Asthenes heterura Great views at Cerro Tunari. Listed as Near-threatened Rusty-vented Canastero Asthenes dorbignyi Seen well at Cerro Tunari Cordilleran Canastero Asthenes modesta Seen in the upper parts of Cerro Tunari Plain Softtail Thripophaga fusciceps This is the nominate subspecies, which is larger than the other two and has a different nest structure and a unique voice. Great views in Beni Ochre-cheeked Spinetail Synallaxis scutata Two birds were see nicely along the Monteagudo road on the way to the Chaco. Sooty-fronted Spinetail Synallaxis frontalis One seen well in the lowlands Azara’s Spinetail Synallaxis azarae samaipatae Seen at La Siberia cloudforest. 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 Beni Plain-crowned (“White-lored”) Spinetail (H) Synallaxis gujanensis inornata This taxon was heard only in Beni. Light-crowned Spinetail Cranioleuca albiceps Crippling views of a pair in La Siberia cloudforest and a few others in the Chapare Stripe-crowned Spinetail Cranioleuca pyrrhophia Seen well in the Chaco and the arid valleys Rufous-fronted Thornbird Phacellodomus rufifrons Relatively common in the Santa Cruz de la Sierra lowlands Little Thornbird Phacellodomus sibilatrix This Chaco specialist was seen well along the track to the Paraguayan border.

The population in Beni lacks the gray crest. Grey-throated Leaftosser Sclerurus albigularis Very elusive this year; we managed to see only a non-cooperative individual at Refugio Los Volcanes. Listed as Near-threatened Olivaceous Woodcreeper Sittasomus griseicapillus Seen at Beni and Refugio Los Volcanes. Possibly as many as five species-level taxa are involved in this complex. Black-banded Woodcreeper Dendrocolaptes picumnus Seen at Refugio Los Volcanes Straight-billed Woodcreeper Dendroplex picus Seen well in Beni Buff-throated Woodcreeper (H) Xiphorhynchus guttatus Heard in Beni Narrow-billed Woodcreeper Lepidocolaptes angustirostris Several birds seen on the trip, especially in the Chaco Montane Woodcreeper Lepidocolaptes lacrymiger Seen in the cloudforest of Tablas Monte Thamnophilidae Giant Antshrike Batara cinerea One of the greatest birds of the trip.

A highlight of the tour Barred Antthrush (H) Chamaeza mollissima Heard only in the cloudforest at Tablas Monte Grallariidae Rusty-faced Antpitta (E, H) Grallaria erythrotis Despite our efforts we could not get this endemic this time. It was very close, though, at Tablas Monte. Conopophagidae Slaty Gnateater (H) Conopophaga ardesiaca What frustration! This species was very quiet this year, with only one bird responding once, but not enough to come to show. This is the first time I failed to show this species. Rhinocryptidae Bolivian White-crowned Tapaculo Scytalopus bolivianus Crippling views of this always shy tapaculo at Refugio Los Volcanes. We saw all tapaculos available on this tour. Trilling Tapaculo Scytalopus parvirostris Seen well at La Siberia cloudforest Diademed Tapaculo Scytalopus schulenbergi First Paul and I had a good view of one bird responding to the tape, but unfortunately it was missed by Sue. Only at the end of the day we managed to get another for Sue at the upper parts of the Coroico road. This species was described only in 1992. My reputation was at stake, fortunately we got one! Puna Tapaculo Scytalopus symonsi Seen hopping on a rock in the middle of the stream at Cerro Tunari Melanopareiidae Olive-crowned Crescentchest Melanopareia maximiliani Oh yes!! Incredible views of two birds not far from the road. This is the third species of crescentchest I have seen with Paul and Sue.
