ITINERARY

November 11th:
We all arrived from Riberalta to Trinidad by flight, later than scheduled, birded the Loma Suarez Road in Trinidad on the way to the hotel.

November 12th: Early morning start to Loreto and then Laredo (The Beni Pantanal and cattle ranches) in Trinidad. It had rained heavily two days before and we were lucky to make it along Esperancita ranch track to the macaw area. We were delighted to see almost immediately a pair of Blue-throated Macaws at a nest-box. We enjoyed more and also their larger cousins the Blue and Yellow Macaws. Very wet trails indeed and the vehicles struggled to get out onto the main road where we did some nearby birding with great success before a really typical cowboy lunch at a restaurant in Loreto – pork and locally made hot sauce- yum! Afternoon birding along a track through gallery forest near the Ibare port of Ballvariana and back to our hotel via a re-fuelling stop at the local shops.

November 13th: We returned to the same trail at Ballerviana port for Unicolored Thrush and then lunched at Loma Suarez in the baking heat. Trail to Colorado Lake Trail, Rio Ibare, Loma Suarez and Laguna Suarez wetlands in Trinidad.

November 14th: Really early start and then the long journey from Trinidad to Santa Cruz de la Sierra by bus (dumping Barry along the way) and into Refugio Los V olcanes.

November 15th and 16th: Trails (Loro, Cafetal, Orquideas, Sirari, Condor and main road) in Refugio Los Volcanes.

November 17th: Refugio Los Volcanes to Valle Grande by bus, (Samaipata, Mairana, Quirusilla village and Laguna Esperanza).

November 18th: Lomas Larga and Campo Casa roads and surroundings in Valle Grande.

November 19th: Valle Grande to Comarapa by bus, (Saipina and Muyurina community trail).

November 20th: Saipina, Rio Misque and Anamal community trail near Comarapa.

November 21st: Comarapa to Cochabamba by bus, (La Siberia and Mojos village).

November 22nd: Tablas Montes and San Miguelito “Chapare” in Cochabamba.

November 23rd: Quillacollo, Cerro Tunari Road and San Miguel Village in Cochabamba.

November 24th: Cochabamba to Oruro by bus, (Quicacollo, Bombeo village and Uru-uru lake).

November 25th: Oruro to Chullumani by bus, (Pongo village, Quime and Inquisive).

November 26th: Chulumani to Coroico by bus, (Huacane, Apa-Apa private reserve and Coripata).

November 27th: El Chairo and the Cotapata National Park in Coroico.

November 28th: Coroico to La Paz by bus, (Death road, Chusquipata, la Cumbre and the Titicaca lake). Arrival at our lakeside hotel with Flightless Grebes available form the dining room. Meet up with Barry.

November 29th: La Paz to Apolo by jeeps, (Charazani). Early start into the unknown-none of us had done this before and we set off over the highlands stopping at a lovely village for trout and soup – what was in it I do not know! Onwards – it was really hot when we passed some nice looking yungas forest so we did not stop except for a Fasciated Tiger Heron and some pics of an amazing waterfall. We rolled into Apolo earlier than expected, some had lunch and we birded the upper part of the forest dropping down towards the Machariapo Valley. Arriving at the convent which would be our home for 3 nights we were warmly greeted by Sister Lutgarda and installed in our small but adequate rooms. Dinner was very good as it was each night.

November 30th: Muiri Community and the upper Machariapo Valley in Apolo. Cotinga Day! We left early for the road to Atuen with William Feruffino who has worked on conservation of the Palkachupa Cotinga with the Armonia NGO. He took us to a friend’s farm and we wandered down a track seeing many Cotingas. We birded our way back to Apolo – glad to see Dark-throated Seedeater. Had a great lunch at a local restaurant and then into the Machariapo drainage once more for the afternoon.

December 1st: Upper Machariapo Valley (the Madidi National Park) in Apolo. Today was our day to bird the lower part of the valley and we got to the Machariapo River crossing to find it easy to negotiate, we then got about 20 minutes birding at the key site until the heavens opened and it rained cats and dogs! We waited but William after a few hours of rain suggested we cross back over the river in case of river rise which we did and birded the rest of the day the Apolo side of the river.

December 2nd: Apolo to La Paz by jeeps, (Correo and Charazani). We stopped in some yungas forest early, had lunch at a truck stop, birded the higher regions in the heat of the day and returned to our hotel on the shores of Lake Titicaca.

December 3rd: Some of us left for International Departures, some did a trip for the endemic Berlepshe’s Canastero above Sorata.

SPECIES LIST

Brazilian Teal - Amazonetta brasiliensis. Around ten along road from Trinidad to Santa Cruz.

Torrent Duck - Merganetta armata. About twelve seen along the road from Charazani to Apolo.

Crested Duck - Lophonetta specularioides. Several seen along road from Cochabamba to Oruro and a few more from La Paz to Charazani. The SACC says “Lophonetta specularioides is often (e.g., Hellmayr & Conover 1948a, Johnsgard 1979) placed in Anas, but see Johnson & Sorenson (1999) for return to monotypic Lophonetta, as in Meyer de Schauensee (1970) and Blake (1977).

Yellow-billed Teal - Anas flavirostris. Common along road from Cochabamba to Oruro. The SACC says “Hellmayr & Conover (1948a) and many earlier classifications treated andium (Andean Teal) as a separate species from A. flavirostris. Many authors, from Meyer de Schauensee (1970) to Dickinson (2003), have treated andium as a subspecies of A. flavirostris. Anas andium was considered a separate species from Anas flavirostris by Ridgely et al. (2001), and this was followed by Hilty (2003). SACC proposal passed to recognize andium as separate species. 7 Jaramillo (2003) further suggested that the subspecies oxyptera may also deserve recognition as a separate species from A. flavirostris.

Yellow-billed Pintail - Anas georgica. Six seen along road from Cochabamba to Oruro.

Puna Teal - Anas puna. Common in the Lake Uru-Uru.

Cinnamon Teal - Anas cyanoptera. Common in the Lake Uru-Uru.

Andean (Ruddy) Duck - Oxyura (jamaicensis) ferruginea. Two seen on the high lake along road from Charazani to La Paz. Andean populations have often (e.g., Hellmayr & Conover 1948a, Siegfried 1976, Sibley & Ahlquist 1990, AOU 1998, Ridgely & Greenfield 2001, Jaramillo 2003, del Hoyo & Collar 2014) been treated as a separate species, O. ferruginea ("Andean Duck" or "Andean Ruddy-Duck"). However, see Adams and Slavid (1984), Fjeldså (1986), McCracken & Sorenson (2005), and Donegan et al. (2015) for rationale for treating them as conspecific, as done previously (e.g., Blake 1977, Johnsgard 1979), and then followed by Fjeldså & Krabbe (1990), Carboneras (1992f), and Dickinson & Remsen (2013). Siegfried (1976) and Livezey (1995) considered ferruginea to be more closely related to O. vittata than to O. jamaicensis, but McCracken & Sorenson (2005) showed that this is incorrect.

CHACHALACAS, GUANS & CURASSOWS (Cracidae)

Andean Guan - Penelope montagnii. Four seen at the APA-APA Reserve in Chullumani.

Red-faced Guan - Penelope dabbenei. About eight seen along road to Lomas Larga in Valle Grande. Range Restricted.

GREBES (Podicipedidae)

White-tufted Grebe - Rollandia Rolland. About eight seen at Uru-Uru lake in Oruro. Specific name Podiceps rolland. rolland= In honor of Thomas Pierre Rolland, Master Gunner (1776-1847) French Navy, of the corvette L’Uranie which circled the globe 1817-1848.

Titicaca Grebe - Rollandia microptera. About five seen a Lake Titicaca, near the hotel. Sometimes this grebe is known as the Short-winged Grebe, but Titicaca Grebe is a much more appropriate name as that lake forms the main part of its distribution. It is also found farther south in lakes Popoo and Uru-uru. Therefore, it is restricted to the Altiplano of Bolivia and Peru. The most curious aspect of this grebe is that it is flightless, a trait it shares with the Peruvian Junín Grebe (Podiceps taczanowskii) and interestingly that grebe is in a different genus so the loss of flight occurred independently twice in South American grebes. The Titicaca Grebe was at one time quite common and estimates ranged as high as 10,000 individuals, but this grebe has been on a decline for at least the last two decades and this is partially blamed on the use of fishing nets which are catching the grebes and drowning them, current estimates are that 2000 remain. ENDANGERED.

Least Grebe - Tachybaptus dominicus. One seen on the pond in la Siveria, road from Comarapa to Cochabamba.

FLAMINGOS (Phoenicopteridae)

Chilean Flamingo - Phoenicopterus chilensis. About over a thousand seen at Uru-Uru lake in Oruro.

Rufous Nightjar - Antrostomus rufus. One seen at the Machariapo Valley.

SWIFTS (Apodidae)

White-chested Swift - Cypseloides lemosi. Saw a few near Saipina – this is a very localized overlooked swift and on what with the advances of digital photography is being recorded more and more.

Rothschild’s Swift – Cypseloides rothschildi. About ten seen near Saipina. The Rothschild’s Swift was long considered to be conspecific with the Sooty Swift (Cypseloides fumigatus), which species is largely confined to south-eastern South America. Like other Cypseloides species, Rothschild’s Swift is a medium-sized swift with long, broad wings, and a short square-ended tail. Its plumage is entirely mid brown; in the field separation from Sooty Swift is probably impossible, except on distribution. The present species is more or less confined to northwest Argentina into Bolivia. Very poorly known indeed, virtually nothing has been published concerning the Rothschild’s Swift’s ecology and behaviour.

Amethyst-throated Sunangel - Heliangelus amethysticollis. Couple seen at Tablas Montes and another seen along death road to Chuzquipata. From the Greek Helios =sun, Angelos = angel. From the habit of this genus of lifting their wings monetarily as in stylized angel paintings, on alighting on a twig.

Rufous-crested Coquette - Lophornis delattrei. One female seen in El Chairo near the Cotapata National Park. Named for Adolphe de Lattre, French collector in Mexico and Colombia.

Speckled Hummingbird - Adelomyia melanogenys. One seen along the way from Chullumani to Coroico.

Rufous-booted Racket-tail - Ocreatus addae. One feeding on flowers in el Chairo along trail to Cotapata National Park. The Racket tailed Puffleg was unknown in life but specimens existed in various London cabinets, whence a drawing was sent in 1832 by Mr. Underwood on behalf of Charles Stokes, a London stockbroker and collector. An article in Zootaxa 4200 (1): 083–108 2016 Biogeography and taxonomy of racket-tail hummingbirds (Aves: Trochilidae: Ocreatus): evidence for species delimitation from morphology
and display behavior by KARL-L. SCHUCHMANN, ANDRÉ-A. WELLER & DIETMAR JÜRGENS provided evidence from plumage and behavior that Ocreatus underwoodii should be treated as four species, with the subspecies addae, annae, and peruana elevated to species rank. If this is so the species would be thus:
White-booted Racket-tail O. underwoodii Venezuela to W Ecuador;
Peruvian Racket-tail O. peruvianus E Ecuador to NE Peru;
Anna’s Racket-tail O. annae Pasco to Cuzco (endemic);
Rufous-booted Racket-tail O. addae Bolivia (endemic).

Violet-fronted Brilliant - Heliodoxa leadbeateri. Several seen feedings on flowers in el Chairo along trail to Cotapata National Park.

Golden-tailed Sapphire - Chrysuronia oenone. One seen along the road from Apolo to Charazani.

Rufous-throated Sapphire - Hylocharis sapphirina. One seen very well at Loreto in Trinidad.

White-chinned Sapphire - Hylocharis cyanus. One male seen at Colorado lake trail, near Loma Suarez in Trinidad.

ANHINGA (Anhingidae)

Anhinga - Anhinga anhinga. Common in Trinidad.

RAILS (Rallidae)

Gray-cowled Wood-Rail - Aramides cajaneus. Seems common in Loreto area.

Chestnut-headed Crake - Anurolimnas castaneiceps. One seen along road in the Machariapo Valley.

Plumbeous Rail - Pardirallus sanguinolentus. Heard only.

Common Gallinule - Gallinula galeata. Common at Uru-Uru lake in Oruro. Note that this species is a recent split from Common Moorhen of the old world (Gallinula chlorops) on the basis of morphological, genetic, and vocal differences (Groenenberg et al 2008).

Giant Coot - Fulica gigantea. About twenty in the high Andean ponds, on the way from Charazani to La Paz.

Puna Plover - Charadrius alticola. Three seen at Uru-Uro lake in Oruro.

STILTS AND AVOCETS (Recurvirostridae)

Black-necked (White-necked) Stilt - Himantopus mexicanus. About fifty seen at Uru-Uro lake in Oruro. Taxonomy is a bit confusing. The SACC says “Himantopus mexicanus was formerly considered a subspecies of Old World H. himantopus (“Common Stilt”). Some authors have treated southern South American melanurus (White-backed Stilt) as a separate species. The six taxa in the genus Himantopus form a near-globally distributed super species and between one to six species-level taxa recognized by various authors. Virtually no data are available relevant to taxon-ranking of allopatric populations. The contact between mexicanus and melanurus in South America, where at least some hybridization occurs, affords one of the best opportunities for such study.

Andean Avocet - Recurvirostra andina. About twenty seen at Uru-Uro lake in Oruro.

Largely a terrestrial feeder, reports of stomach contents have shown that grasshoppers are their main prey item.

Cocoi Heron - Ardea cocoi. Five seen on our way to Loreto.

Great Egret - Ardea alba. Common. Formerly placed in either Egretta or the monotypic genus Casmerodius. Called Western Great Egret after the split of Ardea modesta (Eastern Great Egret) from A. alba (Sheldon 1987, Collar 2007, Christidis & Boles 2008).

Whistling Heron - Syrigma sibilatrix. One seen on our way to Loreto.

Capped Heron - Pilherodius pileatus. One seen on our way from Trinidad to Santa Cruz.

Snowy Egret - Egretta thula. Common. Thula’ is an Araucano (Chilean) Indian name for the Black-necked Swan, erroneously given to the Snowy Egret!

Roseate Spoonbill - Platalea ajaja. Five along road from Trinidad to Santa Cruz.

AMERICAN VULTURES (Cathartidae)

Turkey Vulture - Cathartes aura. Common. Jaramillo (2003) suggested that the resident tropical subspecies ruficollis and the southern subspecies group (jota and "falklandica") might merit recognition as separate species from the northern Cathartes aura group.

Greater Yellow-headed Vulture - Cathartes melambrotos. Seen one at El Chairo in Coroico.

Black Vulture - Coragyps atratus. Common. After the opinions of a few 19th century taxonomists were long ignored, recent genetic studies have indicated that New World vultures are modified storks and don’t belong with the raptors; an excellent example of convergent evolution.

King Vulture - Sarcoramphus papa. Seen one after leaving los Volcanes, on our way to Mairana.

Andean Condor - Vultur gryphus. Several seen in la Siberia, from Comarapa to Cochabamba.

OSPREY (Pandionidae)

White-tailed Hawk - Geranoaetus albicaudatus. One seen flying over at Laguna Esperanza in Quirusilla.

Variable Hawk - Geranoaetus polyosoma. Common. Farquhar (1988) concluded that Buteo poecilochrous and B. polyosoma are conspecific, as they were formerly treated (REF); he was unable to find any way to reliably diagnose the two forms using plumage characters or measurements. Ridgely & Greenfield (2001), Jaramillo (2003), and Schulenberg et al. (2007) followed this treatment and suggested "Variable Hawk" be retained for the composite species. Genetic data (Riesing et al. 2003) are consistent with hypothesis that B. polyosoma and B. poecilochrous are conspecific. [incorp. Cabot & De Vries 2003, Vaurie 1962]. SACC proposal passed to treat as conspecific. Cabot & de Vries (2003, 2004, 2010) presented additional data that support their recognition as separate species. SACC proposal to re-elevate poecilochrous to species rank did not pass.
